No Heat - Inducer Motor ? Payne furnace

Post by bhclark1234 » Sun Dec 23, 2012 9:35 pm

My furnace crapped out today. It starts up, calls for heat, but nothing.

It is giving me code 31.

After sanding the ignitor and thermocouple I realized the blinking was an error code.

I was finally able to spin the inducer motor by hand and it finally started spinning and fired up. Not sure how long that will last.

I'm not sure if I can find a parts store in Cincinnati/Hamilton Ohio that is open tomorrow, on Christmas Eve, but if I can and they have the part, how difficult is the replacement and will the fan come with instructions?
I'm hoping they will sell to the public.

A quick Ebay search came up with a Carrier part number 318984-753 for $105. I'm sure it will be twice that much locally, at least, but would that be the correct part?

The unit is 14 years old...I would replace it if I could afford to. (I know, as inefficient as it is, how can I afford not to...)

It's very cold this week.

Any advice would be appreciated.

If you find the inducer motor shaft does no spin freely, as is implied by your description, try dripping 3 drops of 3-in1 oil at the base of the shaft and let it run into the motor bearings. If it's difficult to get at, try spraying a little WD 40... anything to help lubricate the bearings.

If you can remove the motor separately from everything else then possibly you can find a replacement motor. To replace the entire inducer, be sure you have the correct part number. A local HVAC supply house may have it or can order it. Also check for local Payne dealer.
