Display shows CF; compressor does not start or stops shortly after starting.

Safety: Unplug the cooler before accessing the rear compartment. Moving fan blades and live wiring are hazardous.

Steps to address CF:

• Access condenser fan: Remove the rear lower panel to expose the condenser coil, fan, and compressor.
• Inspect fan area: Look for dust buildup, debris, or wires obstructing the fan blades. Clear any obstructions.
• Check fan operation: With the panel still off, briefly plug in the unit and observe whether the fan starts when the compressor runs. Unplug again after checking.
• Test fan motor: If the fan does not run, unplug the unit and check that the fan spins freely by hand. A stiff or seized fan indicates a bad motor.
• Check wiring and connector: Ensure the fan’s connector is fully seated on the harness and at the control board. Look for damaged wires.
• Replace fan motor: If the motor is seized or open-circuit on a resistance test, install a new NewAir condenser fan motor assembly.
• Reassemble and test: Reinstall the rear panel, restore power, and verify that the fan runs with the compressor and the CF code clears.

Note: If the fan runs but CF persists, the control board’s fan monitoring circuit may be faulty and the main control board may need replacement.
