Fridge Not Defrosting

What To Do If a Fridge Is Not Defrosting?

If you’ve stumbled upon a frosty spectacle inside your refrigerator, courtesy of a defroster malfunction, fear not. There are straightforward reasons for this predicament and equally uncomplicated remedies.

Much like various refrigerator issues, these are precisely the sort of challenges that FIX Appliances CA excels at resolving. Our adept team, honed expertise, and years of hands-on experience ensure that no refrigeration issue is beyond our capability to swiftly diagnose and effortlessly repair, regardless of its magnitude.

The Refrigerator Does Not Defrost

While the result of a properly defrosted fridge seems simple enough, the parts and processes of defrosting your fridge can be rather complex. Here are three reasons why your refrigerator won’t defrost.

Defrost Control Board Issue

This electronic board in your fridge directs the fridge on how often to run the automatic defrost cycle. The fridge will not go into a defrost cycle when this board has issues or fails altogether.

If your refrigerator and freezer never go through a defrost cycle, the result will be that you will find your refrigerator and freezer not defrosting.

Defrost Sensor and Thermal Fuse Issues

Your defrost sensor system monitors the temperature of your evaporator. This part has a fuse that acts as a backup in case the sensor fails.

Should the sensor neglect to deactivate the defrost heater, the thermal fuse will blow, compelling the heater to shut down. Consequently, your defrost heater becomes non-operational, leading to the undesirable outcome of your refrigerator failing to defrost.

Defrost Timer Issue

The defrost timer orchestrates the activation of the defrost heater multiple times each day, eradicating any frost buildup on the evaporator. A defective timer may fail to progress into the defrost cycle or transmit power to the defrost heater during said cycle.

To assess the timer’s functionality, manually advance it into the defrost cycle. At this juncture, the compressor should cease operation, and the heater should commence.

If the timer fails to supply power to the heater or shift out of the defrost cycle within 30 minutes, a malfunction in the timer becomes evident, potentially causing your refrigerator’s defrost failure.

The Fridge Is Not Defrosting. What To Do?

While it’s uncommon for a refrigerator to cease defrosting, the causes are typically straightforward. Fortunately, troubleshooting these issues is just as uncomplicated.

Now that you understand the reasons behind your refrigerator’s defrost system malfunction, let us guide you through the steps to rectify these problems and have your refrigerator defrosting efficiently again.

Defrost Control Board Repair

When dealing with a possible issue with your defrost control board, it is best to eliminate the simple issues first before jumping to the control board. The first steps are to check the function of both the defrost heater and the defrost thermostat.

If these components are in good working order, the likely culprit is a defective defrost control board. In such instances, the best course of action is to replace the board.

Locating and installing a replacement for your unit is usually a straightforward process. If you feel this may surpass your abilities, entrust the delicate task to the professionals at FIX Appliances CA.

Defrost Sensor and Thermal Fuse Repair

A thermal fuse of the defrost sensor cannot be reset. If the thermal fuse blows, you must replace the defrost sensor. To determine which part is faulty, you must use a multimeter to test both parts. If either of the parts lacks continuity, it is time to replace the defrost sensor.

Defrost Timer Repair

A faulty timer is one of the most common reasons your fridge may not defrost. Issues with these parts are easy to diagnose, but the timer itself cannot easily be repaired. The best solution is to replace the timer. Timers for modern refrigerators are quite easy to find online, yet their replacement can be a bit tedious and time-consuming for do-it-yourselfers.
