What you Need to do When Your Fridge’s Defrosting System Fails

A malfunctioning defrosting system in your refrigerator can quickly turn into a chilling problem. When the frost builds up unchecked, it can affect the efficiency of your fridge, leading to potential food spoilage and increased energy bills. In this blog post, we’ll delve into the common causes of a defrosting system failure and how you can troubleshoot the issue.

Identifying the Problem: The first sign of a defrosting system failure is often the accumulation of frost or ice inside the freezer compartment. If you notice frost building up despite regularly defrosting the fridge, it’s likely that the automatic defrost system is not functioning correctly. Additionally, if you hear unusual noises or notice temperature fluctuations in the fridge, these could also be indicators of a malfunctioning defrosting system.

Why Defrosting system was not working Happen

Several components contribute to the proper functioning of the defrosting system, including the defrost heater, defrost thermostat, and defrost timer or control board. Any malfunction in these parts can disrupt the defrosting process and lead to frost buildup. Common causes of a defrosting system failure include:

  1. Defective Defrost Heater: The defrost heater is responsible for melting the frost on the evaporator coils. If the heater fails, frost will continue to accumulate, impairing the fridge’s cooling efficiency.
  2. Faulty Defrost Thermostat: The defrost thermostat monitors the temperature of the evaporator coils. If it’s defective, it may not signal the heater to activate, resulting in frost buildup.
  3. Malfunctioning Defrost Timer or Control Board: The defrost timer or control board regulates the frequency and duration of the defrost cycle. A malfunction in these components can disrupt the timing of the defrost cycle, leading to excessive frost buildup.

What Necessary Step you should take for freezer system Working Again

If you suspect that your fridge’s defrosting system is not working, here are some steps you can take to troubleshoot the issue:

  1. Manual Defrost: Start by manually defrosting the fridge to remove any existing frost buildup. This involves unplugging the fridge and allowing the ice to melt completely.
  2. Check the Defrost Heater: Use a multimeter to test the continuity of the defrost heater. If it’s defective, replace it with a new one.
  3. Test the Defrost Thermostat: Check the continuity of the defrost thermostat using a multimeter. If it’s faulty, replace it as well.
  4. Inspect the Defrost Timer or Control Board: If the previous steps don’t resolve the issue, inspect the defrost timer or control board for any visible signs of damage or malfunction. Replace these components if necessary.
