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.
Although it can not be determined without first hand observation and diagnosing it, sounds as though your blower motor is...toast. Given that your current model is late 70's I would have it checked by a qualified technician to make sure repairs are feasible. If you have been thinking about replacement now may be the time to put the plan in action.
