Display shows EC and the condenser fan at the back of the refrigerator may not run, causing the compressor to overheat and poor cooling.

Safety: Unplug the refrigerator before working at the rear. The compressor and condenser can be hot—allow them to cool.

Steps:

• 1. Access condenser fan: Remove the lower rear cover to expose the condenser coil and fan assembly.
• 2. Visual inspection: Check for dust, pet hair, or debris blocking the fan blades. Clean thoroughly with a soft brush and vacuum.
• 3. Spin test: Rotate the fan blades by hand. If they do not spin freely or feel rough, the motor bearings may be worn and the motor should be replaced.
• 4. Electrical test: With power disconnected, measure resistance across the fan motor terminals. An open circuit indicates a failed motor.
• 5. Check wiring: Inspect the harness from the fan to the main PCB for cuts, burns, or loose connectors. Repair as needed.
• 6. Replace fan motor: Install a new Haier-compatible condenser fan motor. Ensure the fan blade is correctly oriented and securely attached.

Tip: Keeping the condenser area clean improves efficiency and reduces compressor stress.
