Deep freezers that do not cool properly can be caused by a number of different factors, such as the thermostat being set in the incorrect temperature position. The thermostat is a switch that regulates the temperature in your deep freezer. It is set to a certain temperature and when the freezer begins to warm up, it turns off the power going to the compressor until it cools down below that temperature again. If the thermostat is faulty, it will function incorrectly, leading to temperature issues within your deep freezer. A common reason for the thermostat setting to malfunction is that it has been knocked out of place by accident. To correct this problem, simply push the thermostat back into position. Another possibility is that the thermostat itself has become faulty and needs to be replaced.
