Is Your Commercial Refrigerator Thermostat Working Properly?, Honolulu, Hawaii

To run a successful restaurant or event center, you need to have fully functional commercial kitchen equipment. Routinely checking components like the refrigerator thermostat ensures your food is fresh and safe to serve. The refrigerator is one of the most important appliances in a commercial kitchen, so it’s necessary to know how to measure the temperature and determine when to replace the gauge.

A Guide to Commercial Kitchen Equipment Thermostats

Why Is the Thermostat So Important?

commercial kitchen equipment Honolulu HIEverything stored in your refrigerator and freezer needs to be kept at a specific temperature to comply with local health codes. Food that is not kept at these temperatures can spoil, potentially making diners sick and wasting money. If the temperature gauges on your commercial kitchen equipment are not working, the food will either be too warm and unsafe to serve, or too cold and difficult to thaw and cook.

How Do I Inspect It?

One of the easiest ways to test the refrigerator and freezer temperatures is to leave a small thermometer inside for an hour. Depending on the unit, the ideal temperature will be between -10 and 38 degrees Fahrenheit. Refrigerators should be below 38 degrees, and freezers should be below 5. To inspect the gauge directly, unplug the appliance to avoid shocks, remove the panel from the thermostat, and expose its two wires. Follow the instructions on a continuity tester to determine whether the thermostat has a closed circuit. If the circuit is closed, there is no problem with the unit.

How Do I Know When It Needs to Be Replaced?

If your continuity tester shows that the circuit is not closed, then the thermostat is not working properly. Although commercial refrigeration equipment gauges can be repaired, replacing them is often the more cost-effective approach. This ensures the unit will work the way it’s supposed to, so your refrigerator and food are at the correct temperature.
