Lennox Air Handler Fan Problems
I have a Lennox 80MGR that is in series with my refrigeration coils and serves as an air-handler. The fan suddenly stopped working yesterday. I obtained a new condenser and replaced the old, and that did not help. I see one red LED on the control circuit board, and it flashes slowly and steadily. I have read on this forum that sometimes the LED flashes a count to signify troubles, but that doesn't seem to apply here.
I would like to bypass the circuit board to see if the fan will run. I could also replace the control board, but if the fan motor is bad, I hate to throw good money after bad!
Any suggestions wouild be appreciated.
