inducer blower motor Noise
 
My inducer motor for my home furnace is making a high pitched noise. They HVAC guy came in and said that I need a new inducer motor assembly. Is there a way to tighten the pre existing assembly to reduce the noise. It seems when I put pressure on the motor, the noise disappears.

Does is seem that the inducer motor needs to be replaced? Would tightening the motor make a difference on on the assembly?

Thanks!

give the area between the squirrel cage and where the shaft goes into the motor a couple of shots a WD40 with the extension tube.shaft might be rubbing on housing reposition squirrel cage...make sure the squirrel cage round fins are clean.

If, a few days after tightening, the noise returns, yes.

I only have access to one side of the inducer motor. Would spraying WD 40 be enough if only sprayed from one side of the motor?

Picture attached.

Unlikely.
Get a nutdriver, power off, take out the assembly.

Or rig up some coat hanger wires or some kind of fixture to press the motor into a direction where the noise goes away.
It's a kluge but it may work for quite a while.

Your only symptom so far is noise, and pressure seems to fix it.
If the noise means metal-to-metal contact it may also grind down and cure itself, but don't hold your breath.

thanks. I have pressure on it now, seems like a temporary fix.
