I have been having an intermittent Rheem air conditioner/ heater problem. The blower won't shut off unless I cut the main power. The furnace shuts off fine. Switching off the fan or anything on the thermostat won't shut it off. The technician says that they won't repair it unless they find it dead. By the time the technician arrives the AC is working again because it usually fails at around
1-4AM then resumes working again at 5AM.I am now deciding to replace the parts myself but need some help. I'm not certain but I think the symptoms point to the blower relay D7 or the fan cycle control switch F7 on this schematic diagram
Where is the fan cycle control switch is located in the Rheem heater - is it inside the furnace?
Thanks Tim
