Furnace Draft Inducer Dying - How to keep it going for a day or two?


A couple of years ago I had a new draft inducer put in. It's always made a rattling noise when spinning down. Over the last week or two it's gotten worse and now my pressure switch keeps opening right as the gas goes on.

I'm assuming the motor is no longer turning the right RPMs and generating the right amount of negative pressure. I am getting the error code for pressure switch opened.

I'd really like to avoid moving the family to my mother-in-law's for the night if I can help it. Any ideas on how I can get the motor to make it one more day?

Furnace Draft Inducer Dying - How to keep it going for a day or two?


I've tried switching the furnace to do high heat only. That did not help. I guess I am hoping I can oil the bearings to get it limping along for now. Might that be possible?

Furnace is a Carrier Weathermaker 8000 Two-Speed 80% from '91 I believe. Looks like the motor is this Carrier HC21ZE118: http://www.ebay.com/itm/Packard-6511...#ht_1091wt_952

check the squirrel cage for crap and does it free spin either direction...WD40 into the shaft motor area might give you a couple of days... spinning it both directions to work it in...check here for http://www.bestbuyheatingandaircondi...ode=fasco-indb pricing..check Grainger Supply on line for local for overnight shipping...availibility
