    My furnace keeps turning off and losing power to the control board. The control board lights are off. One time I cycled the power and it powered up. Haven't been able to do that since. So, I replaced the transformer which worked, but it started happening again a week after the replacement. I...

    Hi, I am a new home owner and I have a Lennox elite gas furnace. There is a black box on the side which I beleive is a condense trap? There are 2 valves, a drain valve at the top that has a cap on it and a clean out valve on the bottom that is an open spout (no cap). I have lived in the house...

    I have a generator wired into my breaker box via a transfer switch to power various circuits during a power outage. Yesterday I got to test the system during a power outage. Everything worked fine except the Honeywell Wifi thermostat, which did not have power. I have the furnace wired to the...

    I have a 30-year-old Coleman gas furnace heater located in my attic. Lately it had been shutting off too soon, before it had reached the temperature I set on the thermostat. It also seemed to take extra long for the blower to come on after I turn the heat up… Sometimes five minutes or so. When I...

    Hi all, I've been having an on and off issue with my oil furnace for the last year or so. Every now and then water would slowly drip out of the copper pipe pointing down towards the ground (open on bottom). I'm guessing this is some sort of pressure release system? My furnace guy said it's...

    Hi everyone, I have a 3 yrs old 52000 BTU efficiency furnace. It was working perfectly for the first 3 winters, then started behaving weirdly just about a month and a half ago. I would set it to 74, and it USUALLY would not kick in until the temperature would go down to 71, 70, sometimes even...

    I would like to disable second-stage heat completely on my Carrier furnace. How can I do that? Why? => My Carrier furnace often goes into "limit switch fault" and then "limit switch lockout" (more info below). I'm pretty sure this only happens when switching into the second stage and I want...

    I have two of these and yesterday and after two days of 59° in the house I decided to take a look. We are also supposed to get a deep freeze tomorrow so that was motivation in itself. I was able to get the downstairs furnace working by cleaning the flame sensor and thermostat. The upstairs...

    I have a 13kw electric furnace that's been setup for 2 stage heating where the thermostat controls each sequencer. It has 2 6kw elements with a heat sequencer on each one (both on for high). Problem is after both elements are on for a few minutes there's too much heat behind the sequencers for...

    Hi, I have a Goodman GMS 90703 BXAA furnace in my house. Last week I turned the thermostat on heat for the first time this year and it worked fine for 2 days. Then suddenly the heater shut off, the air blower stayed on and the error code was 6 blinks (open rollout). I did some basic...

    Hi all, Today my air conditioner stopped running in the middle of the day - we have an HVAC unit outside, central air, and an electric furnace. All controlled by the thermostat on the wall. Thermostat was blank, nothing on the screen, and unresponsive. I opened it up, but no batteries, just...

    I have an old furnace that is not working properly, a Carrier model 58SE150-3 series 314 from 1975. I have diagnosed the problem to a likely fused fan blower relay. In looking over some of the other forum posts people seem to recommend that I not replace the relay directly (a Potter and...

    Hi, I have a Carrier 58CVA/CVX furnace that is turning off. I called a repair man and he tried to pull codes and diagnose but couldn't find the fault. I would like to be more certain before spending $$ for a new motor. Any help is very much appreciated. Here's what it does: In the spring and...

    Electric furnace shut down about 3 am, wont kick on since. I have checked breakers, the internal fuse, they are all good. I checked the thermostat, put new batteries in it, and even bypassed it by putting the white and red wired together. I get absolutely nothing. It would click when it started...
