No high speed (final) spin
Hi Jake,
Thanks for your response.
Let me explain what is going on with my washer. The washer is working fine during wash and rinse. When it comes to the final spin the washer tub is moving back and forth like it is doing wash and rinse. The drain pump is running.
For your info this is the first time I am working on a washer but I have been working on other appliances before.
On the Technical Sheet there is an explanation on Motor Movement as follow:
1. Check the power:
Advance the timer knob to the drain increment. If the drain pump does not run, check household safety circuit. If the drain pump runs go to step 2.
Done, drain pump is running.
2. Check for Motor Movement:
Turn the water off to the washer. Remove electrical power from the washer and remove the back panel. Remove the motor drive belt. Reconnect electrical power and set the timer to the start of the Regular wash cycle and pull the knob out. If motor does not rotate, check for a poor connection in the timer line switch or door lock switch. If good, and motor does not run go to step 3.
Done, motor is running when the timer is set to the Heavy Wash position of the Regular was cycle only.
3. Measure Voltages:
Remove the six pin plug from the speed control unit. Measure the voltage between pins 5 and 6 of the harness. If the meter reads 0 check the connection in the timer line switch or door lock. If the meter reads 120 Vac go to step 4.
Done, meter reads 120 Vac.
4. Set the timer to the Heavy Wash position of the Regular wash cycle. Remove the ten pin plug from the speed control unit. Measure the voltage between pins 1, 2, 6 and 10 of the ten pin plug to pin 5 of the 6 pin plug on the harness. The voltage at pins 2, 6 and 10 should read 120 Vac and 0 Vac at pin 1.
Done, but the result is different. Pins 1 and 10 showed 120 Vac but pins 2 and 6 showed 0 Vac. There is no cable at pin 2 of the ten pin plug on the harness.
If not, check timer contacts 1C to 1B, 5C to 5B, and 7C to 7B for closed contacts, and 3C to 3B for open contacts. If the voltage readins are correct, go to step 5.
Not done, because of the different result on previous step.
Why is the ten pin plug harness different than the technical spec?
5 Measure Resistances:
Check the fuse on the speed control board. If the fuse is open, replace the speed control board. If good, go to step 6.
Not done, but I assume it is good because the motor is running.
6. Remove the 6 pin plug from the speed control unit. Measure the resistance between pins 1 and 2, 2 and 3, and 3 and 1 of the speed control unit. If the meter reads other than 3 Meg ohms + 10%, replace the speed control board.
7. Remove electrical power from the washer. With an ohmmeter check the resistance between pins 1 and 2, 2 and 3, and 3 and 1 of the six pin plug on the harness. If the meter reads other than 2.6 ohms + 7 %, replace the motor.
Your comments or suggestions will be appreciated.
Thanks,
