Follow these steps to replace your existing keypad cover with the new LiftMaster 41D621 cover.
3.1 Tools Required
- Small flathead screwdriver (optional, for prying if needed)
3.2 Replacement Procedure
- Open the Existing Cover: Gently lift the existing keypad cover to its fully open position.
- Identify Hinge Pins: Observe the hinge mechanism where the cover attaches to the keypad base. There are typically small pins or tabs that hold the cover in place.
- Remove Old Cover: Carefully disengage the old cover from the hinge pins. This may involve gently prying the cover away from the base at the hinge points. Apply minimal force to avoid damaging the keypad base.
- Align New Cover: Take the new LiftMaster 41D621 replacement cover. Align its hinge points with the corresponding slots or pins on the keypad base.
- Attach New Cover: Press the new cover firmly onto the hinge pins until it snaps securely into place. Ensure both sides of the hinge are properly seated.
- Test Functionality: Open and close the new cover several times to ensure it moves smoothly and closes completely, providing adequate protection to the keypad.
4. Operation
Once installed, the replacement cover operates identically to the original. Simply lift the cover to access the keypad buttons for entering your code. Close the cover when not in use to protect the keypad from weather and debris.
- Opening: Gently lift the bottom edge of the cover upwards until it rests in the open position.
- Closing: Push the cover downwards until it clicks securely into its closed position over the keypad.
5. Maintenance
Regular maintenance will extend the life of your replacement keypad cover.
- Cleaning: Clean the cover periodically with a soft, damp cloth and mild soap. Avoid abrasive cleaners or solvents, as these can damage the plastic finish.
- Inspection: Routinely inspect the cover for any signs of damage, cracks, or wear. Ensure the hinge mechanism is still functioning smoothly.
6. Troubleshooting
6.1 Cover Does Not Close Properly
- Check Hinge Alignment: Ensure the cover's hinge pins are fully seated in the keypad base.
