I woke up this morning to a very cold house. The thermostat was set to Heat, and it was running and blowing air, but it was not hot. I turned the thermostat to cool, and the A/C turned on. I went back to Heat and still got no heat. Just the fan blowing cold air. I turned the thermostat to the...

We recently removed a counter-top peninsula which had baseboard heat on the backside. I have moved the location of the baseboard to the opposite end of the kitchen, which made more sense to me anyways as it is colder on the exterior wall side. I tied back into the original location where the...

My honeywell wifi thermostat went blank while my heater was running yesterday and now my unit just blows air (no heat) and I can't shut off the unit unless I unplug the York furnace. Here's what I've checked so far but still can't figure out what's wrong and the cause of my blank thermostat...

I have a Trane XC95 furnace that's 14 years old and intermittently stops heating. When it stops heating, I get a 3 flash code indicating a pressure switch problem. It does not present an error code at the thermostat. If I crack open the burner box and remove the cover, the furnace runs...

Hello, I have a Lennox Signature Model G61MPV-36C-090-09 furnace. I was noticing that it was not heating the house when it started to get cold. I turned it on and off at the breaker and observed that it would ignite and blow flame but the blower fan would only rock back and forth, never...

I've got a 100-year-old, 3-story house with a gas boiler, 6 zones, and many radiators. Three on the second floor do not get hot. They probably are in the same zone, but honestly, it's hard to know where all the pipes go. The boiler is working. All Thermostats are working. Air in the radiators...

Hey Gang, First time poster here. Went to fire up the heat for the first time this season yesterday, and after 30 minutes I noticed it had been blowing the whole time, but there was no heat. This is a model number GUI075A012AIN. Taking a closer look, I saw that I had three blinking lights...

Hello and happy new year! since coming back from vacation, my hvac is not blowing HOT air anymore. everything was working fine before. it's blowing air now, but just when we increase the temperature, it's not producing HOT air. the thermostats are OK (they're all new from sep 2018), and...

I have a Trane XR90 furnace that is periodically not igniting. I get a “pressure switch” error (three blinking lights). We have had the issue in the past, but after shutting down the furnace, waiting and turning it back on, it would work normally. This winter, the error has been much more...

I think I have a bad circulator. I have 120 volts going to it. The light for zone 2 is on so i knew the thermostat was sending the message. I check voltage at 120 past the relay going to the circulator and took the cover off the circulator and got 120 there too, but it's not sending the water...

I have a Goodman GMT070-4A. When turning on the heat this year (I live in San Diego), there is no heat coming out of the vents. When turning the furnace on, the ignitor will glow, the burners will ignite then will run for about 6 seconds then shut down. This process repeats three times then the...

I have a Carrier (Model 80U-19A) furnace from the mid-1970s that is not working. When the thermostat turns on, normally the flames ignite and a short time later the blower kicks in. However, the flames are not igniting, now. The blower still kicks in after the usual wait period. It is a...

The heat in my home does not work. It cools just fine, but when I turn on the heat, it doesn't do anything except blow air. I've had the unit since 2007, and the thermostat since 2011. Yes, I have it set for heat. Yes, I've checked the circuit breakers. Yes, I set the temperature for 5-10...

Hello folks, I recently had to replace the control board on my furnace. (N9MSB) The board I purchased is identical to the original. (OEM 1184594) I received it in a new, unopened condition. No physical defects to be seen.. So I swapped the board out and took it for a spin.. I ran it through a...

So we are in the shoulder season here in Georgia where we jump from a little A/C in the daytime and occasionally have the need for heat at night. The other day we noticed that the air coming out of the vents with A/C on smelled a little musty. It was not not quite like dirty socks but not quite...

I have a Lennox 80UHG furnace that quit working yesterday. I can turn the blower fan on by switching the fan from "auto" to "on" but the heat will not kick on when the thermostat is set to "heat." I have the temperature set above ambiant room temperature but nothing happens. There are 2 green...

Hello guys and gals, I have an old york diamond 80 furnace that was not running when started the first time after the summer. voltage was being supplied where it was supposed to be, the call for heat was there, but it wouldn't even begin to turn the inducer motor. A couple times, when...

Hi, we bought a house with a heat pump and an electrical furnace as auxiliary heat. Unfortunately this winter we noticed that only the furnace was working to heat the house. The temperature was a little bit warmer today so I decided to run a couple of tests on the heat pump (Carrier 38YXA) and...

Our furnace stopped blowing heat a couple of days ago. Forgive my lack of terminology but here is the scenerio. 1. thermostat clicks 2. inductor? fan runs 3. ignitor glows for 5-7 seconds and then goes out. 4. no ignition, no flame, no heat= we're freezing our butts off. Easy to assume that...
