The Cross Temp control blinks uHi when the line voltage rises above its set limit. The alarm is always active. High voltage heats motors and can harm the control, so it is worth finding quickly. Beverage-Air commercial appliance display What to do when uHi shows on the commercial appliance ### Kind of code Controls and power The controller itself is reporting trouble, or the supply behind it is: a display with dead segments, a keypad that stopped responding after steam or degreaser got behind it, relays that stick, stored recipes or cycles that vanished overnight, a blown control fuse, or one leg of a three-phase feed missing so half the heat or the pump is gone. A full power cycle at the breaker, done as the manual describes, clears a passing glitch; a code that returns, a scorched smell or any sign of moisture behind the panel means the breaker stays off, and that is a visit. ### Usually leads to Commercial controls and board repair Controllers, touch panels, relays, contactors and interlocks tested, and replaced only when the evidence says so. ### 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 Beverage-Air When a Beverage-Air cabinet drifts warm mid-shift, the first minutes of the visit go to where the food went and what the temperature log recorded. ### Source Beverage-Air Cross Temp (CT) freezer/refrigerator user manual, 809-154A (rev. 02/26) Listed in the electronic controller alarms table of Beverage-Air's Cross Temp (CT) manual (rev. 02/26). ## Before you book, in this order. Each step comes from Beverage-Air's own guidance for uHi on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Note when uHi appears and what else was running. 02 Have an electrician measure the outlet voltage. 03 Book a visit if uHi remains once the supply reads normal. ### Still there? It usually turns into [commercial controls and board repair](https://commercialappliancerepair.center/services/commercial-controls-and-board-repair/). Book with the code and the model number. ### What not to do uHi is not a temperature alarm and not a failed control. Its opposite, the low voltage alarm, is uLi. ## What you may notice with it. The commercial appliance problem uHi tends to arrive with. Answer these at the commercial appliance before anyone is booked.

Note when uHi appears and what else was running. If it comes back, it needs a visit. ### What causes uHi on a Beverage-Air? A problem in the building supply, such as a loose neutral. The outlet is measured before the unit is blamed. ### Is uHi on a Beverage-Air dangerous? It can damage electrical parts over time. If you smell hot wiring, switch off at the breaker from a dry spot. ### Can I turn off uHi on my Beverage-Air? The Cross Temp manual lists it as always active, so fix the supply rather than the alarm. --- **[Read on the site: Beverage-Air uHi: the line voltage is too high](https://commercialappliancerepair.center/error-codes/beverage-air-uhi/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
