E6 displayed, fan does not run or runs erratically, unit overheats or shuts down quickly.

Safety first: Unplug the unit before accessing the rear panel or fan area. Beware of sharp metal edges.

• Inspect airflow: Check that the rear grille and side vents are not blocked by dust, packaging, or walls. Clean any lint or dust buildup with a soft brush or vacuum.
• Check fan movement: Remove the rear cover to access the condenser fan. Spin the fan blades by hand; they should rotate freely without grinding or sticking. Remove any debris caught in the blades.
• Check wiring: Inspect the fan motor connector and wiring harness to the control PCB. Reseat the connector and look for damaged insulation.
• Test the fan motor: With a multimeter, measure the resistance of the fan motor windings. An open circuit indicates a failed motor. If you have the correct specifications, you can briefly power the fan directly (using the rated voltage) to confirm operation.
• Replace components: If the fan motor is defective, replace it with a compatible Severin condenser fan motor. If the motor is good but never receives voltage during operation, the control PCB fan driver or relay may be faulty and require replacement.
