Heil Furnace troubleshooting


Model #NUGK075DG07 - 867.769426

There is a thread on site here that I came across while doing a little research.

Here is the thread- Heil furnace inducer vibrating, capcitor handling question

I attached a pic from that thread, same exact thing as my sisters.

Just for a quick breakdown from what I have learned, to make sure I am correct.

The inducer is the first item to kick in, in the fire up sequence. It provides induction of air flow to provide the combustion process with oxygen. If it does not operate, nothing else will fire up, including the flame.

Situation-

Blower fan operates. When T Stat is turned on, the induction fan motor hums, I am assuming it is seized up. It did get hot when I investigated the problem. I do not know how long it was left on prior to me doing my investigation.

Questions.

Is there a way to attempt to turn this fan to see if it is a seized motor?

Is there something else I should check after investigating this? Meaning, could this of caused any other damage?

If determining this is the problem, where do I find this part? My location is central Wisconsin.

Thanks for any help.

Alright mods, you can close the thread.
I took the induction fan out and took the fan body apart. Somehow a little chip of wood about an 1 1/2" long by about an 1/8" thick got inside. This was enough to make the fan bind against the body and not allow the fan to start.
Whoda thought.

I am a Heil and I would question how a piece of wood go into the blower to jam it.

Also breaking the seal on the blower body renders it unreliable after reassembly because the gasket is broken, and there is no kit to fix it.

The odds are extreme a piece of wood was a fault....there just too many barries the would block the wood before it even got near the blower assembly.

Good Luck and go buy a new motor.
