Service Tips Pre heat in bake will take about 17 minutes This will allow for a more stable heat in 1st bake session 208 V application will affect only the clean cycle The bake and broil elements cycle together, if oven is not set in 208V mode, the proper heat will not be achieved and the clean may not be as effective

Service Tips Setting the oven for 208V (self clean) Turn off oven Open oven door Press off key (upper off key in double ovens) While holding off key, press Clean key When display reads 240, release keys Press clean key to change display to 208 Press off key, oven is set to 208V

Service Tips Halogen light transformer On single ovens, the relay switches the voltage to the primary of the transformer On double ovens, the relay switches the voltage to the secondary of the transformer

Service Tips Keep Alive Time Prevents control from loosing program during a power interruption or power glitch To reset the control the power must be off for a period of three minutes or longer If probe leads are wired in reverse the board will sense that the probe is installed and the probe indicator light will display..no other modes will operate

Service Tips When replacing the sensor Cut old sensor leads close to the sensor Make the splice with the high temp splices provided Use wire or thin screwdriver to push splices all the way through the insulation..until you hear it hit the back panel This will assure that the splices are not in the heat zone
