BLOWER CONTINUOUS
Rheem · Rheem R96V 96% AFUE Two-Stage Variable Speed Upflow Gas Furnace
The indoor blower fan runs nonstop and will not shut off. First check the thermostat fan setting — it should be set to AUTO, not ON. The ON setting runs the blower continuously regardless of heating/cooling demand. If the fan switch is already set to AUTO and the blower still runs continuously, the fan relay on the IFC board may be stuck closed, or the thermostat G (fan) wire may be shorted to the R (power) wire. To test: disconnect the G wire from the IFC board terminal strip. If the blower stops, the problem is in the thermostat or the wiring between the thermostat and furnace. If the blower continues running with G disconnected, the fan relay on the IFC board has failed and the board needs replacement.
