Question About White Rodgers Thermostat 1F80-224
IF80-0224...

Heat will come on for 10-15 minutes and then it starts to blow out cold air. Need help on how to fix this. I tried reprogramming the thermostat but no luck!

0 I may be wrong but I believe 1. the wall stat calls for heat 2. the burner comes on 3. a stat in the furnace plenum waits for the heat to build up so you don't get a blast of cold air then turns on the fan 4. the wall stat reaches setting and shuts down the burner 5. the plenum stat waits until the heat in the plenum drops to a comfort zone then shuts off the fan. Sounds like that last setting of the plenum stat is too low. Pardon my non-technical jargon.
