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 Star Star equipment is usually checked in the slow window after breakfast, while the cooking surface cools. ### Source Star RTW14EA / RTW19EA rolling tortilla warmer owner's manual (star-mfg.com) Star RTW14EA and RTW19EA rolling tortilla warmers with the digital control. ## Before you book, in this order.

If the unit has just been switched on, let the preheat run; LOW TEMP is expected early in the warm-up. If it comes back, it needs a visit. ### Why does my Star tortilla warmer say LOW TEMP right after switching on? The drum starts cold. Until it passes 100°F a temperature check shows LOW TEMP rather than a number, which is normal during preheat. ### How do I see the real drum temperature on a Star RTW? Press SET/TEMP during preheat or TORT mode. Once the drum is over 100°F, the display shows the reading. ### What if the heater dot is on but LOW TEMP never clears? The control is calling for heat but the drum is not warming. That points to a heater or sensor, which needs a technician. --- **[Read on the site: Star LOW TEMP flashing on a tortilla warmer: the drum is under 100°F](https://commercialappliancerepair.center/error-codes/star-low-temp/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
