Question about Heating & Cooling
Got a problem that just started to appear lately.
Typical operation - thermostat turns on, flame turns on, fan kicks in.
Problem now is, that the fan will run for about 2 minutes or so then shut down. This will happen two or three times before it remains on and continue to run until the set temp. is reached. I never lose the flame during this time. I have also noticed that this problem only seems to occur in the morning on initial start up. It seems to function normally once it has ''warmed up'' so to speak.
The thermostat (Honeywell) has been replaced for observation - no change.
Thoughts on where to go next? relays, timers, blower fan cap?
Model: Rheem furnace RGDA-100E-GR (100,000 BTU, natural gas)
Hi check out the fan control switch could be dirty itsounds like this is nit cutting to let fan run also check setting fan off fan on , temp rise and fall
