Can someone tell me what part number and where I can get a replacement inducer motor on a Rheem Criterion, circa 1992, model RGDG-150ARJR? Already had someone come out and said ball bearings were going bad and motor should be replaced. They wanted to charge me $400 for the motor alone. I see motors on the internet for about $150-$250. I just don't know which one to order. Grainger is in my area and they don't sell Rheem furnace parts.

Take the motor out,, take it to Grainger,they should be able to match it with something,that will work. Just make sure its very close to the same rpm`s ,same voltage,and runs in the same direction,, get a new capiciter for the new motor

And ofcoarse will mount correctly

Woops,, didn`t notice that you was looking for a inducer motor,, so strike the part about the capiciter,, but I`ve been very lucky on grainger finding motors
