- Today we look at a package unit that isn't cooling and keeps dropping our low side voltage. I'll admit I was more confused then I should have been but in the end I won. Enjoy-

Also keep a lookout for return dampers closed on some fire systems. Sometimes the whole roof is wired to one dry contact at the fire panel, locking everything out for 1 fault somewhere.
Soon as you said many units down, I thought fire alarm. Good video
Lee Johnson yeah, smoke alarm, fire alarm or some duct pressure sensor system.
Great video---Im a new subscriber---I appreciate when someone is man enough to admit he overlooked something or didnt see the issue immediately--thats how we always learn for next time
Absolutely, repetition and knowing sequence of operations cuts out a lot of wasted looking.
If you're anything like me, I seem to ONLY learn and remember through struggle, pain, etc. :-) Great job, and thank you for the video.
Really good analysis, and patience on your end, solid troubleshooting thanks for taking me through the process 2 thumbs up
Good one! 👍 I really like your thorough & calm procedures 👌
Hello sir big fan here from Minnesota, , just started watching your channel a few weeks ago, thanks for all that useful information. I like the way you explain things and explain what each wire does and what every control board does and all that stuff, you go deep in to the important stuff, I also like that you go straight to the point and also never make a video extra long by telling us about your personal life and bla bla bla lol anyway thanks for helping a lot of us become better at this trade I look forward to watch more of your videos and learn more. Thanks and have a great day!
great video, like the way you keep your cool while trouble shooting & explain your thoughts as you move along. Good job👍
Well , I learned something today , just by watching you go through the trouble whilst sitting on my arse !
Cheers for that 👍😅
Awesome catch. Love watching the videos and keep them coming. Thank you
Let bonded filter company know they need to fix there pleat insert filters. Good video
Yes sir- thanks for watching
Great vid brother.. awesome channel im happy Chris at HVACR VIDEOS threw your channel plug in his live stream on Monday. I can’t believe you never came up in my algorithm before that! Good stuff!!!
This cabling is a mayhem. The americans do not have any honor when it comes to cabling. This is a terrible way...
Solid troubleshooting. Nice walk through.
Definitely learning a ton
Thanks so much😊😊
Nice job, I have this same problem and as soon as i started to look into the smoke detector it started raining so I didn’t get to finish. I thought i was crazy too because the board had power but wasn’t flashing any lights.
Great video Curious h v a c we had to wire up a three phase motor starter with overload and three phase monitor protector in the lab it was a good learning experience. Awesome content love the channel thanks for all your knowledge.
Thanks man
Good job dude where to go Mr. troubleshooter sir my salute sir
Thanks for this. I have a ton of York’s for my McDonald’s I take care of this helps out a lot having a similar issue
Good job bro thanks for the walkthrough
AWESOME SHIT! thanks
Sounds like some old Bristol’s but still a lot better then the LG shit we put in today.
They should have been getting a trouble alarm on the fire system inside the building .. next time your control circuit is doing weird stuff I bet the smoke detector will be the first thing you look at - corset all u have to do is check for that 24 volt input from the smoke detector...
Thats exactly right, next time I hope my experience with this unit kicks in and I get it diagnosed much faster- thanks for watching
Vinstar monitored!
yes sir
A way to check a short is pull all wires off beside incoming power and plug wires in one by one until it short/board shuts off
Good 👍 job
Excellent Trouble shooting.9/15/2021
Good job
When one leg of three phase power goes directly to compressor, this is a trickle circuit to warm compressor windings CCH
Thanks - I appreciate the knowledge
I sincerely hope you are joking.
Just FYI smoke alarms have a tamper switch on them ,the cover has to be on to work correctly ,and reset
Interesting- I did not know that, thanks for the tip
@@curioushvacguy6876 Now I'm curious, wouldn't the duct detector being in "alarm" at least have triggered a trouble on the fire alarm panel?
Nice job
Thanks boss
Those damn smoke detectors!
The 2 flash is start up delay. If you hold test button for 3 sec it will bypass the delay
That would be one of the 3 black buttons on top corner of board
Thanks for sharing 👍
nice video. I say that same thing when that happens to me. no instant gratification. because it still feels like a guess. lol
Good catch!
Those blue filters in front of the evaporator coil look woefully inadequate. They look like glorified coffee filters. Nothing like I've ever seen before, but I'm a design engineer, not a field tech. What do you think?
eggman9713 you’re right
10:45 nice find plus Air filter is like useless it's the cheap It Looks Like paper crap that doesn't flow good enough
great job
Thanks
Your a bad arse. Well done!
Good find
Super
damn good content brotha!
Thanks
Hi, my york rtu unit is in heat mode and giving a HS1 limit switch error on the smart simplicity control. I've checked the high limit switch and it seems fine. The manual for the control says the LS1 has tripped 3 times within an hour. This results in the HS1 LIMIT SWITCH LOCKOUT. Any help would be greatly appreciated. Thanks.
Was it the same issue in the second unit as well?
Look at the back
Of the board damn, it’s so easy
👍
You have
Bit of an overly complicated phase monitor.
Agreed
