I have a Rheem Corsaire model #FGPJ-10NBRJR with a serial number of EB5D307F389707624.
My airconditioner & heater operate fine when I use them. My problem is with my thermostat off, the draft blower motor on my heater cycles on & off continuously every minute or so. It turns on for about 15-20 seconds, then turns off for about a minute, and repeats. The relay on the circuit board (board model 1012-925A) that I think is "clicking" on the blower motor is the second in from the left (small Siemens relay #9651). It clicks, the motor starts, it clicks again the motor stops.
Any ideas? I have a meter and can check themostat switches, etc. but I do not have a diagram to see if the should be open or closed, or what voltage, etc. I don't want to buy a new board for $100 if it is just a $10 limit switch!
PLEASE help, and thank you in advance!!
