By following these steps, you can fix a faulty fan motor in your fridge freezer and enjoy a quieter appliance.
Blocked Air Vent
If your fridge freezer is making a lot of noise and not defrosting properly, one of the possible causes could be a blocked air vent. The air vent is responsible for allowing air to circulate throughout the appliance, ensuring that the temperature inside remains consistent and preventing ice buildup.
To fix a blocked air vent, follow these steps:
- Unplug the fridge freezer from the power source.
- Locate the air vent, which is usually found in the back of the freezer compartment.
