Hi,

The other day I noticed a burning smell in my house and that the front furnace in my house wasn't working. It's a Trane 58RAV075-JC natural gas furnace from 2002. I haven't been able to find a manual for it online.

I've been doing some research and it sound like the fan motor itself has burned out, I think usually the bearings seize. It makes a loud hum if I turn on the fan, like a solenoid trying to engage. However, it doesn't turn. It does seem to turn quite freely when I rotate it by hand. Any ideas besides the fan motor that would cause a loud hum and the fan not to turn?

I noticed there was a lot of white looking sealant around the inlet to the fan. I assume this stuff is to seal it, since it's on the suction side of the fan. It kind of looks like grout or spackling or something like that. It looks like I'll have to break this seal to get the fan out, assuming the fan is the problem. Any idea what this stuff is? Would high temp RTV work to seal it?

-Eric

Are you talking about the fan/blower that moves the air in the house. Or the inducer/combustion blower.

If it is on the door you have to remove to get the fan out it may be white silicone. People sometimes seal the door if it is leaking air and whistling. Ordinary silicone is OK.
