How to Reset Defrost Timer on Fridge

Resetting the defrost timer on your fridge can help resolve issues with excessive frost build-up or temperature imbalances. The defrost timer is responsible for turning on the defrost heater several times a day to prevent frost from accumulating on the evaporator coils.

If you're experiencing problems where your fridge isn't defrosting as it should, or if you notice consistent ice build-up, it may be necessary to reset the defrost timer. Below, we'll guide you through the steps to reset the defrost timer on your fridge.

Determining the Type of Defrost Timer

Before resetting the defrost timer, it's important to identify the type of defrost system your fridge uses. There are mainly two types: mechanical defrost timers and electronic defrost timers.

1. Mechanical Defrost Timer: A mechanical defrost timer will have a rotary dial with a small motor and a numbered scale with different settings. The dial continuously rotates for the freezer's regular operational cycles.

2. Electronic Defrost Timer: An electronic defrost timer is composed of an electronic control board usually located at the back of the fridge. It uses a microprocessor to time the defrost cycles.

Resetting a Mechanical Defrost Timer

If you have a mechanical defrost timer, follow these steps to reset it:

1. Locate the defrost timer: Typically, you can find it by looking behind the kick plate or by removing the control panel in the fridge.
2. Identify the defrost timer's advance screw: This small screw can be turned using a flat-head screwdriver.
3. Unplug the fridge: For safety purposes, it is recommended to unplug the fridge from the power outlet.
4. Rotate the defrost timer: Turn the defrost timer using the flat-head screwdriver and rotate it clockwise until it clicks. This should initiate the defrost cycle manually.
5. Plug the fridge back in: After resetting the defrost timer, plug the fridge back into the power outlet and wait for it to restart.

By following these steps, you have successfully reset the mechanical defrost timer on your fridge.

Resetting an Electronic Defrost Timer

If your fridge has an electronic defrost timer, the reset process might differ. Generally, you'll need to follow these steps:

1. Locate the electronic control board: Commonly found at the back of the fridge, the control board is usually enclosed in a protective cover.
2. Unplug the fridge: Always unplug the fridge from the power outlet before proceeding.
3. Reset the control board: In most cases, there will be a reset button on the control board. Press and hold the reset button for 10-15 seconds to reset the defrost timer.
4. Plug the fridge back in: Once the reset is complete, plug the fridge back into the power outlet and observe if the defrost cycle initiates.

By following these steps, you should have successfully reset the electronic defrost timer on your fridge.

Conclusion

Resetting the defrost timer on your fridge can help solve issues related to frost build-up and temperature imbalances. Depending on the type of defrost timer your fridge uses, either a mechanical or electronic reset method can be applied. Always ensure to unplug the fridge before attempting any reset procedure to ensure safety.
