Broken wires at one of the out off balance switches or a bad switch itself.
A fairly common trouble maker has been a burnt diode on the main control board. See diode R11.
Troubleshooting: Washer Fills but Will Not Tumble
- Check to make sure the Drive Belt has not come off of the Motor and Pulley. Reposition the Drive Belt if needed.
- Check the wiring at the Machine Control.
- Check the wiring between the Machine Control (Connector P4) and Motor Control (Connector JP4) and between the Motor Control (6 phase wires and the 3-position connector) and Motor (6- and 3-position connectors).
- Perform the Drive System Diagnostic Test.
Troubleshooting: Washer Will Not Spin
- Set the Timer Knob into a Spin increment and start the washer. Check to make sure the Door Locked Light comes on, after a 30-60 second delay.
- If the Door Locked Light does not come on, check for 120 vac across the Door Lock Wax Motor.
- If 120 vac is present when the washer is running in a Spin increment but the Door Lock Wax Motor does not extend fully, replace the Door Lock Switch Assembly.
- If the Door Lock Wax Motor does extend, check for continuity across the Door Lock, Spin Enable Switch when the switch actuator button is pressed in. If there is no continuity across the Door Lock, Spin Enable Switch, replace the Door Lock Switch Assembly. If there is continuity across the Door Lock, Spin Enable Switch, check the wiring between the Switch and the Machine Control terminal P3-7. If there is continuity in this wire, replace the Machine Control.
- If 120 vac is not present when the washer is running in a Spin increment, check the wiring between the Machine Control and Door Lack Wax Motor (brown wire no. 14). If there is continuity between the Door Lock Wax Motor and Machine Control terminal P7-4, replace the Machine Control.
Drive System Diagnostics
Troubleshooting: Drive System Diagnostics Test
- Set the Timer knob into the Delay increments
- Press the Push to Start Switch to start the washer in Delay mode. Confirm that the Delay Light comes on.
- Check for 120 vac between the L and N terminals (black wire no. 27 and white wire no. 13) on the Motor Control.
-Check the wiring between the Machine Control and Motor Control.
- Unplug the washer power cord.
- Remove the 6-position Connector JP4 from the Motor Control.
- Plug the washer power cord into the wall socket.
- Press the Push to Start Switch and confirm that the Delay Light comes on. The Washer should tumble continuously at 50 rpm in this test condition.
- If the washer tumbles, the drive system is functioning properly.
-If the washer does not tumble, check for continuity through the fuse on the Motor Control.
- If the fuse is functioning , check the six power transistors on the Motor Control for visible damage. Replace the Motor Control if any damage is evident.
- If there is no visible damage on the Motor Control, perform the Drive System Phase Loss Test.
- Unplug the washer power cord and replace Motor Control Connector JP4 when finished.
