The code resets itself once the temperature returns to normal, and the alarm icon stays lit. Hoshizaki commercial appliance display · also shown as LO What to do when Lo 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 Hoshizaki On a Hoshizaki cold cabinet in a restaurant, the tech first finds out when the last good temperature was written on the log. ### Source Hoshizaki Steelheart Series upright A-Series service manual 73237 (archived copy of the Hoshizaki America PDF) Steelheart upright A-Series and Commercial Series upright S-Series: 26°F for coolers, -23°F for freezing cabinets.

Check the setpoint on the display and correct it if someone has lowered it. If it comes back, it needs a visit. ### What makes a Hoshizaki cooler run too cold? A setpoint lowered on the display is the most common cause. When the setpoint is right, a sensor reading warmer than the air or a control holding the compressor on comes next, and both need a technician. ### How far should I change a Hoshizaki setpoint at once? Hoshizaki asks for no more than 2°F per change and at least eight hours for the cabinet to settle before the next one. Big jumps are how a cooler ends up in Lo. ### Will Lo damage food in my Hoshizaki reach-in? It can freeze produce, eggs and dairy, especially near the air outlet. Check those items first and move them to a shelf farther from the fan. --- **[Read on the site: Hoshizaki Lo: the cabinet has held too cold for two hours](https://commercialappliancerepair.center/error-codes/hoshizaki-lo/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
