What does Lincoln BELT JAM mean?

On Lincoln Impinger II Advantage Digital ovens with push-button controls, the conveyor uses a Hall-effect sensor and magnet to prove the conveyor motor is turning. When the control sees no motion signal, it shows BELT JAM on the display.

What does Lincoln PROBE FAIL mean?

On Lincoln Impinger II Advantage Digital ovens, the oven control reads cavity temperature from a thermocouple. When the control cannot read a valid signal, it displays PROBE FAIL, indicating the thermocouple has failed or become disconnected.
