A healthy cabinet cycles on and off. When the Traulsen control sees the compressor run past 24 hours, it shows RUN ERR. Traulsen's own list of reasons for long run times starts with doors not closing, a dirty condenser and an iced coil. Traulsen commercial appliance display · also shown as RUN What to do when RUN ERR shows on the commercial appliance ### Kind of code Compressor and cooling The unit is running but not moving heat out of the box the way it should. On a walk-in that is often a condensing unit on the roof choking on cottonwood or grease, a condenser fan that stopped, an evaporator fan or defrost heater that failed so the coil iced solid, or a slow refrigerant leak; a reach-in adds a door gasket or heater that lets warm air in. Cleaning the condenser face with the power off and checking that the doors close are fair first steps; the refrigerant circuit, the compressor and every line stay with a technician. ### Usually leads to Walk-in cooler repair Walk-in coolers and freezers back to temperature: evaporators, fans, defrost, drain heaters, condensing units and doors. ### 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 Traulsen A Traulsen cabinet that starts to drift gets its visit as soon as the food inside has a safe place to go. ### Source Traulsen All Series quick reference guide, owner's manual TR35924 rev.

Check every door and drawer for a proper close. If it comes back, it needs a visit. ### Why is my Traulsen running all the time? Traulsen's guide lists doors not closing, a dirty condenser or filter, and an iced evaporator coil. Check those three before anything else. ### Does RUN ERR on a Traulsen mean it is low on refrigerant? It can, but that is only one possibility. A technician rules out airflow and door problems before any work on the sealed system. ### Is RUN ERR on a Traulsen urgent? It is if the food is warming. Log temperatures and book a visit the same day if they climb. --- **[Read on the site: Traulsen RUN ERR: the compressor has run for a whole day](https://commercialappliancerepair.center/error-codes/traulsen-run-err/)** **[Book a visit with CommercialApplianceRepair.center](https://commercialappliancerepair.center/schedule/)**
