    Question Replacing Motor on Frigidaire Dryer FSG747GES0

    I am replacing a motor that is no longer available (part 131511900) with a used later model (part 134156500). The new one is identical except for the wiring harness. Existing has switch with Connector and second harness whereas the replacement motor only has the switch. My plan is to remove the existing motor harness and switch and splice on to replacement motor but I am confused by the wiring. Motor has 4 wires from the windings. 2 light gauge that I assume are to the starter winding and 2 that heaver that go to the main coil? Is there a way to know which end of the 2 Pairs of the winding go to the harness wires? I tried one option and the motor turned but there was a spark from the circuit board and I aborted.

    Hi,

    I have not tried to put an incorrect motor in to replace an NLA one.
    Would need wire diagram from old and for new so we can compare the two....what is the extra plug for on the old motor?

    Top part of the diagram is missing, also the pic is a bit small...I tried to enlarge a bit but it just got blurry.

    I picked a model# that uses the newer motor...

    M4 and M5 run the motor, goes through the safety/thermal switch and both windings.
    M1 and M2 are for the heat switch, this operates nothing inside the motor but this switch closes when the motor is up and running to complete the circuit for the heat.

    I could not find a good diagram for your old model...see it here.

    Not sure if this can help, but I had the same reversing motor that failed to start intermittently. I tested the start switch on the motor and found that it sometimes failed to connect the start winding. I opened the switch assembly and will install a little shim on the leaf switch actuator which is a little worn out. That should solve the problem.

    This happened to me too a few years back. The switch was just failing to connect. You're way better than I am, I just had it replaced.
