Home ovens built from December 2023 use a touchscreen controller. When the floor thermocouple is not plugged into the control box, or the thermocouple is damaged, the screen shows System Error! with a probe message. Wood Stone pizza oven display · also shown as System Error What to do when System Error! shows on the pizza oven ### Kind of code Temperature and sensors A probe is handing the controller a reading it cannot believe, or none at all: a deck or tunnel sensor coated in baked-on flour and grease, its lead chafed or scorched where it passes the heat, or a connector loosened by years of doors slamming. The oven then runs hot, stalls short of its setting or shuts the heat off to protect itself. Letting the oven cool and restarting it is reasonable; a sensor that still reads wrong sits behind a panel, and that is a visit. ### Usually leads to Pizza oven thermostat and control repair Thermostats calibrated or replaced, probes, timers, boards and displays repaired, so the pizza oven holds the temperature the cooks set and shows the right number. ### 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 Wood Stone Where a Wood Stone oven faces the dining room, the tech plans the visit around guests who can watch the hearth from their tables. ### Source Wood Stone Mountain Home and Traditional Home installation and operation manual (M0365) Mountain Home and Traditional Home gas and gas/wood ovens built in December 2023 and later, with the touchscreen controller. ## Before you book, in this order.

Turn the oven off at the screen and at the breaker. If it comes back, it needs a visit. ### What does System Error! mean on my Wood Stone home oven? The touchscreen controller has lost its hearth thermocouple, either because it is unplugged at the control box or because the sensor is damaged. ### Can I bake while my Wood Stone home oven shows System Error!? Without the floor reading the controller cannot manage the hearth, so leave it off until the sensor is reconnected or replaced. ### Which Wood Stone home ovens show System Error!? Mountain Home and Traditional Home ovens built from December 2023, which use the touchscreen controller. --- **[Read on the site: Wood Stone System Error!: the home oven's hearth probe is missing](https://pizzaovenrepair.center/error-codes/wood-stone-system-error/)** **[Book a visit with PizzaOvenRepair.center](https://pizzaovenrepair.center/schedule/)**
