Kenmore Refrigerator: humming sound
What is this symptom?
Experiencing a humming sound from your Kenmore refrigerator? This low-level buzzing may indicate normal compressor operation or issues with the ice maker. It's often more noticeable in quiet spaces and can vary with the fridge's load and temperature. Understanding the cause can help you determine the right solution, whether it's a simple DIY fix or a professional repair.
Important Tips for Kenmore Models
- Ice maker water valve and ice maker assembly can cause buzzing/humming when malfunctioning or under water supply pressure
Possible Causes
Normal compressor operation (low humming)
How to Identify: Steady low hum that corresponds with compressor cycling; typical during cooling but louder than before or noticed in quiet environments
Part: Compressor
Ice maker water valve or mechanism humming
How to Identify: Humming correlated with ice maker fill cycles or water supply pressure issues; stops when ice maker disabled
Part: Ice maker assembly / water inlet valve
Installation vibration or lack of level
How to Identify: Vibration noise transmitted to floor or nearby objects; reduced when leveling or adding anti-vibration mat
Part: Installation/leveling feet
DIY Solutions
Clean condenser coils and fan
- Unplug refrigerator
- Move fridge away from wall to access rear
- Use vacuum and brush to remove dust from condenser coils and fan area
- Ensure fan blades are free to spin and no debris remains
- Push fridge back and plug in
Level refrigerator and reduce vibration
- Place level on top of fridge to check tilt
- Adjust leveling feet until fridge is stable and level
- Place anti‑vibration mat under feet if needed to reduce transmitted vibration
Inspect ice maker water supply and disable if needed
- Locate ice maker water valve and supply line
- Check for kinks/obstructions and correct water pressure issues
- If unnecessary, turn off ice maker and observe if humming stops

User Suggested Solutions
-
Check for ice buildup around the evaporator fan. Unplug the refrigerator, remove any ice, and ensure the fan is unobstructed.
-
Listen for the compressor sound. If it is running without any unusual noises, it may just be normal operation. If the sound is excessive, consider consulting a professional.
