A reach-in that's running warm in the middle of service is a food safety problem and a money problem at the same time. Here's what your staff can check in a few minutes, and when to call.
First, protect the product
Check the temperature with a probe thermometer, not just the unit's display. Food safety guidance generally calls for refrigerated food at 41°F or below. If the unit is above that, move what you can to another cooler or a walk-in, and note the time and temperatures for your records.
Quick checks
- The door. Does it close by itself and seal all the way around? A torn or flattened gasket, a sagging door, or a pan sticking out lets warm air pour in. Close a dollar bill in the door: if it slides out easily, that spot isn't sealing.
- Airflow inside. Product stacked against the back wall or the fan cover blocks the cold air. Leave space around the evaporator fan.
- The condenser. Usually behind a grille at the bottom or top. If it's matted with dust and grease, the unit can't get rid of heat. Many units run warm for exactly this reason.
- Around the unit. Is it jammed against a wall or next to a fryer or oven? It needs room to breathe and can't keep up next to a heat source.
- The setting. Has someone turned the control?
- Ice on the evaporator (behind the panel inside, if you can see it): heavy ice means a defrost or airflow problem.
Prep tables have their own weak spot: the lids over the rail. Leaving them open between orders lets the top run warm.
When to call
- It's still above 41°F after the checks above
- The compressor is running constantly, or clicking on and off
- The evaporator is iced over
- Water is pooling inside or under the unit
- You hear new grinding, rattling or squealing
Keeping it from happening
Most reach-in breakdowns trace back to a dirty condenser or a door that doesn't seal. Regular cleaning of the condenser, gasket checks and a look at refrigerant operation catch most of them early. That's what a commercial maintenance plan is for.
