7 Reasons Why Your Sub-Zero Refrigerator Is Making A Loud Noise

Sub-Zero’s near-silent operation is part of its superior cooling technology. So, why is my Sub-Zero refrigerator making such a loud racket? A knocking noise may be heard if the evaporator fan blade is damaged or obstructed. Learn how to fix noisy refrigerator noises so your Sub-Zero can once again be quiet.

1. Obstructed Fan Blade

If the fan blade is bent or damaged, it will make a noise as it spins. The fan motor may also be noisy if the fan blade is obstructed. Check the evaporator fan blade and motor for obstructions.

2. Damaged Fan Blade

The fan blades are delicate and can be easily damaged. If you hear a rattling noise, it is likely that the fan blade is damaged and needs to be replaced.

3. Loose Screws

If you hear a rattling noise coming from your Sub-Zero refrigerator, one of the screws inside the unit has likely become loose. Tighten all screws inside the unit to see if this fixes the problem.

4. Compressor Problems

If the compressor is not working properly, it can make a knocking noise. Check to see if the compressor is running and that there is no ice buildup around it. If the compressor is not running, it may need to be replaced.

5. Dirty Condenser Coils

If the condenser coils are dirty, they will not be able to dissipate heat properly, and the compressor will have to work harder. This can cause the compressor to make noise. Clean the condenser coils with a coil cleaning brush to see if this fixes the problem.

6. Accumulated Ice

If there is ice buildup inside the unit, it can cause the fan blades to hit the ice and make noise. Check for ice buildup and defrost the unit if necessary.

7. Worn Out Parts

If your Sub-Zero refrigerator is making noises and none of the above solutions fix the problem, it is likely that one of the parts inside the unit has worn out and needs to be replaced. Contact a Sub-Zero service technician to diagnose the problem and recommend the best course of action.

Noisy refrigerators can be a nuisance. But with a little troubleshooting, you can often fix the problem yourself. If your Sub-Zero refrigerator makes noise, check the fan blades, motor, and compressor for obstructions or damage. Also, make sure that all screws are tight and no ice buildup inside the unit. If the problem persists, contact a Sub-Zero service technician for assistance.
