A freezer decides when to cool by one of two means. Chests and simpler uprights use a mechanical thermostat: a dial wired to a thin capillary bulb clipped to the liner, which opens and closes a switch as the cabinet warms and cools. Newer uprights, columns and undercounter freezers use a thermistor, a sensor whose reading a control board compares with the setting. When either drifts, the freezer can run constantly and freeze everything to stone, or shut off too soon so the food sits a few degrees warmer than it should. A garage adds a twist: when the room itself falls near freezing, a thermostat in a warm-to-the-touch cabinet may barely call for cold, even though the food begins to soften. The technician compares the setting with a thermometer reading in the food, tests the thermostat or sensor at a known temperature, and replaces it, or recommends a garage kit or a different spot when the room is the real cause. How the visit goes ### What it usually costs Low to moderate · Thermostat, temperature sensor or garage kit A dial thermostat on a chest or a basic upright is inexpensive. A sensor on an electronic model, or a garage kit fitted to a freezer that lives in a cold room, adds a step for the part and the setup. ### Answers 5 problems Freezer Running Too Cold Freezer Runs All the Time · Freezer in the Garage Stopped Working · Standalone Freezer Not Freezing · Freezer Warming Up With Food Inside ### Comes up most on Upright freezer Chest freezer · Freezer column · Undercounter freezer ### Codes that lead here Power Failure!! · Temperature alarm message · Door alarm message · Abnormally high temperature Bertazzoni Power Failure!! on a freezer column after an outage. ## Freezer thermostat and temperature control repair, step by step. Watch the freezer cycle off and back on at the right point, and show you how to set it. 01 Compare what the control is set to with a thermometer reading taken in the middle of the food. 02 Check the dial and its switch on a mechanical model, or the sensor and its reading on an electronic one. 03 Look at the room: a garage below freezing or a hot utility room changes how the control behaves. 04 Replace the thermostat, the sensor or the knob, or fit the maker's garage kit where the model offers one. 05 Watch the freezer cycle off and back on at the right point, and show you how to set it. ## The problems it answers. 5 of them, from freezer running too cold to freezer warming up with food inside.

Zero degrees Fahrenheit or a little colder keeps frozen food safe and at its best. Check it with a thermometer set between packages in the middle of the freezer, not on the door, and give it a day to settle after any change. ### Why does my garage freezer quit working in winter? Many freezers are built for rooms that stay above about 40 °F. In a colder garage the thermostat may see little reason to run the compressor, or the oil in the compressor may thicken and resist starting. Some makers sell a garage kit or rate certain models for these rooms; otherwise, moving the freezer indoors is the lasting fix. ### Everything in my freezer is frozen rock hard. Is that a problem? Food is safe, but a freezer that never stops running wears its compressor and costs more to operate. If turning the setting warmer does not change anything, the thermostat or sensor is likely stuck and should be checked. --- **[Read on the site: Freezer Thermostat and Temperature Control Repair](https://freezerrepair.center/services/thermostat-and-temperature-control-repair/)** **[Book a visit with FreezerRepair.center](https://freezerrepair.center/schedule/)**
