- Page 7 Testing Main PCB power output to Heating & Motor circuit. With motor running in the heating mode, read AC voltage across RY6 and RY1. Any voltage reading means Main PCB is defective. See page 4 for Main PCB layout for testing. Testing Motor circuit.
- Page 8 Testing Electric Heater circuit. Disconnect Blue wire from RY6, turn power on, start dryer read voltage between RY6 Blue wire and CN6 Green wire. Reading of 120VAC means a proper operating heater circuit. 0VAC means open in circuit. To test thermostats use ohm meter on lowest scale, any resistance replace component See page 4 for Main PCB layout for testing.
