I seen most of your carrier video and think 14-16 seer would be more reliable then all these high efficiency system. Also think you’re a great and knowledgeable tech. God bless you
The old all analog two speed Lennox systems were complicated BUT, they didn't break often and if I ran into one and didn't have parts I could almost always force it on one of the speeds until I could come back... That makes you a HERO in mid August Houston,,, lol....
Been having the exact same problem on a Bryant evolution condenser 187 we are getting the proper DC voltage, but I’m getting the 179 fault code. After watching this I’ll run a new low-voltage wire thanks.
What we have here is... A failure to communicate! Some units you just can't reach. So you get what we had here last week. Which is the way he wants it, well.... He gets it! #CoolHandCarrier
Make sure you don't splice the low voltage wires. Remove that pigtail carrier has going to the green terminal block on all units except inverter. Splices creates resistance and will always cause comm errors because of the the low DC voltage that's used for communication. I've been working on these since they first came out and can fix almost any comm fault quickly. May favorite it rust wire nuts outside at the condenser where it's spliced! Use Dryconn wire nuts if you must splice. Also check you DC voltage at A & B comm links. If you don't get 4.5-2.5vdc when connected to the system you have a short. You should have about 4.5 volts DC when not connected to the outdoor unit or control. Also, don't run your wires near any high voltage with out shielded wire. Always check the continuity of each wire lead before tearing things apart. I had a hydronic hest kit relay that was causing indoor and outdoor communication faults?!!?! Go figure. BTW, dont ever break A or B with a float switch or any safety. Use the G terminal shutdown feature. I have a bunch of tips and tricks if anyone is interested. (Make sure you have a GOOD DMM. 90% of problems in.hvac service are electrical related so have the best tools you can afford because your lively hood relies on each.
PatrickNJ Ha that is some good info. Thanks for sharing your knowledge dealing with these infinity system. You definitely gave me a lesson always here to learn and meet new people. Would like to talk to you one day. Can you shoot me your phone 📱 number or email address. My email address is lilfeam@gmail.com thanks
I had a communication problem. I had no COM light, checked low voltage wires from the air handler to the outdoor unit and found to be ok. Checked DC voltage with condenser hooked up was reading 2.8vdc. Changed board and still no COM light. Any suggestions?
Zack Cecemski what i normally do when I run into that situation is run a temporary low Voltage wire just to see if we have communication to the outdoor unit.
PatrickNJ yo bud, I’m having the same fault in this video (179), no communication to outdoor. Tried finding in through the programming to no avail. I’m gonna run a new shielded wire tomorrow to see if that fixes the issue. Please let me know anything else I need to know.
Communication is in dc voltage, but you can check the continuity of your stat wire by tying it together on one end.. make sure the wire is good and move it around while holding each lead with a clamp on each wire... saves you a lot of time
Yeap, resistance is the key due to the comunication in dc varied. Connections need to me 100% and most of wire nut connection change resistance, straight wire is the gooo.
That was awesome, great video. That is exactly what I have going on. Could you just use a normal t-stat an use the normal terminals to by pass the infinity t-stat
Communication is 3 volts dc nominally depending on voltage supplied to the home. When that equipment talks the voltage pulsates up n down. A and B terminals ohm good at 19k on AOC boards.
My neighbor is a Carrier Dealership owner. I went to him needing four complete new units in my 8000 sf house. He said he recommended a Carrier Infinity system and would use it in his own home. $53,000.00 later and two of the four units lost their ECM modules a month after the warranty ran out....( motors good, but the ECM ‘s are around 4-600 dollars ... motor plus ECM is 6-800 dollars ( before labor). I feel robbed. He would not come service during COVID-19 and now that I am out of warranty wants $ $1,200 per unit parts and labor. Sad to say but an A/C license is a license to steal. They know when they sell you these complex systems you are going to be paying them a fortune from now on. I have nothing good to say about Carrier Infinity. All the savings they tell you about on electricity go out the window when you have two $1200 service calls....
I agree with you 100 percent. As an ac tech. I do not recommend these infinity to anyone. They are just trouble. You are better off getting a 16 seer regular unit. You would safe more money in the long run.
Bad neighbor who robs his friend and he doesn't care how much you pay for him. He is happy to accept your money. True friend will tell you the issue of the unit and recommend not to buy. He is a robber.
Gotta make sure the thermostat wiring isn’t against any high voltage wires. The magnetic field from the high voltage causes interference with the communication. Have to move stat wire or use shielded wiring. And make sure there aren’t multiple wires in the abcd plugs.
Hey working on a Bryant Evolution FE4ANB003 Fan Coil fault code 178 indoor Blower Has 240V & 24V at Fuse on board install fuse but no light now on board. Maybe board is NG ? What do you think?
Buying Carrier Infinity was the biggest waste of my money & time over 10 years. Fails at least once a year between bad boards & communication faults that never root caused and fixed. Service folder is 1 inch thick of service receipts. Worst electronics and comms design out there. Should have just used proven industrial RS485/RS422 over these wires. Expect Carrier hires engineers who got C grades in college if they even have degrees. I will never buy their garbage again and tell as many as I can about my horrible experience with Carrier Infinity. The techs that work on them confirm my experience is not unique and none of them would recommend buying it.
I would appreciate your insight as I have searched the internet and read a few carrier pdf's. I am checking out my parents carrier infinity heat pump and air handler to reduce heating energy consumption. When I checked usage data and the equipment sensors in the infinity touch thermostat (B series, software version 3.60), I don't get all of the information. I get the electric heat element, but don't get the heat pump kwh or $ usage. On the indoor unit, it shows model, but doesn't show a serial number ------, (software ver CESR131329-17). On the fan coil status I get n/a for the leaving air or indoor coil temperatures. I was told a circuit board was replaced 2 years ago, but I don't know if it was on the indoor or outdoor unit yet. How do I get the thermostat to display the missing data? thank you. Recent Error codes: 160-Humidity sensor fault (10x), 75-inverter out of range(1x), in September 56-OAT-OCT thermistor out of range (101X)
I would like to know if anyone has a direct number of Carrier Corp. I have had Error problems from the time my Infinity Unit was installed and the dealer here are unable to fix any problems they just change a part then charge me labor. Errors 37, 45, 178
Hi can you tell me what the dip switches should be at on a new carrier 59TP6 100k BTU furnace I have a ecobee and my installer just left it at the factory positions and told me to leave fan on all the time.Thank you
Nice video. Great troubleshooting, always good to think outside the box. Keep it up.

Yep it's usually wiring. I want to start playing with a oscilloscope to be able to see a communication waveform and know good from bad.

Interesting find. Thank you
As a former A HVAC tech, I would never install a communication bus system in my home.
me either! more digital BS more problems!
Good vid
Love the Trane hat :)

It’s been our experience that Carrier Infinity Systems need shielded thermostat wire.
Hope this helps.

fieldpiece mike thanks for the comment.
My issue is that the outdoor fan doesn't run. There is no DC volts at the blue and yellow variable speed plugs.
Thank you so much

Anyone have the touchscreen calibration off so badly, it no longer will go "back" or "feature" or "menu"?
I have the same problem now I can't get to work at all
I would like to know if anyone has a direct number of Carrier Corp. I have had Error problems from the time my Infinity Unit was installed and the dealer here are unable to fix any problems they just change a part then charge me labor. Errors 37, 45, 178
I’m getting a 48 code. Help!!
Am getting error code 180 ?
The electric switch next to stat is a problem
so short cross?????
What was issue? Communication wire from furnace to outdoor unit?
Hey, thanks for the response. We had to replace the outdoor communication wire. After that, we had a communication with the entire system.
Hi can you tell me what the dip switches should be at on a new carrier 59TP6 100k BTU furnace I have a ecobee and my installer just left it at the factory positions and told me to leave fan on all the time.Thank you
Crummy infinity thermostat user interface and the app is worthless as well. Don't waste your money! Thousands of poor reviews can't be wrong
