Conversely, when the temperature reaches the preset cooling target, the thermostat signals the compressor to shut off, preventing excessive cooling. In this way, the thermostat plays a pivotal role in maintaining the consistent and optimal temperature required to keep your food fresh and safe.

Why It Fails: Thermostats can malfunction due to damaged wiring or issues with the contact assembly inside. They rely on a gas-filled tube to measure temperature, and if this tube develops a leak, the thermostat may inaccurately assess the temperature, causing cooling problems.

How to Fix It: To determine if your thermostat is faulty, follow these steps:

  1. Locate the thermostat inside your fridge.
  2. Rotate the thermostat from its lowest to highest setting; you should hear a click.
  3. If no click is heard, it may be defective.
  4. If there’s no click, use a multimeter to test the thermostat’s continuity.
  5. If no continuity is detected, replace the thermostat.

4. Faulty Control Board

The control board in your refrigerator serves as the central brain of the appliance, responsible for managing and coordinating the operation of all its components. It acts as a critical control hub that ensures the smooth functioning of your fridge. This sophisticated electronic board constantly monitors and regulates various functions, such as temperature control, defrost cycles, and fan operations.

It plays a pivotal role in maintaining the ideal conditions for food preservation. In case of malfunctions or errors, the control board can also display error codes or diagnostics to help technicians pinpoint and resolve issues efficiently, contributing to your refrigerator’s overall reliability and efficiency.

Why It Fails: Control boards can fail due to exposure to excessive heat, moisture, or manufacturing defects.

How to Fix It: If your control board is damaged, it must be replaced. However, testing all other fridge components before replacing the control board is wise, as it is less prone to failure.

5. Dirty Condenser Coils

Efficient cooling in your refrigerator hinges on the effectiveness of its condenser coils. These coils play a crucial role in refrigeration by transforming refrigerant from a gaseous state into a liquid form. This transformation occurs as the gaseous refrigerant circulates through the coils and encounters lower temperatures and higher pressure.

By releasing heat, the refrigerant changes into a liquid, thus allowing the refrigerator to maintain a lower temperature inside the unit. However, suppose the condenser coils become dirty or clogged with debris. In that case, they can’t dissipate heat efficiently, causing the fridge to work harder and become less energy-efficient, ultimately compromising its cooling performance.

Why It Fails: Dirt and dust can accumulate on the condenser coils over time, insulating them and hindering heat dissipation. This can cause your fridge to work harder and become less energy-efficient.

How to Fix It: Cleaning dirty condenser coils is a straightforward task:

  1. Unplug your fridge for safety.
