On Wood Stone touchpad controllers the infrared burner under the hearth gets a fixed window to light once it is called for, 90 seconds on the IR burner. If its pilot does not prove a flame inside that window, the gas valve times out and the display flashes chec while the Hearth Heat light blinks. The dome flame may keep running, so the oven still looks alive. Wood Stone pizza oven display · also shown as check, CHEC What to do when chec shows on the pizza oven ### Kind of code Ignition and flame The oven tried to light its burner and never proved a flame, or proved one and then lost it. The usual reasons are ordinary: a gas shutoff not fully open or a tank running dry, an igniter cracked or crusted with flour dust, a flame sensor or thermocouple that no longer reads the heat, or a draft that pulls the pilot away from it. Checking the shutoff and the tank and running the restart the manual names are fair first steps; if you smell gas, get outside first, and the valve, the sensor and every fitting stay with a technician. ### Usually leads to Pizza oven burner and igniter repair Pizza oven burners cleared or replaced and igniters fitted and gapped, so the flame lights first time and burns blue and steady under the stone. ### 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 Fire Deck service manual (M0011.11) Type 2 touchpad controllers (since mid-2000) on Mountain Series, Traditional Series and Fire Deck ovens with an underfloor IR burner.

Switch the oven off at the controller, wait five minutes, then switch it on again; that is the reset Wood Stone gives for this message. If it comes back, it needs a visit. ### Why does my Wood Stone oven show chec while the dome flame is burning? The dome burner and the underfloor burner light separately. chec reports only the underfloor infrared burner, which failed to prove a flame in its time window while the dome flame kept going. ### How do I clear chec on a Wood Stone controller? Turn the oven off and back on. If the floor burner lights on the next call, carry on; if chec comes back, the underfloor ignition needs a technician. ### Can I light the Wood Stone underfloor burner by hand after a chec? No. Wood Stone warns never to light that burner manually; it lights only through its own hot-surface igniter and valve, so a repeat chec means a visit. --- **[Read on the site: Wood Stone chec: the underfloor burner did not light in time](https://pizzaovenrepair.center/error-codes/wood-stone-chec/)** **[Book a visit with PizzaOvenRepair.center](https://pizzaovenrepair.center/schedule/)**
