Why is My Fridge Getting Too Cold?

A refrigerator must operate quietly. It is important to check its components if you want to avoid a temperature failure and your fridge producing too much cold.

Air circulates freely in a refrigerator: it is diffused inside the appliance by an evaporator. Cold air sinks, while hot air rises: this is why food must be stored in different areas of the fridge. The more fragile foods, which must be kept longer, are placed at the bottom and the others higher.

Your refrigerator is a crucial component of your kitchen, maintaining the freshness and quality of your food. Ideally, it should keep a consistent temperature to prevent spoilage. However, sometimes, you may find your refrigerator becoming too cold, even freezing your produce or liquids. This issue can be just as problematic as a warm fridge. In this article, we will delve into some common reasons your fridge might be getting too cold and some potential solutions.

Why is My Fridge Getting Too Cold?

1. Incorrect Temperature Settings

One of the simplest reasons your fridge might be too cold is due to incorrect temperature settings. The optimal temperature range for your fridge should be between 37-40 degrees Fahrenheit (3-4 degrees Celsius), while the freezer should be at 0 degrees Fahrenheit (-18 degrees Celsius). Always check your temperature settings first, as they could have been accidentally adjusted.

2. Malfunctioning Thermostat

A fridge’s thermostat regulates the appliance’s temperature by triggering the compressor to start or stop. If the thermostat is faulty, it may incorrectly read the temperature inside, causing it to cool excessively. If you suspect a malfunctioning thermostat, you may need to have it replaced.

3. Faulty Temperature Control Board

The temperature control board provides voltage to the compressor and fan motors. If it’s malfunctioning, it could send continuous voltage, causing the fridge to cool too much. Replacing a defective temperature control board usually requires professional assistance.

4. Damper Control Assembly Issue

The damper control assembly opens and closes to let the proper amount of cold air into the refrigerator compartment from the freezer. If it gets stuck in the open position, it may let in too much cold air, causing the fridge to become too cold. If the damper is not closing properly, it may need to be repaired or replaced.

5. Defective Thermistor

The thermistor monitors the refrigerator’s temperature and sends the reading to the control board, which regulates power to the compressor and evaporator fan based on the thermistor readings. A defective thermistor may send incorrect readings to the control board, resulting in overcooling. You will need a multimeter to test the thermistor for continuity – a continuous electrical path present in the part. If the thermistor does not have continuity, or the reading is incorrect, you will need to replace it.

6. Problems with the Defrost System

If the defrost heater assembly or defrost thermostat fails, the defrost system will not work, and frost will continue to accumulate on the coils, leading to colder temperatures. These components will need to be tested and replaced if found to be faulty.

In conclusion, a refrigerator that is too cold can be just as problematic as one that is not cold enough. Regular maintenance and an understanding of the possible causes of temperature fluctuations can go a long way toward prolonging the life of your refrigerator. Always remember to consult with a professional if you’re unsure about diagnosing or fixing a problem. It’s better to be safe and maintain the longevity and efficiency of your appliance.
