An hour of open door is long enough to warm the cabinet. Turbo Air commercial appliance display · also shown as Ed What to do when ED 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 Turbo Air Turbo Air cabinets in a busy kitchen tend to get a visit between shifts, with the manager present to sign off the log. ### Source Turbo Air PCB settings service sheet (control menu and error codes), turboairinc.com resource center Read from the error code item (ER) of the control menu, opened by holding both temperature buttons until SL shows, as laid out on Turbo Air's PCB settings sheet. ## Before you book, in this order.

Close the door firmly and check nothing is holding it open. If it comes back, it needs a visit. ### Why does my Turbo Air record ED? The door switch saw the door open for an hour. Check for a propped door or a gasket that does not seal. ### Can a Turbo Air door switch be set wrong? Turbo Air's settings sheets include a door switch type setting. A wrong setting or a worn switch can both cause false door readings. ### Does ED mean my Turbo Air food is unsafe? Not by itself. Probe the food and follow your health code if it has been above 41°F. --- **[Read on the site: Turbo Air ED: a door has been open for an hour](https://commercialappliancerepair.center/error-codes/turbo-air-ed/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
