Question
I noticed that my blower was not turning on after I turned up the heat. I hear a clicking noise like it is trying to blow warm air. The furnace heats up. I have it off now. I have a Nordyne manufactured air and heat pump (4 speed blower 4 ton 2.9 FLA 1/3 HP). Please advise. Thank you
Answer
I am not sure about the type of unit you have? you said heat pump, but said the furnace heats up? a heat pump has no gas unless a rare type of multifuel using I have seen only several times.
but the fan operation regasrdless is similar in that the heat speed /low is controlled by time and or temperature, generally heat pumps are time initiated and time terminated as there isnt anf flame that runs to warm up the temperature delay type of controller.
does the fan run when fan switchis set to on? probably not. either run capacitor if lucky or fan motor and or relay, if a circuit board controls fan I have piggy backed relays onto boards that the fan relays have quit on rather than $400 for a board if thats what it is.
