What FRONT BELT JAMMED
actually means.
Split-belt Middleby Marshall conveyors drive the front and rear belts separately. When the front one is overloaded or something stops it, the control shuts that belt down and shows this message. The X-Series words it as FRONT BELT STALLED.

What to do when FRONT BELT JAMMED 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.

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 JAMMED on its pizza ovens. Follow it to the end: the last card says whether this is a visit.
Turn the oven off and let it cool before reaching toward the belt.
Look along the front belt at both ends and inside the opening for a dropped pan, a screen or dough wrapped around a shaft, and remove it.
Restart the oven; on an X-Series press Dismiss and follow the prompts.
If the belt stays stopped with nothing in the way, book a visit: the belt breaker sits behind the control door and the drive may need attention.

What not to do
The message does not mean the belt speed setting has changed; a belt that runs at the wrong speed is a settings check. It also differs from FRONT BELT COMM LOST, where the drive board has lost power rather than the belt being blocked.
