SYMPTOM POSSIBLE CAUSE EVALUATION Oven fan will not run Incoming power supply Check circuit breakers, reset if required. Check power plug to be sure it is firmly in receptacle. Measure incoming power, call power co. if needed. Check, replace if necessary. Check, replace if necessary. Check for voltage on both sides of switch.
Main fan Centrifugal switch of main fan motor 8 If not operating, refer to “Oven fan will not run”. Check for 120VAC at wire #5 (input to centrifugal switch, located at 6-pin connector in raceway near the main fan motor) to neutral. If no voltage is present, trace wiring back to the main power switch. If voltage is present, check for 120VAC at wire #22 (output of centrifugal switch) to neutral. If no voltage is present at #22, and the motor is running, replace the main fan motor.
Flame will not stay lit Hot surface igniter Power supply Ignition control valves, the valve should open. Check for gas pressure at the manifold tap located just before the burner. If there is no pressure, check the incoming gas supply to be sure all manual valves are open and flexible gas hose is properly connected. If gas is present, and the gas control valve is energized, but there is no gas pressure at the burner manifold, replace the gas control valves.
Intermittent heating Conveyor will not run 10 voltage output at the oven control, check the readout on the control. If the control reads “PROBE FAIL”, this indicates that the thermocouple has failed or become disconnected from the oven control. Thermocouple Check to be sure that the thermocouple is securely connected to the oven control.
Conveyor motor Capacitor, conveyor motor Switch, conveyor reversing Oven control Conveyor motor runs, but there is no speed display NOTE: Display will indicate “Belt Jam” Oven control Conveyor motor Oven control Impinger II – Advantage Digital Service Manual - Domestic wiring back to the oven power relay. If voltage is present, check for 24 VAC at the transformer secondary. If there is primary voltage but no secondary voltage, replace control transformer.

If thermostat will not hold for maximum oven temperature, and oven is not exceeding temperature setting, check for proper location of capillary bulb in its spring holder. If the capillary checks okay, replace the hi-limit thermostat. Check for 120VAC supply to the primary of the control transformer.
Oven heats with switch off Intermittent heating Conveyor will not run 14 activate, replace the mercury contactor. Also check each contactor for high voltage input and output. Heating element(s) Check the Amp draw on each power leg for proper load. Check the specification plate for rating information. If the amp draw is high or low, check the individual elements for opens, shorts and proper resistance.
Switch, conveyor reversing Oven control Conveyor motor runs, but there is no speed display NOTE: Display will indicate “Belt Jam” Oven control Conveyor motor Oven control Impinger II – Advantage Digital Service Manual - Domestic discharge before testing. Check continuity between switch terminals. Replace switch as needed. If there is supply voltage to the motor, and the motor, capacitor, and reversing switch check good, replace the oven control.
