If thermostat will not hold, and control box temperature is not exceeding 140°F (60°C), replace thermostat. Power switch Check continuity between switch terminals. Replace switch as needed. Control transformer Check for 120 VAC supply to the primary of the control transformer. If no voltage is present, trace 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. 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 motor windings as follows: Grey to black - 38. approx. Grey to blue - 38. approx. Blue to black - 75. approx. If any of the above fails, replace conveyor motor. Capacitor, conveyor motor Check for shorts or grounds. Replace capacitor as Impinger II – Advantage Digital Express Service Manual - Domestic needed. WARNING: Capacitor has a stored charge, discharge before testing. Switch, conveyor reversing Check continuity between switch terminals. Replace switch as needed. Oven control If there is 120VAC supplied to the motor, and the motor, capacitor, and reversing switch check good, replace the oven control. Conveyor motor runs, but there is no speed display NOTE: Display will indicate “Belt Jam” Oven control Check for output voltage from oven control to hall effect sensor (sensor is located in conveyor motor). Measure voltage at the motor connector, red wire and yellow wire. Voltage should be approx. 10VDC. If no voltage is present, trace wiring back to oven control. If there is no voltage present at the oven control, replace the oven control. Conveyor motor If there is voltage supplied to the hall effect sensor, check for a frequency output from the hall effect sensor. Measure frequency across the yellow and white wires at the motor connector. Frequency reading should be approx. 25 – 100 Hz. If these readings are not achieved, replace conveyor motor. If the readings are achieved, proceed. Oven control If the hall effect sensor readings are correct, but there is no speed indicated on the display, replace the oven control.
