I have a very old gas, forced air, Luxaire furnace model #GH102SE and am trying to limp through one more winter season.
The blower motor can not turn the squirrel-cage fan. I can manually move the fan belt and the fan easily turns. But when the motor receives the signal to start, it jerks the fan belt and fan into action but immediately everything stops and the motor makes a buzzing sound. I've tried to manually move the fan belt when the motor is making the buzzing sound and it feels like the system is frozen.
The motor is about 10 years old and I replaced the fan's axle and bearings last season, beginning of 2009. I also replace the original thermostat with a Honeywell digital thermostat last year. The pilot light seems to be functioning properly and the burners ignite and stay lit.
From my description does it sound like the motor is bad? Should I disconnect the fan belt and see if the motor can turn? If it does what would that mean?
Any help would, of course, be appreciated.
