1. Power supply and plug check first need to check the freezer power supply and plug is normal. If the power supply and plugs are faulty, the freezer will not work properly. You can use a multimeter to test the power supply and plugs for problems and replace or repair them accordingly.
2. Thermostat AdjustmentIf the inside of the freezer refuses to cool, you need to check the location and adjustment of the thermostat. Typically, the thermostat should be placed inside the freezer to fully feel the temperature changes. When adjusting the thermostat, the temperature inside the freezer should be brought down first and then the thermostat should be gradually turned up until the proper temperature is reached.
3. Cleaning and MaintenanceFreezers need to be cleaned and maintained on a regular basis, which is one of the best ways to prevent breakdowns from occurring. Cleaning the interior and exterior, cleaning the refrigerator tray and offset plate, cleaning parts, etc. can effectively extend the service life of the freezer.
