Press Dismiss and move orders to the belt that is still running. If it comes back, it needs a visit. ### Why does my Middleby Marshall X55 still bake with BELT COMM LOST showing? The manual says the oven continues on a single belt when one drive board loses power. You can keep serving on the working lane until the repair. ### What trips the belt breaker on a Middleby Marshall? A jam that makes the motor work too hard is the usual reason, which is why the manual asks you to check the belt before resetting. ### Is FRONT BELT COMM LOST a network problem? No. It is the oven's control losing contact with the belt's drive board inside the oven, not anything to do with the internet. --- **[Read on the site: Middleby Marshall FRONT BELT COMM LOST: a conveyor drive board has lost power](https://pizzaovenrepair.center/error-codes/middleby-marshall-front-belt-comm-lost/)** **[Book a visit with PizzaOvenRepair.center](https://pizzaovenrepair.center/schedule/)**
