--- title: "Hatco Lo: the display cabinet is still below 70°F" description: "What Lo means on Hatco Lo: the display cabinet is still below 70°Fs, what to check before booking, and when it is not a failure at all." url: "https://commercialappliancerepair.center/error-codes/hatco-lo/" --- # Hatco Lo: the display cabinet is still below 70°F The cabinet temperature display on the FSCD shows the air temperature once it is measurable, and anything below 70°F appears as Lo. ## What Lo actually means. The cabinet temperature display on the FSCD shows the air temperature once it is measurable, and anything below 70°F appears as Lo. It is normal right after startup; the manual allows about 30 minutes to reach holding temperature before preheated food goes in. Hatco commercial appliance display · also shown as Lo What to do when Lo shows on the commercial appliance ### Kind of code Mode, not a failure Nothing on the unit has broken; the controller is reporting a state it chose or one somebody set. A defrost pauses cooling for a scheduled melt and shows a warmer air reading for a while, a combi asks for a delime or runs its clean cycle and locks the door until it ends, a dish machine or a laundry machine sits in energy save between busy periods, and a door-open reminder beeps after a long delivery. No part is needed: letting the cycle finish, or the key sequence in the manual, brings the unit back. ### Usually leads to No repair Give the cabinet 30 minutes after switching on before loading food. ### 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 Hatco Hatco equipment is often checked in the gap between breakfast and lunch, when the station it serves can do without it for a short while. ### Source Hatco Flav-R-Savor FSCD and FSCDH convected display cabinet installation and operating manual (Form FSCDM-1016) Flav-R-Savor FSCD non-humidified convected display cabinets. ## Before you book, in this order. Each step comes from Hatco's own guidance for Lo on its commercial appliances. Follow it to the end: the last card says whether this is a visit. 01 Give the cabinet 30 minutes after switching on before loading food. 02 Check the set temperature and make sure the doors are closed. 03 If Lo stays after 30 minutes with the power switch on, book a visit; the manual lists a tripped high-limit, a blower motor or a heater among the causes of no hot air. ### Cleared? The code is gone from the controller, the box pulls down to its set point and holds it, the vat or the cavity reaches temperature and recovers on schedule, the rinse hits its heat and the drum finishes its spin, all without a new part. If the same code comes back within a week, or during the next busy shift, mention it when you book. ### What not to do Lo is a reading, not an error code, and it is expected during warmup. LO H2O on humidified models is a separate prompt that asks for water. ## What you may notice with it. The commercial appliance problem Lo tends to arrive with. Answer these at the commercial appliance before anyone is booked.

Give the cabinet 30 minutes after switching on before loading food. ### How long should a Hatco display cabinet show Lo after startup? Only until the air passes 70°F, which should happen well within the 30 minutes Hatco allows for warmup. ### Can I load food while my Hatco cabinet reads Lo? No. Wait until it reaches holding temperature, and only load food that is already heated to a safe temperature. ### What if Lo never goes away on my Hatco FSCD? Then the cabinet is not heating. A tripped high-limit, a blower motor or a heater can be the cause, and all of them are technician repairs. --- **[Read on the site: Hatco Lo: the display cabinet is still below 70°F](https://commercialappliancerepair.center/error-codes/hatco-lo/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
