Hi all, I have a 6 year old Trane XR80 furnace that will not stay lit. It will light for about 2-3 minutes than will go out. It will stay out until the system is turned off for a significant amount of time. The filters are new and I have cleaned the burner parts. What other things can I check?...

I have Trane XR 80 model gas heater. For last week or so, fan keeps running even after reaching the set temperature. Its switching off the heater but fan keeps running. Not sure how to debug this issue. I tried changing the thermostat but no change. I could'nt find the manual online for this...

I have a Trane XR80 furnace. The furnace works fine sometimes, and other times is will not light. I get no error on the LED indicator on the main board. The ignitor gets hot but the furnace will not light. It appears that there is no gas getting to the burners. Any suggestions would be greatly...

Sorry in my last question I forgot to list the model of trane I have. Its Trane XR80 and the furnace cuts on and off a few seconds apart. The red light blinks 2 times. Any suggestions? Cold air here

My Trane XR80 furnace is only blowing cold air. The diagnostic light is bllinking 6 times which, I think, means the 115 volt polarity is reversed. Is this something I can fix or do I need a repairman?
