Payne Heater Problems
Have a 15 year old Payne forced air heater, model 373 LAU 048115. So far, to keep it running two years ago I replaced the circuit board and last year the inducer motor. Turned the unit off for summer and restarted yesterday. Fan comes on, then inducer motor, but igniter will not glow. Receive error code 31. Tried the test mode and everything works fine including the igniter.
Have inspected the exhaust vent and there are no obstructions. Bypassed the pressure valve below the inducer and still the igniter will not glow.
