Last night I noticed a strange smell coming throught the ducts. Best I can describe it's similar to wet wool mittens drying on a radiator. Took a look at the furnace and noticed the blower was not running, althought I could hear a humming apparently coming from the blower motor. I tried to spin the squirrel cage but could only get about a 1/2 rotation or so. This could be due to its awkward location or cause of the problem(s) at hand.
I tried again this morning, after noticing the humming seemed to cycle several time since I first noticed it last night. The motor still feels hot. The unit is a forced air gas Coleman, possibly of late 70's construction.
Tried searching online and here in the forums but not having any luck so far.
Any help or advice would be appreciated.
