The acoustic fiber panel located at the back of your Whirlpool, Maytag, or KitchenAid refrigerator helps reduce noise and vibration from the compressor. Over time, this material can wear out or become damaged. If your refrigerator is making more noise than usual or the fiber looks worn, it may be time for a replacement.
This is a simple repair you can do at home with a few basic tools. Follow the steps below to remove the old fiber panel and install a new one.
Confirm Part Compatibility
Before replacing the acoustic fiber, make sure the part you have matches your refrigerator model. Use only an OEM (original equipment manufacturer) part that is designed for your unit.
To find your model number, check the following locations:
- Inside the refrigerator, usually along the side wall or ceiling
- On the back panel of the fridge, near the bottom
- On the side or bottom edge of the door
Once you locate the model number, write it down or take a photo for reference when buying or confirming the replacement part.

Knowing when to replace the acoustic fiber can help you act before more serious problems develop. Watch for these signs:
- Louder-than-usual humming or buzzing from the back of the fridge
- Visible cracks, tears, or crumbling in the fiber material
- Loose insulation pieces around the compressor area
- A sudden drop in cooling performance or longer cooling cycles
- Strange vibrations or shaking when the compressor starts
- Residue or sticky patches where the fiber used to be

General Refrigerator Maintenance Tips
Replacing the acoustic fiber is a good opportunity to take care of other basic maintenance tasks. These simple checks can help extend the life of your refrigerator and improve its performance:
- Clean Regularly: Throw out expired items and clean the inside of the fridge each month. Use warm, soapy water to clean shelves, drawers, and bins. Dry all surfaces before putting items back
- Inspect Door Seals: Check for gaps, tears, or wear on the door gaskets. Replace them if needed to help maintain proper cooling
- Check Temperature Settings: Set the refrigerator to 37 to 40°F and the freezer to 0°F
- Replace Water Filters: Change the water filter every 6 to 12 months if your unit has a dispenser or ice maker
- Clean Condenser Coils: Every six months, unplug the refrigerator and clean the coils with a soft brush or vacuum attachment. This helps keep airflow strong and prevents overheating
- Sanitize Touch Points: Wipe down the door handles, dispenser buttons, and drip tray with disinfectant to reduce bacteria buildup
