How to Fix / Troubleshooting

Safety warning: Unplug the freezer before removing interior panels. Fan blades and metal edges can be sharp.

Steps to fix squealing/chirping:

Defrost interior: If heavy frost is present, unplug the unit and allow it to defrost fully. This may resolve ice-related noises.
Access evaporator fan: Remove baskets and the rear interior panel to expose the fan and evaporator.
Inspect fan area: Check for ice buildup around the fan shroud or blades. Remove ice with warm water and towels.
Check fan blade: Ensure the blade is firmly attached to the motor shaft and not rubbing on the shroud. Adjust as needed.
Replace fan motor if noisy: If the squeal persists and the motor feels rough when spun by hand, replace the Costway evaporator fan motor and transfer the blade if separate.

Note: Do not lubricate sealed fan motors; replacement is the proper repair.

Freezer makes a high-pitched squealing or chirping noise from inside the cabinet.
