Question about Heating & Cooling

1 Answer

I have a Rheem Criterion Gas Furnace. Mod #rcba-24576617 s/n mo494 Even if the a/c or heat is off position and the fan is on auto. The blower fan motor consent run. I must turn the main power off to turn blower off. Is it because the mother board is bad. And if so, could I order one thru your company?

    I agree with this solution. I already troubleshoot the thermostat and know that a relay is stuck close. I was hoping for a parts location.

Actually this sounds like a thermostat or relay malfunction.
As for parts, you have posted this question on Fixya, I am sorry but Fixya just answers questions and does not sell any parts.

    ooops sorry bout that. the best I could do would be our local one hour heating company. But if you arent in Portland Oregon or Vancouver WA I dont think that would work very well for you.. best of luck finding a new relay.

My Rheem Criterion II gas furnace makes metal slapping noise when the blower comes on. It is not the blower or the motor.


Is there noise when the inducer motor comes on? The small motor that comes on first. It sucks the co out of the combustion chamber. It comes on first. Then the burner lights then the blower comes on. And the noise continues while it's running and doesn't stop till the blower stops? Is that correct? But it's not the blower wheel? Could it be out of balance and hitting the blower shroud?

Rheem RHQA Heater:Blower works but no heat.


Is there a setting on the thermostat for Auto or Fan? If so, make sure it is in the Auto setting. You will have a contactor that turns on the elements and a relay for the fan. Follow the wiring diagram to see which relay energizes the fan then unplug it to see if the fan stops.
