*If oven light is not working, make the following checks:
• Check oven light bulb.
• Light is to come on when the door is opened–check
voltage across light socket. Terminals should read 120
VAC. If 0 volts, check jamb switch and wiring.
• Light is to come on when control light pad is pressed.
K11 or K12 should click. Check voltage from N to J6-3
(upper) or N to J6-1 (lower). Should read 120 VAC. If 0
volts, check oven light keypad using Ohmeter Test. If
keypad is good, replace the control.
**If convection fan not running, make the following
checks:
• Check the voltage from terminal CN01-3 to N on
control–it should read 120 V in Conv. Bake or Roast
mode.
• If voltage OK, check convection fan motor. It should read
approx. 15-20 Ω at room temp. Check to make sure the
fan shaft is not rubbing on the oven liner.
• Check Door Switch.
