Main fan If not operating, refer to “Oven fan will not run”. Centrifugal switch of main fan Check for 120VAC at wire #5 (input to centrifugal motor 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. Hi

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. Flame will not stay lit Hot surface igniter Six seconds after the gas valve opens, ignition must occur

voltage output at the oven control, check the read- out 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. If the thermocouple is connected to the oven control, and the control indicates “PROBE FAIL”, disconnect the thermocouple from the oven control and measure the resistance of the thermocouple. T

Conveyor motor Check for 120 VAC supply to the conveyor motor at wire #14 to neutral. If no voltage is present, trace wiring back to the primary of the control transformer. If voltage is present and the motor will not run, check the motor windings for opens or shorts. WITH POWER OFF: Check the moto
