*If the oven light is not working, make the following
checks:
• Check the oven light bulb to verify it works.
• The light comes on when the door is opened. Check
for 120VAC from OL terminal to L1. If 120 VAC is not
present, press the oven door switch in and out several
times, leaving the oven door open. Recheck for 120 VAC
from OL terminal to L1 with the oven door open. If
120 VAC is not present, replace the oven door switch.
• Close the oven door. Check for 120 VAC from OL
terminal to L1. If 120 VAC is present but the light does
not turn on, the light bulb is bad or there is a loose
connection in the wire harness. If 0 VAC, press Oven
Light key on key panel and retry. If still 0 VAC, check
the key panel. If the key panel is OK, replace the control. (If you hear a relay click when the Oven Light key
on the control panel is pressed, the key panel is working.)
**If the convection fan not running, make the following checks:
• Check the voltage from terminal CW and CCW to N on the control―it should always read 120 VAC in Conv.
Bake or Convection Roast modes.
• If the voltage OK, check the convection fan motor. It should read approx. 15–20Ω at room temperature.
Check to make sure the fan shaft is not rubbing on the liner.
• Check the door switch.
• Check the capacitor.
