Whirlpool dryer motor ready for wiring.
- Disconnect the appliance from the power supply and remove the back cover with a screwdriver.
- Unscrew or cut the wires from the old motor and make a note of the color and corresponding number of each wire. Failure to do this will result in frustration and probable calls to a repairman.
- Remove the old motor by unscrewing the unit from the mounting brackets. Install the new motor on the mounting brackets and align in the same position as the old motor.
- Reattach wires as follows: Attach the red wire from the old motor's terminal 1 to terminal 1 on the new motor. Take the red wire that was on the old motor's terminal 2 and connect to terminal 2 on the new motor. Attach the purple wire from the old terminal 3 to terminal 3 on your new motor (note: some replacement wires are white for terminal 3). Connect the blue wire on terminal 4 to the dryer's thermal overload switch, which is a circuit breaker. Connect the white wire from terminal 5 to terminal 5 on the new motor. Attach the black wire that was on terminal 6 to the new motor's terminal 6.
- Slip the drive belt over the pulley on the motor and check for proper tension.
- Replace the dryer cover and reconnect the appliance to the power supply.
