How to Fix / Troubleshooting

Safety first: Disconnect power before removing panels or touching fan wiring.

Steps:

Listen for fan: With the unit powered (before unplugging), close doors and listen for the freezer fan running. If silent or intermittent, suspect the fan.
Access freezer evaporator: Unplug the refrigerator. Remove freezer drawers and the rear interior panel to expose the evaporator coil and fan.
Check for ice buildup: If the fan blades are encased in ice, defrost the area completely using a hair dryer on low or by leaving the unit unplugged with doors open. Do not chip ice with tools.
Inspect fan motor: Spin the fan blades by hand; they should move freely. If stiff, noisy, or seized, replace the freezer evaporator fan motor.
Verify air ducts: Ensure the air channel leading to the ice room is not blocked by ice or debris. Clear any obstructions.

After repair, reassemble panels, restore power, and allow several hours for the ice room to cool and resume ice production.

Ice production slow or stopped; refrigerator shows 21E fan error, often affecting ice room cooling.
