Display shows F2; interior light or other auxiliary functions may not operate correctly.

Safety: Unplug the cooler before working on the light or wiring. LED modules operate at low voltage but are powered from mains circuitry.

Steps to address F2:

• Check light behavior: Note whether the interior light is stuck on, will not turn on, or flickers when F2 appears.
• Inspect LED module: Remove the light cover inside the cabinet and inspect the LED module for burn marks or discoloration.
• Check wiring: Follow the light wires to their connector. Look for pinched or cut wires, especially where they pass through the liner.
• Disconnect light module: With power unplugged, disconnect the LED module from the harness. Restore power briefly to see if F2 clears without the light connected (do this only if you are comfortable; otherwise, skip and call a technician).
• Replace faulty LED module: If F2 clears when the light is disconnected, replace the NewAir LED light module and reconnect.
• Evaluate control board: If F2 persists even with the light disconnected and wiring intact, the light driver on the main control board may be defective. Replace the NewAir main control board (PCB) as needed.

Note: Do not bypass or jumper light circuits; this can damage the control board and create a fire hazard.
