Delfield sets the alarm to sound and flash 90 minutes after the cabinet reaches its alarm point, or after a power interruption if the temperature is outside the limits. On R290 reach-ins the high point is 50°F for a cooler and 20°F for a low-temperature cabinet. By the time Hi shows, food near the door has likely been warm for a while. Delfield commercial appliance display · also shown as HI What to do when Hi 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 Delfield For a Delfield station that runs warm by late lunch, we time the visit to a slow hour so the pans can come out and the rail can be tested empty. ### Source Delfield 6000XL and 6100XL Series reach-ins, installation, operation and maintenance manual, part 9294254 (archived copy of the delfield.com PDF) Listed in the operation and indication table of Delfield's R290 reach-in manual (6000XL/6100XL) and prep table manual (4400/4500 Series).

Probe the food straight away and log the reading and the time. If it comes back, it needs a visit. ### Why did my Delfield stop beeping but still show Hi? Delfield's alarm sounds in short bursts for 15 cycles and then goes silent. The code stays on the display until the temperature comes back into range. ### How warm is a Delfield cabinet when Hi appears? On the R290 reach-ins, a cooler alarms at 50°F and a low-temperature cabinet at 20°F, and only after 90 minutes above that point. ### Can a Delfield show Hi after a power cut? Yes. The manual says the alarm can come on after a power interruption if the cabinet is still outside its limits when power returns. --- **[Read on the site: Delfield Hi: the cabinet passed its warm alarm point 90 minutes ago](https://commercialappliancerepair.center/error-codes/delfield-hi/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
