Loud humming, top Refrigerator warm - Fan motor issue (condenser or evaporator)

What does Loud humming (stops with door open), top fridge warm mean?

The Refrigerator emits a loud humming noise that immediately stops when the Refrigerator door is opened. Concurrently, the top right section of the Refrigerator is not cooling properly, while the freezer and bottom drawers operate normally. This behavior strongly suggests a fan-related issue.

• Evaporator fan motor malfunction (fan usually stops with door open if faulty or noisy)
• Ice buildup on the evaporator fan blades or housing
• Items obstructing the evaporator fan
• Condenser fan issue (less likely if noise stops with Refrigerator door open)

Click steps to track your progress.

1. 1

   Unplug the Refrigerator and perform a thorough manual defrost, specifically focusing on the evaporator area behind the back panel in the top Refrigerator section.

2. 2

   After defrosting, check if the evaporator fan is clear of ice and spins freely.

3. 3

   Ensure no food items or packaging are blocking the air vents or obstructing the fan's operation.

4. 4

   If the humming noise and cooling issue persist, a service technician should test the evaporator fan motor for failure.
