Frequently Asked Questions - 050ACTWFLK LIFT-MASTER

How to program a remote control on the Lift-Master 050ACTWFLK garage door opener?

Press and release the Learn button on the opener. The indicator light turns on for 30 seconds. Within this time, press and release the remote control button. Release when the opener light flashes or two clicks are heard.

How to adjust the travel limits of the door?

Hold down the adjustment button until the UP button flashes. Use the UP and DOWN buttons to move the door to the desired position. Press the adjustment button to confirm each position. The lights flash twice at each step. If the lights flash 5 times, the time has expired; if they flash 10 times, the sensors are misaligned.

How to test the safety reverse system?

Place a 1.5-inch (3.8 cm) thick board centered under the open door. Close the door with the remote. The door MUST reverse upon contact with the board. If it stops without reversing, increase the close travel limit and repeat the test. Perform this test monthly.

How to change the receiver logic board?

Disconnect the AC power and battery. Remove the lens, disconnect wires and harnesses, remove screws and fasteners to remove the old board. Install the new board by connecting the harnesses (tabs toward the end panel), insert the antenna wires, secure with screws, reconnect the wires (white to white, white/red to red, etc.) and replace the lens.

What to do if the lights flash 10 times during travel adjustment?

This indicates that the safety reversing sensors are misaligned or obstructed. Align the sensors (the LEDs must be on) and clear any obstruction. Then perform a full open/close cycle with the remote or the UP/DOWN buttons. If the door does not move, repeat the travel programming.

Can I use the opener without the backup battery?

Yes, the opener operates on AC power. The backup battery serves in case of power outage. If the battery is discharged, the opener will operate normally as long as AC power is present. For optimal use, keep the battery charged.

How to connect the opener to Wi-Fi and the myQ app?

After installing the new logic board, use the provided myQ serial number to add the opener to your myQ account. Follow the instructions in the myQ manual to program the Wi-Fi signal. The Learn button also allows you to configure the connection.

Why does the door control not sync with the opener?

Press the push bar of the door control until the opener activates (this may take up to 3 presses). Then, each press should activate the opener. If the problem persists, check the connections or replace the battery in the door control.

What are the dangers associated with improper installation of the reverse system?

Without a functioning reverse system, the door may not reverse upon encountering an obstacle, risking serious injury or death to people, especially children. It is essential to test the system monthly and verify that the door reverses upon contact with a 1.5-inch high object.

Where to find the replacement receiver logic board?

The replacement receiver logic board is referenced under part number 041DG210-1. You can order it from your authorized dealer or from Lift-Master customer service. Make sure to use the provided label to maintain the warranty.
