Refrigerator Making a Loud Noise? Common Causes and Fixes
A refrigerator making a loud noise usually points to one of the fans. A hum, buzz, or rattle often means a worn fan motor or a loose mount. Therefore, check the condenser and evaporator fans first. Below, we list the parts to inspect.
Parts to inspect for a refrigerator making loud noise problem
1. Condenser Fan Motor
The condenser fan pulls air across the coils to shed heat from the system. When it slows or stops, the fridge cannot cool and the compressor runs hot. First, clear any dust or debris from the fan blade. Then test the motor, and replace it if it does not spin freely or run.
2. Evaporator Fan Motor
The evaporator fan blows cold air off the freezer coil and into the cabinet. When it fails, the freezer may stay cold while the fresh food side turns warm. Also, a worn motor often squeals or clicks. So test the motor and replace it if it is noisy or dead.
3. Evaporator Fan Motor Grommet
The grommets are small rubber mounts that hold the evaporator fan and dampen its vibration. When they harden or slip, the fan rattles against the housing. Therefore, check the grommets for cracks and a snug fit. Replace them to quiet the noise.
Where refrigerator noise usually comes from
Most refrigerator noise starts at a fan. The condenser fan sits near the compressor at the back, while the evaporator fan hides behind the freezer wall. So a rattle from the rear points to the condenser fan, and a squeal from inside the freezer points to the evaporator fan. Locate the sound first, then inspect that fan.
