My Fridge is Too Cold

If your fridge is too cold and you find that you are freezing your tomatoes and salads the most likely cause of the problem is the thermostat. There are several possible reasons – the thermostat is not set correctly, the probe is not sensing correctly, or the thermostat is faulty.

First check the thermostat setting. Normally the higher the number the colder the fridge and the exact temperature they achieve varies considerably between manufacturers. Turn the thermostat to the lowest number and check to see if this raises the temperature in the fridge. If this makes no difference the next place to investigate is the thermostat probe.

Most thermostats on DC compressor driven fridges are mechanical and the sensing probe is a fixed length of capillary tube which attaches directly to the evaporator plate in the fridge (usually a white aluminum plate or box that produces the cold in the fridge).

The first thing to check is that the end of this capillary is touching the plate. As a general rule if the evaporator plate is sized correctly the plate will need to be at approx -8C to achieve a fridge temperature of +4C to +6C. Therefore, if the probe from the thermostat has come away for the plate it will be sensing the air temperature, not the temperature of the evaporator plate.

This will explain why your fridge too cold as it will only turn off when the fridge temperature is approx -8C, and all your finest salads are frozen solid. The probe is usually attached with a simple metal clip and you should be able to simply clip it back into place, on some models of fridge, there is a plate with a fixing screw to clamp it back onto the evaporator.

If you have checked the thermostat probe and it is installed correctly, the end touching the plate as it should, then you have isolated the problem to the actual thermostat being at fault. Replace the thermostat and your fridge will be back working correctly. If you find it to be too complicated, you can always call professional appliance repair NY service to repair the fridge.
