The TQ3 cools its control with a fan that draws air from below. If the fan cannot turn or the unit sits too low to breathe, the board overheats and the screen shows Control Board Overtemp. The manual's checks are a clear fan, voltage to the fan, the unit standing on its legs and a clear filter area. Hatco commercial appliance display · also shown as Control Board Overtemp What to do when Control Board Overtemp shows on the commercial appliance ### Kind of code Temperature and alarms The controller has seen a temperature outside the band it was set for and is saying so: a box above its alarm point, a fryer vat or an oven cavity that tripped its high-limit, or a dish machine rinse that never came up to heat. Often the cause sits outside the unit, such as a door left open during a delivery, a coil packed with grease, a kitchen far hotter than the maker allows or a booster fed cold water. Checking the door, the coil and the air around the unit is fair; move the product if a cold box stays above 41°F, and book the visit. ### Usually leads to Reach-in and prep table repair Reach-ins, pass-throughs, prep tables and blast chillers: gaskets, hinges, fans, thermostats, condensers and compressors. ### Shows up as Commercial Appliance Error Code on a Combi, Fryer, Dish Machine or Laundry Display A commercial appliance error code appears as letters or numbers on a combi, fryer, reach-in controller, dish machine or laundry machine display, or as a flashing light or an alarm tone. ### Make Hatco Hatco equipment is often checked in the gap between breakfast and lunch, when the station it serves can do without it for a short while. ### Source Hatco Toast-Qwik TQ3-400, TQ3-500, TQ3-900 and TQ3-2000 conveyor toaster installation and operating manual Toast-Qwik TQ3-400, TQ3-500, TQ3-900 and TQ3-2000 conveyor toasters with the touchscreen control. ## Before you book, in this order.

Switch off and unplug the toaster and let it cool. If it comes back, it needs a visit. ### Why does my Hatco toaster overheat its board when it sits on the counter? The TQ3 needs its legs to draw cooling air from underneath. Without them the intake is blocked. ### Can crumbs cause Control Board Overtemp on a Hatco TQ3? Yes, crumbs and grease around the intake restrict airflow. Keep the area under and around the filter clean. ### Is Control Board Overtemp dangerous on a Hatco toaster? The message protects the board. Unplug the toaster, open up the airflow, and arrange service for a repeat. --- **[Read on the site: Hatco Control Board Overtemp: the Toast-Qwik electronics are too hot](https://commercialappliancerepair.center/error-codes/hatco-control-board-overtemp/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
