RY6 

CN6 

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.
