Safety: Unplug the freezer before accessing the evaporator area. Fan blades and metal edges can be sharp.

Steps:

Listen for fan: When powered, you should normally hear the evaporator fan running with the door closed. If silent, proceed with checks after unplugging.
Defrost and access: Remove baskets and the rear interior panel. If heavy ice is present around the fan, allow it to melt before forcing the panel off.
Inspect fan: Check if the fan blade is broken, loose, or jammed by ice. Spin it by hand; it should rotate freely.
Check wiring: Ensure the fan motor connector is secure and wires are intact.
Test motor: Disconnect the fan and measure resistance across the motor leads. An open reading indicates a failed motor.
Replace assembly: Install a new evaporator fan motor (and fan blade if damaged). Route wiring away from moving parts.
Reassemble and test: Reinstall the rear panel, restore power, and confirm that E9 clears and air circulates inside the freezer.

Vissani freezer shows E9; interior evaporator fan may not run, causing uneven temperatures and frost on back wall.
