What FRONT BELT COMM LOST
actually means.
On the X-Series each belt has a motor drive board fed through its own circuit breaker. If that breaker trips, the control loses contact with the board and shows FRONT or BACK BELT COMM LOST. The oven continues with the one working belt.

What to do when FRONT BELT COMM LOST shows on the pizza ovenKind of codeConveyor belt and drive
The belt stopped, slowed or lost track of its speed. Sometimes a pan, a lid or a clump of burnt cheese has jammed the belt against the frame; more often the drive motor is worn, a coupling or a chain has slipped, or the speed sensor no longer reports what the belt is doing, so the bake time on the display stops matching the pies. Clearing the belt path once the oven is off and cold is a fair first step; a motor that hums without turning or a belt that has stretched out of true is a visit.

Conveyor oven belts, sprockets, drive motors, gearboxes and speed controls repaired, so pizzas ride through the tunnel at the set speed and never stall inside.
Shows up asPizza Oven Error Code on a Deck, Conveyor or Rapid-Cook Display
A pizza oven error code shows as letters or numbers on the display of a conveyor, deck or rapid-cook oven, a flashing light on its panel, or a message about ignition, heat, belt or airflow.

A Middleby Marshall conveyor call is about the line: how many pies came out right before the belt slowed, stalled or the crust went pale.

Before you book,
in this order.
Each step comes from Middleby Marshall's own guidance for FRONT BELT COMM LOST on its pizza ovens. Follow it to the end: the last card says whether this is a visit.
Press Dismiss and move orders to the belt that is still running.
With the oven off and cool, check the affected belt for anything that could have jammed it and tripped the breaker.
Resetting that breaker means working at the oven's control compartment, so book a visit to reset it and find out why it tripped.

What not to do
COMM LOST on a belt is not the display losing contact with the main board, which the X-Series calls I/O COMM LOST. It is also not a stalled belt, where the drive has power but the belt is blocked.

A booking with a code goes further when it has the code copied as shown, the model and serial from the rating plate, and a note on whether the oven still lights, heats or moves its belt. With those three, the office can match the likely part to your oven the same day.
