- Of course they always say they never leave the door open, during this visit the manager said it multiple times but I just grabbed him by the hand and showed him all the times it was left open while I was there.

We don't leave the door open except for all the times we leave the door open.
That's right
We don't leave it open, we set it open.
@@ingiford175 on God 🤣🙏🏼😂
The kids are lucky to have your videos. I wish I had them 30 years ago
You are so right. I am ret. Chemist (hate politics in such) so I watched several hundred videos, especially HVACRs and walked right into the trade. I must confess I was already completely versed from DC through 7200 VAC so just watching furnaces fixed, refrigeration cycle and metering devices, I actually helped seasoned guys when inverter and pulse-width circuit boards were issues diagnose. I scored 98% on Universal 608 and got hired.
Addendum: I worked for an established Family HVAC LLC for a year and asked to be a helper for however long I needed. They put me in a van after three months solo and never looked back. COVID was a huge pain but never missed a day.
Yep something didn’t go through the apprenticeship in my state. I had the license hours & basic HVACR schooling I taught myself & old timer refrigeration mechanic help me get my trade license.
the same people bellyaching that "you're showing the IP address ( a non public IP, but still.. )" are the same people that cover the license plate with their thumb when they take a picture of a car
Whenever I encounter this kind of repeated evaporator frosting issues, I install vinyl clear curtain to stop warm air entering these walk in coolers/freezers....it's an effective way to combat employees leaving cooler doors opend for long.
Come check out my livestream this evening 11/21/22 @ 5:PM (pacific) and I will discuss your question czcams.com/video/ez9USkoW54o/video.html
Employees will end up tearing them down, especially when they get caught in the carts that they shouldn't be shoving into the coolers in the first place.
@@sparklesparklesparkle6318 Understandable. Two weeks worth of cocaine is probably twice the cost of that curtain.
Haha, we used shrink wrap to pull those to the side. They were a PITA and hurt when they smack you in the face from pushing pallets and racks in and out. Some people would actually cut them after being smacked
After being an appliance technician for 42 years and running our family business for 31 of those years, I would often find myself, while melting the ice build up in many domestic refrigerator/freezers, considering the fact that 80 years before I started working in this business removing ice-people would have been PAYING someone to deliver the ice to them! How times have changed.
You demonstrated what I always taught techs- 1: Use your mark 1 eyeballs first and OBSERVE everything before touching anything. and 2: You must KNOW what is supposed to be happening before you can detect what ISN'T happening! Many times you actually had to diagnose and "fix" the owner instead of the product!
Huge props for Changing the hinges yourself. I was ganna guess you would tell management to find someone to change em.
Feel like people would think “that’s not my job”
Good job man.
Well he gets paid for that too.
@@rdizzy1 Our HVAC supplier carries all the parts for walk ins that others don't have access too. So in my area, the freezer and cooler hinges are still part of my job. We get paid just the same as changing hinges as we do diagnosing a refrigerant related issue.
I've learned more about commercial refrigeration watching you and Rick from HVACR Survival than I ever did in trade school.
Awesome bud, glad to help! Come check out my livestream this evening 11/21/22 @ 5:PM (pacific) and I will discuss your comment czcams.com/video/ez9USkoW54o/video.html
When someone says "Never, forever or always" take it with skepticism.
Definitely thankful For your channel as a upcoming hvac/r tech you give me so much knowledge when coming into the field
They always say they never leave the door open. Can’t argue with dust and dirt on the coil and fans. Some will have dirt built up on the ceiling in front of the fans.
“It’s only open 10 minutes once a week when the food truck delivers.”
That’s what they all say!
Had a lab cooler in a hospital that we installed and the scientist complained that mold was growing in the cooler. Plenty of dust and dirt on the back of a brand new coil. They swore the door was never left open.
When I was involved in the restaurant industry many moons ago many of the stores had cold weather coats for the staff to use when cleaning and loading the rooms. They in most cases had door curtains.
You my favorite page bro, been working refrigeration for 3 months in Los Angeles. A lot of help
great video as always, I'm a junior tech who's fresh to the field and watching your videos alongside riding alongside experienced techs really makes all my experiences feel richer. Excited for when I get to go out and make some of these repairs myself. Thanks for the concise explanations behind what you're doing!
female c a t
I'm not a tech and I still enjoy your videos.
As a career chef. You can tell a lot about a kitchen the moment you walk into the building. from the condition of the surfaces, food/pred storage areas, how things a labeled and dated....the big thing is the walk in.
turn off the walk in. clean the fan blades and blade shrouds. plug a hair dryer in and work the radiator coils with a copper brush. firm, but not enough to damage the system. get the ice off the coils. not only is this good kitchen hygiene, but it will save on costs for not having the HVAC guy come through and the potential of loosing a lot of product.
Business idea: Develop a device that will generate a "door open" report and send results with alarms to corporate. The local workers will get real interested in keeping the door closed.
How long is too long open?
We have alarm at 20 min at some of my client and it reset after every time you close the door
@@SeanReigle I'm sure that can be worked out. Just report at first, and then look to the pattern to set an alarm value. I'd bet the values logged would show a clear cutoff - such as up to 15 minutes to load, or left open for 2 hours+
@@SeanReigle We have similar in the retail chain i work for but its an audio alarm "cold room is open, please close the door" that for is is set at 4 minutes but can be set from 1 to i think 20 minutes and generate logs if you want...
how long is too long... well for most situations... a couple of minutes is more than enough.... indicentally the energy savings from doors NOT being open paid for the alarms in a hurry
That’s a really good idea. But unless it’s a drive-thru alarm most people won’t care too much.
Where I used to work our storage freezer warehouse has a Ke2 controller that is hooked up to a tablet thats in a control panel runs the two tandem century condensing units. It’s nice to have controls at your hands.
I'm surprised the chain restaurants don't require door alarms, at least on the walk-ins. 60s to alarm with a 5 or 10 minute silence button for loading product. Between the energy and cost of iced coils, seems like a no-brainer.
Must of never worked in a restaurant before, the workers will find a bypass in a day
For your remote access question: It uses a Local Area Network (LAN) which is not accessible from the internet. Addresses starting with 192.168. are LAN addresses.
not quite accurate. it still could be accessible if modem/router(or what ever is in the center of the network) is connected to the internet. Just keep that in mind
@@Grauenwolf You are correct. That address 192.168.50.1 can be used on every LAN in the entire world. So even if that LAN was connected to the WAN, you need to know the address of the WAN to connect through the internet.
I like your comparison to a room number. Witness protection breach because they released the fact that the witness was in the kitchen!!!!!
@@mrxions Not true. That requires NAT and port forwarding to be setup up.
@@mrxions I'm afraid you're incorrect. It would require network address translation and the router to be explicitly set up to forward traffic to the LAN address. Even more so, the whole point here is that the URL displays the LAN address which by definition is unroutable -- even if someone would have set up a router that way, it still won't be known to anyone which public address to use. So yes, it's perfectly safe to display LAN addresses in a public video. (i.e. just by connecting a router that has internet connectivity doesn't suddenly make a LAN segment public ;-))
i have to apologise. I didnt know the context. I just replied to comment asuming that the context was "because a device has a LAN adress it cannot be accessible through the internet." I didnt know the question was "is it ok to show a LAN adress in a video"
9:10, had a good laught. Never looked at it this way. 😄
The IP address for the local connection is similar to many store purchased - (except your connection with a two digit difference), local port, (LAN side access) routers. (Not unique or secret). (Many routers these days have an option to disallow remote (WAN - internet) access. Good vid., thanks again.
Our company just went full on Bluetooth on all of our equipment we install. Mitsubishi, Rheem, BOSCH, daikin
6:45 typically any IP starting with 192.168 172.16 or 10. Would be ok to show since those are all private IPs and not on the internet at least without a nat router hiding them.
You are doing a great job instructing.
Thanks for sharing your knowledge.
Yep that was so common on my job also but since all the refrigeration I worked on was company owned with none spoiling pre packaged items I would just shut it down and return the next day or so, lucky me.
Doors open all the time it's like going grocery shopping and watching customers just hold the doors open until they decide what they want you just want to yell at them and say that's why the doors are glass so you can decide then open the door. 😡
In supermarkets, I've often walked past and shut doors that didn't close properly, and the person that opened it just walked off.
Without challenging you on your excellent point, what do you say to those dealing with a door opened less than five minutes ago, and thus opaquely frosted?
One issue with wireless transmitters, and bluetooth is just a short ranged wireless transmitter, is that they sometimes get glitchy when really cold. Mostly when below freezing, but a freezer is just that - below freezing. if they kept it in a small confined area that was mildly heated, then they'd be fine.
You'd think the engineers would be smart enough to check the rated operating range of components before picking them! There's plenty of wireless microcontrollers rated for down to -40°C, though that doesn't help when corporate is telling the designers to save every penny they can
@@Connie_cpu - Yeah, you'd think that, wouldn't you? My father is an engineer (retired). They're often told "here, use this prebuilt module that the sales department said would be the best for this job."
From listening to him discussing the explosion proof packaging he had to design around electronics, those type of robust components are generally very expensive, and almost never "off the shelf".
In a case like this, they'll be using a standardized board, much like you'd find in a bluetooth speaker. - watch some of BigCliveDotCom's disassembly videos, and you'll see a few examples
My buddy is working on getting a gateway to connect to a bunch of wireless probes for the reach in/ walk ins so you can remotely access the Temps. Working on eventually getting it to read superheat and condenser temp remotely as well. Probes are just really expensive
Been good vids to watch. I've definitely learned something here. Thanks bud
Thanks for watching @Bryce Burns
I need to do that with my fridge because water is collecting under the two lower crisper drawers.
when i was a working man i cant tell you how maybe times i had this problem. All the food product would be covered in snow. You spend an hour checking the defrost cycle etc.In the end i would tell the customer you dont have a freezer problem you have a high humidly problem. They would look at me like in growing horns
That green Viper multi pupose cleaner works awsome on fan blades.
OMG, I’ve been wondering the same thing about the wand lol I’ve checked Home Depot and Harbor Freight, but not Lowe’s. I’ve been watching your older vids to see if you’ve mentioned it before, but I never found it haha
Its always the door! Never trust them when they say that
Refrigeration is a nightmare and nobody wants to pay for the headache you go thru
Great video, as always!
I really appreciate the quality beanies. They are very warm and there is enough material to cover down to my neck if needed.
Leaving the door open.... bane of my existence. It's was hot in the store, vendor/ overnight was stocking the cooler and left the door open to cut the chill. I shut the cooler door on vendors daily quite funny actually. That said I work for the c-store.
I wonder why none of these doors have an audible alarm on them which goes off after it has been left open for a couple of minutes. Also it would be nice if some sensor on the door would log this behavior so the technician wouldn't have to guess it.
Worked at a place with the door alarm. Staff ripped it out one day! 😗😗
@@mikechasse1016 Well you can't serve the ignorance of these people ;-)
The world needs more beeps and buttons so the future children can function for the boss.
He said it on numerous of other videos on why they don’t have the alarms
@@Freonleon well, I haven’t had the time to see them all.
Just had a large refurbishment job at macdonalds here in NZ, the loading door is leading to the outside of the building, theres a second door that stops people just breaking in, but the loading operation will take about 1-2 hours to carry out, and in that freezer, there are 2 evaporators to cool a 7m x 4m room, the ice on that was huge, and fast… the new electrical HVAC panel has the controllers hidden from average person view, but the breakers can be turned off, however that still requires a key. Im not sure what the best solution is for what must be a badly thought out freezer. Because i cant advise the staff to just shut off the condensing unit during loading, i did extend the defrost time, and temperature range, but im sure thats not the best approach long term.
No frost on the top of the evap showing defrost works, clear door open warm air leak issue
I'd love to see that generic HVAC/R logo offered on a shirt or two. (If you don't want to offer that, is there any chance I could get the artwork and have a shirt maker I know knock a few out for my own personal use? Being a one man show, I don't have company shirts or any uniform policy.)
The only trouble I see with Bluetooth (or Wi-Fi) between different controllers is that of being in a fairly effective Faraday cage (the metal walls of the box, especially as they are likely electrically grounded, even if only incidentally.) I do find it interesting that the URLs on your tablet suggest that the Modbus protocol is being used internally. They really should change to a display with more capability.
Yeah, I actually don't say anything about walkin cooler doors anymore.... Because it's a complete and utter waste of time...
I can walk out of the building and go talk to the nearest tree.
A lot of the times they'll leave the door open to cool the space or the kitchen area.
Any IP address that starts 192.168 is a class C local subnet. Any device can use those IP addresses but they can’t be routed over the public internet. You have to be connected on the same LAN.
They should invent an incredibly powerful door closer that can break rope and chain and throw in a seriously loud alarm.
It is the URL "Uniform Resource Locator" wrongly called an address. Ron W4BIN
This is why I take pics and videos and attach them to the work order after being told the opposite of what I witness.
6:40 For anyone wondering. 192.168.#.# is a Class C reserved private IP network NOT accessible from the Internet. EVEN IF the controller was connected to the company router which I'd beg to guess it's not additional setup and a special public IP + port number and router configuration would be required to access the device from the Internet.
i dont know if this matters to you but there is a slightly distracting flashing of light might be reflecting light from shiny pieces on head phones because its moving kind of of rapidly on bottom ish part of screen .
About showing the IP adress: Adresses that start with 192.168. are private adresses that can't be used to communicate with the internet directly. For them to be reachable from the outside (ouside meaning outside its local net), they need to use a NAT gateway that uses a public IP adress. This also applies to the range of 172.16.0.0-172.31.255.255 as well as all adresses starting with 10.
RFC1918 private addresses. You can think of them as dialing an extension number on a phone system - "extension 103" only makes sense inside that building. If you dial it from somewhere different, it won't go to the same place.
Best I always hear ia the ice wasn't there yesterday ... :'D
I melt ice for a living too with my Dewards with Ginger ale!!!!!!!!!! 🤣😂🥃🥃🥃🥃
Simple solution. Buy a jacket that will fit most people on the team for inventory duties in the fridge. The next time the door is caught open the person is responsible has to pay for the service fee.
This seems to be a recurring issue. You should get some well made stickers, the ones that can’t just be peeled off and can handle cold temps. Bright fluorescent color, bold letters. * STOP * DO NOT PROP DOOR OPEN - YOU WILL ICE OVER THE COIL AND HVACR WILL HAVE TO COME OUT AND DEFROST THE WALK IN, or whatever 😅
PLEASE PROP THE DOOR OPEN SO I CAN COME OUT, DEFROST YOUR COIL AND SEND YOU A *HUGE* INVOICE EVERY MONTH. LOVE, YOUR HVAC GUY
They will be ice over ;-)
Nice job and video 👍🙌🙌👌😊🍀
I wonder if they leave their refrigerator open at home
They need door alarms to go off when the door is open.
I have the ke2 Wi-Fi tool which isn’t offered any longer. You can connect to their controllers with your tablet or phone. Must have if you work with ke2 eev systems
I've seen this allot. It can get frustrating sometimes.
You've seen something being given out?
Bull, a "hat" has a brim or no brim, a cap has a bill. Ron W4BIN
Great Job and diagnosis, is there another bungie in your truck now?
@hvacr why don’t you install a sensor on the door (that if left open for about 20 minutes) shuts off the defrost unit until the door gets shut again
Come check out my livestream this evening 11/21/22 @ 5:PM (pacific) and I will discuss your question czcams.com/video/ez9USkoW54o/video.html
Was in the beer industry for over 20 years. Yeah restaurant's and bars are constantly leaving cooler doors open.
I didn't know melting ice was a job opportunity, it's much like the electricia changes lightbulbs (what would that be lamps?). Either way with the advent of LED technology it's turned into required electricians work to change fixtures.
Various manufacturers have worked a way around this... driving too few LEDs in a light and driving them near their limit will greatly reduce the life of LED lighting. The other trick is to build the LED lighting into the lighting unit itself so it's not a case of changing a standard bulb, the entire unit has to be replaced.
Hi ! Is there any exact way to calculate the nitrogen quantity for Pressure Tests, for different pressures (like 132 bar or 88bar in CO2 systems). Thank you!
IP addresses that start with 192.168 or 127 make it obvious that it's just a local address to anyone that knows what to do with such a thing. So the people saying that don't know what they're talking about.
Love this channel man 👊is there anyone in Australia doing a similar channel
clog drain can cause freeze u,p's,how much ice do you expect to defrost in 15 min ?
9:09 🤣
Can you show us where you hook your hose up to?
Is it a special attachment that goes onto the sink for hot water
I struggled doing a coil defrost today (top heater wasnt working)
Come check out my livestream this evening 11/21/22 @ 5:PM (pacific) and I will discuss your question czcams.com/video/ez9USkoW54o/video.html
I know that IP address was not going to be externally routable, it's a private class C address. Any IP address that's 192.168.x.x, 172.16.x.x-172.31.x.x, and 10.x.x.x is considered a private address and does not route over the public internet as those address spaces are private class C, B, and A address spaces respectively.
I've heard there are door alarms, but rather than a annoying sound could they be configured to shut off the system? I know people SHOULD just keep the damn door shut, but sometimes it's easier to work around peoples bad habits if they refuse to correct them.
It'd be sort of like those twist timers i've seen you install, but automatic rather than having to rely on people to use it right.
you'd think though that the managers would find a way to get the point across though, if for no other reason than the cost of paying you to come out and fix this crap all the time >
door alarms existed more than 20 years
As mundane as it is I wouldn't be dissapointed if melting ice on hvac's afford me a confortable life. And after that, paragliding, diving etc etc. Where do I sign up?
The stuff I work on won't come out of defrost untill the coil is 55f, also had defrost air switches, so if it comes out of defrost on timer if will go back in untill all the ice is melted.
Maybe having a way to hold the door open during a delivery might be good. You then can somewhat control the bad behavior.
Would be interesting if you made a basic troubleshooting tree or just a list of most common, then uncommon causes for specific problems.
How about a spring delay hinge, one that closes very slow, between 30 seconds and 1 minute? Is there even such a thing?
Time-delay
7:33 cord to hold the door open. Did you remove it? Do you have the power to remove it? Is it put back the next day?
Yes they don't tell you in trade school
How much ice you will melt.
Restaurant world is a self inflicted gun shot of problems most of the times. Its frustrating and easy at the same time. You can get annoyed that you are there for a dumb reason....but at the same time....its easy money. I took all those online classes for KE2 on their website...they have some nice products in their lineup......you were trying to articulate BACnet ( MS/TP )
I agree with the idea of Bluetooth connection. I have spent a lot of time just moving up and down and looking at the manual. From manual to controller and vice versa that it becomes a very tedious task. You like the controller, but you hate the interface, and the customer does not want to spend more money for the LDA. Bluetooth will fix all that.
i feel like somehow that's the modern day equal to selling ice to Eskimos lmao
CHRIS,WE HAVE A SAYING AT WORK/ INCOMPETANCE BREEDS OVERTIME!!!
We don't leave the door open we just never shut it
What about having a non-electrical interface, such as Infrared communication, built in? It may not be quite as convenient as wireless but at least it would anable the use of a decent User Interface. Most modern phones/tablets have bi-directional capability on the charging port so this would enable an IR transceiver to be plugged in, if needed, which would work as a serial interface. It would also remove the need for pairing and the security issues of a wireless connection.
"I have NEVER lied in my WHOLE LIFE, ever"- anonymous customer...
We left doors open all the time when going in and out because there would be a strong vaccum the first time the door is closed. No body could open the door for at least a minute due to the vacuum pressure. Super annoying and caused people to just leave it cracked open when going in and out frequently.
Awesome video buddy I think I would start cutting the bungy cords at them restaurants if they are not listening about leaving the doors open
Why were the fan blades dirty you didn't elaborate? I am just curious.
Once you replaced the hinges, did you try bungie-ing the door open to make sure the hinge springs survived? 🙂
Are they leaving the doors open whole inside because the doors are wonky? When I was a butcher assistant as Shop n Save at they end of their life the walk in freezer and a messed up something that often made it impossible for the inner door plunger to be pressed to open it.
Yeah, definitely wound up stuck in the freezer for like 5 minutes until someone got close enough to hear me screaming for help. … when they tried telling me I couldn’t leave the door open while I was working in the walk-in I pointed out that lack of basic maintenance resulting in an employee being locked in a freezer is likely an OSHA violation and definitely a Union Worthy issue.
I work in a business that has wic and wif and whenever they ice up, is because of leaving the door open, or defrost feature as malfunctioned.
Wouldn't leaving the door open causing icing like that shorten the overall life of the appliance? If so do you tell that to the owners? If I were the owner I would be pissed that my employees were costing me money up front with higher electric bills (during service kitchens are HOT. might be leaving them open to cool off) and increased maintenance costs then down the line with more repairs and early replacement costs. It's hard enough to turn a profit in the restaurant business without careless employees.
They gotta stop leaving these freezers open... that is how you have defrost heaters go bad in the real world.
Only thing I do more often than defrosting is refilling, especially CO2 systems
7:52 you can see where the signs were that said KEEP DOOR CLOSED
Need a temperature log of minute by minute of the temp just by the door 24/7
would it be good to use a heatgun to melt the ice to not make a mess with the water
Love the hat how can I get it in Trinidad
IP addresses beginning in 192_168_X_X and 10_X_X_X are reserved LAN (local area network) addresses. Every device on a LAN likely has one of these addresses, so yes you are correct, it's not useful info to external networks, unless a tunnel has been setup.
10_X_X_X are reserved for LAN, not limited to 10_10_X_X.
192_169_X_X is a public IPv4 address and must *not* be used for internal purposes. If you find anyone doing this, beat them with the IETF/IANA rulebook until they mend their ways. You can get away with using it, of course, but it's a dumb thing to do because things will go badly wrong when systems with these public IP addresses assigned locally try to communicate with a public service that uses one of them. The chances of clashes are low, but I've had it happen once and even had to go nuclear on the administrator who tried to tell me that I didn't know what I was doing, and it didn't matter anyway.
@@nickryan3417 ah, thanks. I'll edit so people don't read my bad info. It's been 20 years since I learned this stuff.
The first "Private" Ip range is 10.0.0.0 through 10.255.255.255
Second is 172.16.0.o through 172.31.255.255 A lot of people who don't live in the networking world professionally forget and or don't know about the 172 range.......
The Third is 192.168.0.o through 192.168.255.255
Those 3 ranges are all Private, and non routable. Meaning, they can not be accessed from the internet unless someone does NAT, (Network Address Translation) to make the device available from the internet. Additionally if they do it, and you are on the internet, you will use a different address to access the device, NOT the private address. An easy analogy for an inbound NAT, would be similar to you forwarding your work desk phone, to your cell phone. You call the work phone, and you get forwarded along to the private IP address (the cell phone.) The only part of the analogy that does not quite work, is with the Networking NAT, the cell phone that gets the forwarded call, is not reachable. So you cant call directly, you have to call the desk phone....
Checked the website, doesn't ship outside America
The employer should charge the employees for de icing .
