The high limit is a separate safety switch with its own manual reset. When the cavity passes 671°F, it sends a 24-volt signal to the relay board and the control shows High Temp Error. Blodgett's sheet sends the technician to three places: the heating contactor, the limit itself tripping too early, and the limit signal wire shorting. Blodgett commercial appliance display · also shown as High Temp Error What to do when High Temp Error 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 Blodgett A Blodgett visit tends to land early in the morning, before the first sheet pans go in and while the cavity is still cold. ### Source Blodgett combi and HydroVection control error codes service sheet Listed on Blodgett's error codes service sheet for its combi and HydroVection electronic controls; the sheet does not name individual models. ## Before you book, in this order. Each step comes from Blodgett's own guidance for High Temp Error on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 End the cook and allow the oven to cool down, door shut. 02 Do not try to reach the high limit reset behind panels yourself. 03 Arrange a service call; the contactor, the limit and its signal wire all have to be tested before the oven heats again. ### Still there? It usually turns into [reach-in and prep table repair](https://commercialappliancerepair.center/services/reach-in-and-prep-table-repair/). Book with the code and the model number. ### What not to do High Temp Error is not the same as Cavity High Temp Error, which comes from the cavity probe; this one comes from the independent limit switch. It can also appear without real overheating when the limit wire shorts, which is why testing matters. ## What you may notice with it.

End the cook and allow the oven to cool down, door shut. If it comes back, it needs a visit. ### Can staff reach the manual reset on a Blodgett combi high limit? No. It sits behind the control or service panels, which is why Blodgett's sheet is aimed at technicians. Owners should not open those panels. ### Can High Temp Error on a Blodgett happen without real overheating? Yes. A limit that trips early or a shorted signal wire can bring it, and a meter test is the only way to separate them. ### What temperature trips the Blodgett high limit? Blodgett gives 671°F in the oven cavity. --- **[Read on the site: Blodgett High Temp Error: the manual-reset high limit has signaled](https://commercialappliancerepair.center/error-codes/blodgett-high-temp-error/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
