The rear belt on a split conveyor usually runs the second bake time, often for a different product. If it is overloaded or caught, the control stops it and names it on the screen. X-Series ovens call it BACK BELT STALLED, and the front lane can keep working. Middleby Marshall pizza oven display · also shown as Rear Belt jammed, BACK BELT STALLED What to do when REAR BELT JAMMED shows on the pizza oven ### Kind of code Conveyor 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. ### Usually leads to Conveyor oven belt and motor repair 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 as Pizza 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. ### Make Middleby Marshall 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. ### Source Middleby Marshall PS640 series gas oven owner's operating and installation manual (60251 Rev J) PS638 and PS640 gas touch screen ovens print REAR BELT JAMMED; X70G, X55G and X55GWB print BACK BELT STALLED. ## Before you book, in this order.

Switch the oven off and wait for it to cool; the rear belt sits deeper in the opening and is harder to reach safely. If it comes back, it needs a visit. ### Can I keep using the front belt while the rear shows jammed? The front belt has its own drive, so it can keep running. Clear the rear lane at the next safe moment with the oven off and cool. ### Why does the rear belt on my Middleby Marshall jam more often? It often carries the heavier or longer bake, and items slide toward it from the loading shelf. Overload is the cause the manual lists first. ### What is BACK BELT STALLED on a Middleby Marshall X-Series? It is the X-Series wording for the rear belt being stopped by the control after an overload or jam. --- **[Read on the site: Middleby Marshall REAR BELT JAMMED: the back conveyor lane has stopped](https://pizzaovenrepair.center/error-codes/middleby-marshall-rear-belt-jammed/)** **[Book a visit with PizzaOvenRepair.center](https://pizzaovenrepair.center/schedule/)**
