Trouble Shooting Dryer
Electronic Control Diagnostic Lights
The electronic control has 3 diagnostic lights to aid in service of the dryer. The Dryer has indicator lights
for the motor circuit, door switch circuit, and the heat circuit. When the electronic control is carefully
unlocked and moved forward these lights are visible on the circuit board. They are each labeled as to
function indicated.
1. When dryer door is closed, the appropriate door light on the computer should be illuminated
indicating that the door is closed.
2. When dryer is running, the appropriate motor light on the computer should be illuminated
indicating that the computer is calling for the motor to operate.
3. When dryer is calling for heat, the appropriate heat light on the computer should be illuminated
indicating that the computer is calling for heat.
An example of their function would be troubleshooting the dryer pocket that did not heat.
1. Start the machine and insure that it did not heat.
2. Check the upper heat light and see if it is lit.
3. If the heat light is on, this would indicate that the computer was calling for heat and that it was
not at fault. You would then go on to check the rest of the heat circuit.
