Hi,
I'm having problems with my furnace. The thermostat works fine because it
keeps calling for heat. The Pilot Light and burners work because they kick
on. When it "seems like" the blower should turn on nothing happens and then
the burners turn off again. This is a really old Flame Master furnace,
pretty sure the company isn't around anymore. Does anybody know where I
can start to trace the problem? Is it the motor itself (I can turn it by
hand and it spins no problem)? I'm at a loss as to what to do and I live
in a very small town and all the furnace guys are booked untill the new
year so I have to try to find a solution myself.
Any help would be appreciated.
Kevin

There is probably a temp switch above the burner which controls this.
Check it.
If you have a switch for "fan-only" operation, turning it on would
probably get you heat.

The older furnace blower motors had reset switches on them, the motor
is not starting and that might cause your blower switch to hit high limit,
and
causing the burners to shut down. The motor starting switch might be bad,
the motor winding are shot.

What I'd want to know is if the motor is getting power. If it is,
you've got a bad blower motor. Or a bad run capacitor.
If the motor isn't getting power, I'd be thinking fan limit switch.
Or, fan center.
