The circuit board mounted on the control panel has three status 
LED indicators to help troubleshoot if the oven is not heating: 

 

If LED 1 is not lit, check 2F and 3F (control fuses), or power 
switch. 

 

If LED 1 and LED 3 are lit but not LED 2, check high limit 
(and optional door switch, if installed). 

 

If all three LEDs are lit, check 1F and 4F (heater fuses), SSR, 
heater, and heater relays.
