The buzzing may be a bad fan motor you need to see if the blower motor is turning. If not this is your problem. The other thing that may be buzzing could be a contactor. This would be used to engage the motor. To check this take a reading on the coil side of the contactor it should be 24 volts. If 24 volts are present to the coil side of the contactor and the contactor is not pulling in there is your problem.

Frigidaire furnace


is red light on a circuit board? if so that is a error code. look for error code diagnostics on the inside of door(s). tell me what furnace does. first draft motor (small motor) comes on. then you should hear clicking noise and see sparks. or see a glow from front of burners this is the hot surface ignighter. then gas comes on and burners light. tell me what you find. i suggest you turn power off then back on and give it time to start process listed above incase its in lock out mode. tell me what happens.

My Duo Therm furnace was working last night and not this morning


I would make sure there is power to the unit before I attempted any repairs. Gas being available will not allow the thermostat or gas valve to operate if there's no power to them

Multiple clicking sounds coming from AC unit before AC unit turns on or before furnace turns on.


the is a 24v wire that feeds from your thermostat to your unit, inside there is a contactor that engages, this makes a click sound as it really is a basic mechanical part the makes metal touch metal to allow current to flow through the system, perfectly normal, your hearing the low voltage engage the highvoltage at the contactor.

Have you checked for fuses in/at, thermostat ? What type of RV is this in? Power board should need to be replaced again, if at all, my guess is it's something else. Do you hear any "clicking" form unit when you move thermostat to other settings? Is nothing working at all, fan, furnace etc?

Sounds like your indoor fan motor is not working, check either the cap or the indoor fan motor it's self.

What part do we replace first?


Door safety switch. You are sure you have power to furnace? jump out the G and R terminals on the furnace control board or turn your thermostat to Fan On to check. Make sure the door safety switch is in the closed position. Fan should come on. No fan, no power to unit. Check Emergency switch, circuit breaker and there may be a fuseable link in the wiring somewhere either above the unit or a condensate safety switch. Get power to the unit. Also check to see if there is a small fuse in the wiring inside the furnace or on the circuit board.
