Hello to all,
I am looking for some feedback/suggestions regarding my Trane XE 80 furnace. The furnace is about 22 years old and running strong for the most part
. About 4 weeks ago, my furnace would heat intermittently ... might run fine for a few days and then stop. After a quick reset, the heat would come on and all was well. I decided to change the filter, clean the flame sensor, and check the thermostat (basic digital Trane thermostat w/o batteries).
Everything was fine for until this morning when I noticed the heat stopped again. This time I check the status indicator before attempting to reset the unit and noticed 2 flashing lights which tells me 'System Lockout (no flame) / check polarity.'
I reset the unit and see the call for heat using the status indicator (fast flashing light) ... I see the ignitor light up and hear what sounds like a switch which I assume is the gas kicking on ... the ignitor stays on for about 10 seconds before it turns off without lighting anything. This happened 3 times and then it locked out again. I toggled the gas switch off and back on and lightly tapped the box that holds the switch. After hitting the reset switch, everything worked as expected.
I am not certain what to make of it. I suspect a faulty board/switch? I appreciate any thoughts. Thanks! :biggrin2:
