How to Fix / Troubleshooting

Safety first: Unplug the freezer before accessing the fan area.

Access fan: Remove baskets and the inner rear panel to expose the evaporator fan assembly.
Check for ice: Look for ice buildup around the fan blades. If present, fully defrost the freezer and ensure the defrost system is working.
Inspect fan blade: Ensure the blade is firmly attached to the motor shaft and not contacting the shroud. Adjust as needed.
Spin test: Spin the fan by hand. If it feels rough, wobbly, or squeals, the motor bearings are likely worn.
Replace fan motor: Install a Hisense-compatible evaporator fan motor and reattach the blade and shroud. Route wires away from moving parts.

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

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