    The blower motor on my Goodman Model GU100-3 (S/N 860602118) has gone caput. I am trying to locate a suitable replacement motor. The motor is a GE Model 5KCP39HGM614S. It is HP 1/3 RPM 1075 V 115 HZ 60 Amps 5.50 1 PH Cap 7.5 / 370 Equip Mers #B13400-03. I have not been able to locate an exact match. Can you point me in the right direction?

    After reading some other posts, could the capacitor be the cause of the problem? When the fan is turned on the motor hums loudly but will not turn.

    The Goodman part number for the motor is B134002 1S. Google that. They are readily available. Always replace the capacitor with the motor.

    How much money do you want to spend on that 24 year old furnace? The motor will cost $200 plus or minus, and there will be shipping if you buy it on line because it is heavy. You can get it possibly at a local HVAC supplier, but you will pay retail close to $250.

    You can get a good capacitor tester in the $75 to $150 range. A new cap will run $15 to$30.

    Thanks. I've been gone for a week and just returned to a very hot and humid house. I spoke with a couple different HVAC guys and they directed me to Grainger for a replacement blower motor. Unfortunately it is a three wire motor and the original motor had five wires. Is there some place I could get an original wiring diagram. Or can someone out there give me some assistance. The original had orange purple black red and yellow wires. The replacement blower has only black yellow and red.
