2. Safety Information

• Disconnect Power: Always ensure the appliance (microwave oven or refrigerator) is completely disconnected from its power source before attempting any installation or replacement. Failure to do so can result in electric shock or injury.

4. Installation Instructions

Follow these steps to replace the bulb in your microwave oven or refrigerator:

1. Power Disconnection: Unplug the appliance from the electrical outlet to ensure no power is supplied.
2. Access the Bulb: Locate the bulb compartment. This may involve removing a cover panel, a grill, or accessing it from the back of the appliance. Refer to your appliance's specific user manual for exact instructions on accessing the bulb.
3. Remove Old Bulb: Carefully remove the old bulb. It may be held in place by screws, clips, or a twist-and-pull mechanism. Note the orientation of the old bulb for correct installation of the new one.
4. Install New Bulb: Insert the LICHIFIT replacement bulb into the socket. Ensure the metal prongs align correctly and the bulb is securely seated. This model is a Straight Bend type; ensure it matches the original bulb's configuration.
5. Secure Bulb and Cover: Re-secure any screws or clips that hold the bulb in place. Replace any cover panels or grills that were removed.
6. Restore Power: Plug the appliance back into the electrical outlet.
7. Test: Test the new bulb by opening the appliance door or activating the light function.

5. Operation

The LICHIFIT replacement bulb operates automatically with your appliance. In microwave ovens, the light typically illuminates when the door is opened or during cooking cycles. In refrigerators, it illuminates when the door is opened.

6. Maintenance

• Cleaning: Keep the bulb and its surrounding area clean and free from dust or debris. Ensure the appliance is unplugged before cleaning. Use a dry, soft cloth to wipe the bulb if necessary.
• Replacement: Replace the bulb when it burns out. Follow the installation instructions provided in Section 4.

7. Troubleshooting

• Bulb Does Not Light Up:
  • Ensure the appliance is properly plugged into a working electrical outlet.
  • Verify that the bulb is correctly installed and seated firmly in its socket.
  • Check if the bulb filament is intact. If broken, the bulb needs replacement.
  • Confirm that the appliance's internal light switch (often activated by the door) is functioning correctly.
• Bulb is Dim:
  • This bulb is rated for 230V/250V. If your appliance operates on a 100-120V electrical system (common in North America), the bulb will appear significantly dimmer than its rated brightness. This is expected behavior due to voltage incompatibility and is not a defect of the bulb. For optimal brightness, ensure your appliance's voltage matches the bulb's rating.
