Check for continuity at relay coil, and

 

 

visually check for pull in of contacts.

 

20 Minute Time Delay

Check for 120 VAC at terminals #1 to

 

 

neutral on 20 minute Time Delay Relay.

 

 

If no voltage is present, trace wiring

 

 

back to power source. If voltage is

 

 

present at terminal #1, check for 120

 

 

VAC at terminal #2 to neutral. If no voltage is

 

 

present, and Main Fan Switch is closed, replace

 

 

Time Delay.

 

Main Fan Relay

Check for 120 VAC to coil of the Relay.

 

 

If no voltage is present, trace wiring

 

 

back to 20 minute Time Delay Relay. If

 

 

voltage is present, check to insure

 

 

contacts are closing.

 

Main Fan Motor

Check for opens, shorts, or grounds.

 

 

WITH POWER OFF: Turn fan blade to

 

 

check for locked rotor.

 

Capacitor

Check for opens, shorts, or grounds.

No main fan cool down

20 Minute Time Delay

Check for 120 VAC at terminal #2 to

 

 

neutral while oven is “on”. Turn off the

 

 

main fan switch, 120 VAC should

 

 

continue to be present for 20 minutes.

 

 

If voltage is not present for
