A fridge that is not defrosting can be a frustrating and potentially costly problem to have. Not only can it cause damage to your food, but it can also lead to wasted time and money.
In this article, we will discuss the common causes of a fridge not defrosting and provide solutions for each.
Causes of a Fridge Not Defrosting
Faulty Defrost Timer
One of the most common causes of a fridge not defrosting is a faulty defrost timer. The defrost timer is responsible for regulating the defrost cycle of the fridge. If the timer is not working properly, it may cause the fridge to not defrost. To fix this problem, you will need to have the defrost timer repaired or replaced.
Faulty Defrost Thermostat
Another common cause of a fridge not defrosting is a faulty defrost thermostat. The defrost thermostat is responsible for sensing the temperature inside the fridge and activating the defrost cycle. If the thermostat is not working properly, it may cause the fridge to not defrost. To fix this problem, you will need to have the defrost thermostat repaired or replaced.
Clogged Drain Line
A clogged drain line can cause water to build up in the fridge and prevent it from defrosting properly. This can happen due to food debris or other materials clogging the drain. To fix this problem, you will need to clean the drain line.
Dirty Evaporator Coils
Dirty evaporator coils can prevent the fridge from defrosting properly. The evaporator coils are responsible for absorbing heat from the fridge, and when they are dirty, they cannot function properly. To fix this problem, you will need to clean the evaporator coils.
Improper leveling
If the fridge is not level, the defrost cycle may not function properly, causing the fridge to not defrost. To fix this problem, you will need to level the fridge.
