I have a 15+ year old Keeprite Furnace that wouldn't start up. On investigating, the limit switch is tripping due to the blower motor not powering up.
It seems to be getting power, just measured with an AC pen.
Pulled the blower motor, Emerson model M55BMCNR-216. It's a 4 wire motor, with Green, Blue, Yellow and Red wires.
Resistance from green to each of the other wires is O/L, so open.
Resistance between Blue, Yellow and Red are all below 10 Ohms.
I'm assuming that the motor's fried due to the O/L between Green and each of the other wires, but wanted to see if anyone had any experience with these motors before I spend the money on a new one.
Thanks
