Why Does It Fail?

Several factors can lead to compressor failure. Inadequate ventilation is a frequent culprit, causing the compressor to overheat and eventually break down. Another common reason is frost buildup on the coils, which can occur due to improper sealing or prolonged door openings.

How To Diagnose And Fix It

  • Check if the compressor is running by listening to a humming noise at the back of the fridge.
  • Ensure the refrigerator is plugged in and receiving power.
  • Feel for heat around the compressor; if it’s warm, it’s likely functioning.

To resolve the issue, start by addressing ventilation problems. Clear any obstructions around the fridge’s vents. If no blockages exist, defrosting the coils by unplugging the refrigerator for a few hours might be necessary. If the compressor is faulty, it’s a complex repair that is best left to experienced technicians.

2. Dirty Condenser Coils

Condenser coils are a vital part of a refrigerator’s cooling system, which releases heat from the appliance. When these coils accumulate dirt and debris over time, their efficiency is compromised, leading to a significant challenge in maintaining a cool temperature inside the fridge. As the coils become dirty, they struggle to release heat effectively, causing the refrigerator to work harder and longer to maintain the desired low temperature.

This increased workload can reduce cooling performance, increase energy consumption, and cause overheating issues. Regular cleaning and maintenance of the condenser coils are essential to ensure optimal cooling efficiency and prolong the refrigerator’s life.

Why Does It Happen?

Condenser coils accumulate dirt and debris over time, hindering their heat dissipation capability.

How To Address It

To clean the condenser coils, remove them from the back of the fridge and vacuum or brush away the accumulated dirt and debris. Replace them if needed, ensuring you select the correct size and type based on your fridge’s model.

3. Clogged Evaporator Coils

The evaporator coils, located within the refrigerator’s freezer section, serve a critical role in the cooling process by absorbing heat from the surrounding air. When these coils become clogged with dust, debris, or frost, their ability to effectively absorb heat is impaired. This obstruction hinders the freezer’s capacity to maintain a consistently cold temperature.

As the evaporator coils struggle to remove heat efficiently, the freezer works harder, resulting in inadequate cooling. It may lead to temperature fluctuations, ice buildup, and reduced overall freezing performance. Periodic cleaning and proper maintenance of these coils are essential to ensure optimal freezing conditions within the freezer.

Why Does It Occur?

Dust and debris buildup on the evaporator coils can hinder their heat absorption capabilities, causing the freezer to work inefficiently.

How To Resolve It

Cleaning the coils is the first step. Remove them, gently brush off any dirt or dust, or use a vacuum cleaner with a soft brush attachment. After cleaning, ensure the freezer door is sealed tightly. If cleaning doesn’t solve the problem, consider replacing the evaporator coils available at most hardware stores.

4. Faulty Condenser Fan Motor

The condenser fan motor draws air over the condenser coils and the compressor. A defective condenser fan motor can disrupt the cooling process.

Why Does It Fail?

The condenser fan motor can fail due to a defective capacitor or damaged fan blades.

How To Diagnose And Repair It

Check the evaporator coils in the freezer for frost buildup, and the condenser coils in the fridge for dirt. If these are not the issues, examine the condenser fan motor for defects. Replacing the condenser fan motor is a relatively straightforward DIY repair. Unplug the fridge, remove the screws holding the engine in place, replace the old machine with a new one, and reassemble.

5. Malfunctioning Evaporator Fan Motor

The evaporator fan motor circulates air over the evaporator coils within the freezer. A malfunctioning fan motor can lead to inadequate cooling in the freezer.

Malfunctioning Evaporator Fan Motor

Why Does It Fail?

Over time, the evaporator fan motor can wear out, reducing its efficiency.

Symptoms

Ineffective cooling in the freezer can be a sign of a faulty evaporator fan motor.

How To Diagnose And Replace It

Ensure power goes to the fan motor, and check the evaporator coils for frost buildup. Inspect the evaporator fan motor to see if these checks don’t reveal any issues. Replacing the evaporator fan motor is a manageable DIY task. Unplug the freezer, remove the old engine, install the new one, and reconnect the wires.

6. Main Control Board Problems

The main control board acts as the brain of your refrigerator. If it malfunctions, your fridge’s overall functionality will be compromised.
