Common Causes of Freezers Not Defrosting Properly
When your freezer isn’t defrosting properly, it could be due to one or more of the following reasons:
- Faulty Defrost Timer: The defrost timer controls when the freezer enters its defrost cycle. If the timer isn’t functioning correctly, it may not activate the cycle when it’s needed.
- Malfunctioning Defrost Heater: The defrost heater melts any accumulated frost, but if it’s broken or malfunctioning, frost will continue to build up.
- Broken Defrost Thermostat: The thermostat senses the temperature inside the freezer and signals when to start the defrost cycle. A faulty thermostat can prevent the defrost cycle from starting or ending at the right time.
- Clogged Drain: If the defrost drain is blocked, the water from the melted frost can’t flow out, causing the frost to freeze back inside the freezer.
- Faulty Control Board: In some cases, the control board that regulates the freezer’s operations can be faulty, affecting the defrost cycle.
How to Fix a Freezer That Isn’t Defrosting Properly?
Test the Defrost Timer
The defrost timer is a key component in managing the defrost cycle. If the timer is stuck or broken, the freezer will not properly enter or exit the defrost cycle.
- Locate the timer: The defrost timer is usually located near the control panel or inside the freezer’s service panel. Refer to your freezer’s manual to find its exact location.
- Test the timer: Using a multimeter, test the defrost timer for continuity. If there’s no continuity when you rotate the timer, it may need to be replaced.
Inspect the Defrost Heater
The defrost heater is responsible for melting the ice that builds up inside the freezer. If it’s faulty, the freezer won’t defrost properly, and frost will continue to accumulate.
- Locate the heater: In most freezers, the defrost heater is located at the bottom of the evaporator coil.
- Check for visible damage: If the heater looks cracked or burnt, it will need to be replaced.
- Test the heater: Use a multimeter to check the continuity of the heater. If there’s no continuity, the heater is broken and should be replaced.
Check the Defrost Thermostat
The defrost thermostat monitors the temperature of the evaporator coils to determine when to initiate the defrost cycle. A malfunctioning thermostat will prevent the freezer from properly defrosting.
- Locate the thermostat: It’s typically mounted near the evaporator coils.
- Test the thermostat: Use a multimeter to test the thermostat for continuity. If the thermostat is not working properly, it should be replaced.
Clear the Defrost Drain
If the defrost drain is blocked, the water from the defrost cycle can’t flow out of the freezer, leading to ice buildup.
- Locate the drain: The defrost drain is usually located at the bottom of the freezer compartment.
- Unclog the drain: Use a small brush or a pipe cleaner to remove any debris or ice that’s blocking the drain. Pour warm water down the drain to ensure it flows freely.
Inspect the Control Board
If your freezer has a control board, it’s responsible for regulating the defrost cycle. A malfunctioning control board can prevent the freezer from entering the defrost cycle altogether.
- Inspect for visible damage: Check the control board for any burnt areas or signs of damage.
- Test the board: If you have the proper tools and knowledge, you can test the control board. Otherwise, it’s best to consult a professional to assess and replace the board if necessary.
