Freezer interior light does not turn on when door is opened, but cooling is normal.

Safety first: Unplug the freezer before replacing bulbs or accessing wiring.

Steps:

• Check door switch: Verify that the switch actuates properly. If the control panel responds to door opening (e.g., fan stops), the switch is likely good.
• Inspect light assembly: Remove the light lens and check for a replaceable bulb or LED module. Replace the LED light module or bulb if visibly burned or darkened.
• Check wiring: Ensure the light connector is firmly seated.
• Control board: If the light and wiring are good, the main control board may not be supplying power to the light circuit.
