Replacing a garage door opener is a common issue, and programming a remote control is easy. Please look at one of the scenarios below for the best solution to your situation:
If your remote control has been lost or stolen, a person will have unabated access to your garage. You should erase all existing remote controls out of your receiver. See section below for LiftMaster. See your owner’s manual for other brands.
The overall length of a garage door opener is your door height plus three feet and requires a minimum of 2 1/2″ above the highest point of door travel. A LiftMaster residential jack shaft operator does not require any back room and can be installed with only 12″ of side room.
YES, they MUST be installed. The operator will not attempt to close the door if the beams are not installed. Due to federal regulations under UL325, there is no way to bypass or eliminate them. All residential garage door openers manufactured after 1993 are required to meet UL325.
If you purchased a battery backup unit, your opener will function normally even in a power outage.
If not, then:
How can I disconnect the garage door opener so I can manually open or close my garage door?
Pulling the emergency release handle disconnects the garage door from the garage door opener. This action allows you to open and close the door manually. The emergency release handle is located at the end of a red rope that hangs from the garage door opener rail near the top of the garage door.
Note: If you are using a residential jackshaft opener, the emergency release handle will be located at the bottom of the motor unit.
WARNING: To prevent possible SERIOUS INJURY or DEATH from a falling garage door:
- If possible, use emergency release handle to disengage trolley ONLY when garage door is CLOSED. Weak or broken springs or unbalanced door could result in an open door falling rapidly and/or unexpectedly.
- NEVER use emergency release handle unless garage doorway is clear of persons or obstructions.
- NEVER use handle to pull door open or closed. If rope knot becomes untied, you could fall.
For an opener with a square rail: Pull down on the emergency release handle so that the trolley release arm snaps into the vertical position. This locks out the trolley so the door can be raised and lowered manually as often as necessary.
For openers with a T-rail: Pull the red rope straight down. If you want to lock out the trolley, you need to pull the rope straight down and then pull it back towards the opener. This will allow you to raise and lower the door manually as often as necessary.
For the residential jackshaft opener: Disengage the door lock, door should be fully closed. Pull down on the emergency release handle until you hear a click and lift the door manually.
For an opener with a square rail: Pull the emergency release handle back toward the opener at an angle so that the trolley release arm is horizontal. The trolley will reconnect with the next operation, either manually or by activating the door.
For openers with a T-rail: Pull the handle straight down. The trolley will reconnect the next time the door is activated.
For the residential jackshaft opener: Pull the emergency release handle straight down a second time until you hear a click. The door will reconnect on the next up or down operation.
No. Remotes are brand specific, so you will need new remotes with your new system. If you need assistance, please contact us.
Your keyless entry can be programmed to activate many devices, including garage door openers and commercial door openers.
NOTE: This method requires two people if the Keyless Entry is already mounted outside the garage.
Change an Existing, Known PIN
If the existing PIN is known, it may be changed by one person without using a ladder.
Set a Temporary PIN
You may authorize access by visitors or service people with a temporary 4-digit PIN. After a programmed number of hours or number of accesses, this temporary PIN expires and will no longer open the door. It can be used to close the door even after it has expired.
Setting up the One Button Close feature
The opener can be closed by pressing only the ENTER button if the one button close feature has been activated. This feature has been activated at the factory.
To activate or deactivate this feature, press and hold buttons 1 and 9 for 10 seconds.
To program using the learn button
The garage door opener is equipped with two safety features that may prevent the door from closing and cause the lights to flash.
The Lock Button on the Door Control
The lock button on the door control may be activated. Press the button to turn this feature off. The light bulb will blink two times. This feature is designed to prompt you that the lock button is activated. When the lock button is ON the garage door opener will work from the door control but the remote controls are locked out.
The Safety Reversing Sensors
The most common reason for the lights to flash on the garage door opener and the door not closing is that the safety reversing sensors are misaligned or obstructed; this is a safety feature of the garage door opener.
When properly connected and aligned, the sensor will detect an obstacle in the path of its electronic beam. If an obstruction breaks the light beam while the door is closing, the door will stop and reverse to full open position, and the opener lights will flash 10 times.
Your garage door opener is equipped with a Self Diagnostic feature to help you determine what the issue is. Based on the model of your garage door opener, your garage door opener will flash an LED next to your learn button or flash the Up and Down arrows a number of times to indicate the issue. Use the table below to diagnose and resolve the issue.
LED | UP and DownArrow | Symptom | Answer |
1 | 1 Up 1 Down | Wires are cut, or not connected | How do I test or troubleshoot the safety sensor wires? |
2 | 1 Up 2 Down | Wires are reversed, or there is a short in the wiring | How do I test or troubleshoot the safety sensor wires? |
4 | 1 Up 4 Down | Safety Sensors are misaligned, or were momentarily obstructed | How do I align my safety reversing sensors? |
NOTE: The garage door can be closed by pressing and holding the door control push bar until down travel is completed.
The safety reversing sensors must be connected and aligned correctly before the garage door opener will move in the down direction. Typically issues with the safety sensor wiring occur because of a poor connection, incorrectly connected wires or a short in the wire from a staple.
NOTE: If you are unable to get the door closed and the safety sensors are the issue, the garage door can be closed by pressing and holding the Door Control push bar until down travel is completed.
If both safety sensor LED lights are not lit
Security+ 2.0 garage door openers have an energy conservation feature. If the garage door opener is Security+ 2.0, activate the door to determine if the opener was only in sleep mode.
Inspect the wiring
NOTE: The amber LED on the sending sensor will glow regardless of alignment or obstruction. If the green LED on the receiving sensor is off, dim or flickering (and the invisible light beam path is not obstructed), alignment is required. See How do I align my safety reversing sensors?
Test the safety sensor wires
Note: If after replacing the sensors, the LED’s still do not light, replace the logic board.
The LEDs on both the sending and receiving sensors will glow steadily when the wiring connections and alignment are correct. The amber LED on the sending sensor will glow regardless of alignment or obstruction. If the green LED on the receiving sensor is off, dim, or flickering (and the invisible light beam path is not obstructed), alignment is required.
Note: On the older safety sensors, both LED lights are green. The receiving sensor is the one where the green light goes out when you pass your hand in front of the sensor. The sending sensor stays solid.
NOTE: If you are unable to get the door closed and the safety sensors are the issue, the garage door can be closed by pressing and holding the door control push bar until down travel is completed.
Find your garage door opener’s Learn Button to determine what model of remote control is compatible. The Learn Button is located on either the back or the right side of the opener, near the hanging antenna wire.

There are a few instances that the memory of your opener would need to be erased.
NOTE: Erasing the memory will remove ALL remote controls and keyless entry codes from the garage door opener.
Begin by locating the LEARN button on the back or side of the motor unit; generally this is on the same side as the antenna wire. You may need to remove a light lens cover or open a control panel to gain access. The LEARN button may be green, orange, red, purple or yellow, and will have a small LED next to it.
Note: Erasing the memory on your opener will clear out any working remotes or keyless entries. You will need to reprogram them.

Premium LiftMaster garage door openers featuring a battery backup and/or Wi-Fi connectivity have a buzzer to alert you by making a beeping sound. You will hear a beep to confirm a step is performed successfully or you will hear a beep to diagnose an issue. The number of beeps heard will depend on the type of garage door opener and the function you are performing on the garage door opener.
If you have a garage door opener with a battery backup and it is…
Note: To temporarily stop the beeping while waiting on a new battery, unplug the unit and disconnect the battery. After disconnecting the battery, plug the unit back and the beeping will stop.
Useful information about the backup battery
The battery is designed to run 20 full cycles on a full charge, which equates to about 1 -2 days of normal operation. If the power is not restored by this time, the battery needs to be unplugged from the motor. If you do not disconnect the battery, it will drain too low and will not recharge. The battery would then need to be replaced.
If your garage door opener has Sec+2.0
