Adding oil to draft inducer/booster motor
Posted: Sat Oct 11, 2008 11:34 am
I have a few questions re: the draft inducer/booster motor, so I thought I would combine them all in one post (hope everyone doesn't mind).
I have a Coleman presidential II model, and the motor p/n is 770-8314 (the approx 8 inch cylindrical black motor).
1) Before I call a repair man out, I wanted to try to oil the draft/booster motor first to see if that helps. The furnace was fairly dusty and I just finished vacuuming and dusting it out.
I see 2 metal "spout type" projections coming from the motor, and the bottom spout is titled "oil".
So what type of oil do I use, and how much do I put in there?
2) Also, I read in the quick tech tip guide how to "hand spin" the draft inducer/booster motor first to see if it "sticking" was the problem. How do I hand spin the motor? Do I just turn the metal rod coming out from it?
3) I looked at the parts prices on this website. I notice there is a booster motor with and without the assembly. How would you know if you need the entire assembly, vs just getting the motor w/switch?
Any info would be greatly appreciated. I really think the problem is either with the motor and/or the switch inside (since I believe my father, who is licensed HVAC, before he passed said the motor is going out when this happened to my furnace a couple of years ago.
Thanks!

BTW, this website has been a Godsend! I, as I am sure others too, thank you sooo much for all the advice!
