I have an old Rheem gas furnace. My fan blower motor stopped working. I had Sears order me a new one. The installer walked away, giving up because he couldn't get the old motor out of the housing. I got it out and installed the new one myself. Everything turns freely. I made the furnace turn on and all that happened was an electrical hum when the blower motor was supposed to turn on. I turn the power back off because I don't want to fry the new motor. The electrical connections are the same as the old motor. What else could be going on?! Could there be a relay somewhere that isn't working or something else?
It was hard for Sears to find a motor for me. If there is something else wrong that needs to be replaced, any ideas where I could find the parts?
Anyone have any ideas?
