– 71 –Mini Manual # 31–17121–1 (available on website).Dead Unit If Control does not show any display, after verifying the circuit breaker is ON, checkfor 120 VAC at the black wire on the BROIL relay to the white wire on J102, withwires still connected to board. If 120 VAC is present, Control needs to be replaced. Ifless than 90 VAC, check voltage from the white wire on J102 to the chassis ground;if 120 VAC, neutral limit switch is open, or house supply voltage is at fault.$//7(676%(/2:$5(5(6,67$1&(&+(&.6³',6&211(&729(1)52032:(5No Bake If the Bake element is not energizing, check the resistance on the yellow wire of thebake relay to the orangeZLUHRQWKH'/%UHOD\$SSUR[LPDWHO\űNo Broil If the Broil element is not energizing, check the resistance on the purple wire of thebroil relay to the orangeZLUHRQWKH'/%UHOD\$SSUR[LPDWHO\űNo Convection If the Convection element is not energizing, check the resistance on the blue wire ofJ803 to the orangeZLUHRQWKH'/%UHOD\$SSUR[LPDWHO\űNo Bake, Broil orConvectionIf all elements are not energizing, the L2 High Limit Switch is open.All 120 volt componentsNo Cooling FanMotor HighIf the Cooling Fan High is not energizing, check the resistance on the black/whitewire on J801-3 to the whiteZLUHRQ-$SSUR[LPDWHO\űNo Cooling FanMotor LowIf the Cooling Fan Low is not energizing, check the resistance on the red/white wireon J801-2 to the whiteZLUHRQ-$SSUR[LPDWHO\űNo Cavity Lamps If the Cavity Lamps are not energizing, check the resistance on the black wire onJ801-1 to the whiteZLUHRQ-$SSUR[LPDWHO\űNo Convection Fan If the Convection Fan Motor is not energizing in the clockwise direction, check theresistance on the blue wire on J801-5 to the white wire on J102.
