I am trying to replace the Honeywell thermostat but when I look at the wiring on the wall, there are 4 wires (G,Y R W). Are these OK to connect to a new thermostat?JA: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?Customer: I've been told that this house has some issues it is about 40 yrs old. I am not doing this to prove any skill issue, I just lost my job last week.JA: Do you plan on doing the work yourself?Customer: If it isn't that tough.JA: Anything else we should know to help you best?Customer: I am thinking that this is a simple-enough for me...disconnect wires, connect new ones (circuit breaker off) then just connecting new wires (circuit breaker back on)

Carrier inffinity is starting to malfunction. Controller

Carrier inffinity is starting to malfunction. Controller turns completely off (non-responsive) and later will re-start itself. Also the blue LED for cooling is slowly pulsing. Trying to look up what this means. Indoor humidity is now 60% and temp is 79 F.JA: I'll do all I can to help. How long have you been dealing with this?Customer: two daysJA: Do you plan on doing the work yourself?Customer: If possible. Laid off so funds are low.JA: Anything else we should know to help you best?Customer: Replaced circuit breaker. I thought it might be tripping since the unit went dead from time to time, but that wasn't it.JA: Did you double-check the thermostat? And what about the unit's filters?Customer: Filter is fairly new (1 month). How do I double check the thermostate, isn't that the control unit on the wall?

Hi I have a Venstar T1700 that just went blankJA: OK. To minimize me, please click the down arrow at the top right corner of this box.Customer: I checked the voltages from the wires coming out of the wall and there is 27 VAC between R and C, which means if it's blank the problem is with the thermostat itself, is that right?JA: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?Customer: That's what I'm trying to figure out. The air conditioning was working the day before the thermostat went blank.JA: Do you plan on doing the work yourself?Customer: If the thermostat needs replacing I'll do that myself. If the wires came loose inside the wall I won't. So I'm trying to figure out which of those happened.JA: Anything else we should know to help you best?Customer: Don Don't think so

I have a Lennox 10ACC unit with a G40 furnace unit. It is

Hello,I have a Lennox 10ACC unit with a G40 furnace unit. It is controlled with a Sure Light control board 10M9301. At times, the unit will suddenly stop working. When I look at the diagnostic lights, both are off. I checked power to and from the transformer and the voltage is correct. I unplug everything for a while (as asked by the HVAC company), but by the time they get there, all is working and they will say 'we can't fix something that is working.' Can you provide a step by step analysis how to check some basic things and provide guidance on what could be happening so when the HVAC company comes again, I can be prepared?Thank you-

Installed Mitsubishi mr slim 36kBTU in our cabin and it was

Installed Mitsubishi mr slim 36kBTU in our cabin and it was wonderful that weekend. The indoor breaker and outside disconnect were turned off when we left for fear of damage by lightning storms. When we came back last night we turned it on and it came on and ran for about a minute. Then The left operation indicator light began flashing. I pulled a manual online and did the error testing to get the code which is a flashing green light and beep at .5 second intervals for three times and then 2.5 seconds off and then repeats the pattern. Does turning off all power to system mess up anything? What is a serial signal error? I'm so frustrated. This is way too expensive to work for 2 days and not come back onRenee and Bill Clark. ***@******.*** or cell(###) ###-#### Thanks for any insight.
