Payne Furnace Blower Motor Problem

[markshew]

Thanks for the words of encouragement!

You said it would be helpful if I could provide a circuit diagram for the furnace, well, unfortunaltely, it is stuck to the inside cover and not in very good shape but I have taken some photos of it and would appreciate you taking a look if you are interested.

The last time I tried to attach a file the system would not let me so, if this does not work, maybe I can send them to you direct?

Thanks,

For anyone out there who is interested, I managed to solve my problem without having to resort to calling in a repair man!

After studying the circuit diagram and doing some searching on the internet, I decide to try replacing the blower motor control board.

I managed to source an exact replacement board from Furnace Parts, Hvac Parts, Airconditioning parts for under $80 including tax and shipping.

Installation was a fairly straighforward task involving labelling and removing all of the connections and from the old board and connecting up to the new board (something that I learned that would have helped me out is to take a couple of close up digital pictures of the connections just to have as a reference).

After making all of the connections, the blower motor worked perfectly!

I hope this is helpful to someone out there.
