Watch our Expert Gate Technician Replace a Swing Gate Opener

The experts at Orange County Garage and Gates are dedicated to demystifying electric gates, so our customers can maintain a better understanding of this essential equipment that keeps their homes, businesses, and property safe and contained. In the attached video, our experts demonstrate the process of installing a Liftmaster LA400PKGU 24VDC model on a 14 foot swing gate.

Removing the Malfunctioning Gate Opener Arm and Rewiring Circuitry

First, we have to remove a malfunctioning AFC Hydraulic arm due to it’s damaged chamber and oil leakage. We use tools to remove the old arm and unplug all the electrical wires that attach to the metal equipment, taking care not to tear them from the board mainframe. We quickly ran into an issue – the gate’s 220 voltage did not meet our need for a 110 voltage, so we ran new 110 wire voltages into a brand new control board with which we replaced the older one with the incorrect voltage.


Welding the new Arm and Programming the Photo Eye

Then, we welded the brand new arm to the gate, attaching it with great care by attaching ridid brackets to the stability bar. Then, we install the safety photo eye that helps stop and reverse the gate if somebody, or something finds themselves in the way of the gate’s motion. As our repairman explains, today, no proper gates can be installed without an electric photo eye.


Now, it’s time to test the opener, and make the proper adjustments to the control boards setting levels. We’re happy with the door’s operation, as it’s perfectly smooth and quiet, as opposed to the janky way the last door operated and leaked oil.


Programming the Remote, and Installing the new Wireless Keypad

Then, we need to program the portable LiftMaster remote for ease of use. We find the right matching frequency, pressing the button to recalibrate while activating the gate so the remote can set on the correct signal. It matches, opening the gate with nothing but a slight whisper of noise. Opening and closing tests both work perfectly, to our non-surprised satisfaction. The very same remote is programmed to use the garage door in the back.


Then, we move on to remove the garage keypad for the old opener, and replace it with a brand new keypad matching the brand new opener. We need to drill new holes in the wall to fit the new wireless keypad’s attachment size, screwing and affixing it onto the wall. Then, we program the universal wireless keypad to join it with the control board. We enter some data into the keypad, walk back to the control board to verify, and then input the code in the new keypad to enter it into programming mode, and enter all the necessary instructions until we get a beep confirming our programming. After a successful test, we have verified that the new wireless keypad is programmed and works, the remote works, and our job has been successfully completed to our customer’s 100% satisfaction!
