You pull into your driveway after a long day of work. You can't wait to unwind with a glass of wine and a good show. You press the button for your gate opener, but nothing happens. What do you do? Here are five tips for troubleshooting your Liftmaster dual swing gate opener:
1. Check the battery.
The gate opener uses a battery when it's not getting electrical power. If the battery runs out of charge or if the battery is too old, the gate opener will stop working. Check the condition of the battery for signs of corrosion or acid leaks. If the battery looks good, a simple charge can get your gate opener working again. If the battery is damaged or old, replace it. Check the batteries in your remote too.
2. Check the power source.
Your gate opener needs a constant supply of power to operate. Is the gate opener plugged in? If it's plugged in but still not working, try plugging it into a different outlet. If this doesn't work try resetting the circuit breaker. Also, check your fuse boxes for blown fuses.
3. Check for obstructions.
Liftmaster gate openers have very sensitive obstruction detection systems. This is for safety purposes to keep gates from closing on children, pets, or cars. Check the entire area for anything that could trigger the obstruction sensors and move the object out of the way. Press the reset button on the control panel and hold it for thirty seconds. Even if there was no obstruction, reset the gates anyway since an animal could have triggered it.
4. Reprogram the remote.
The gate opener's remote can become faulty and need to be reset. In order to reset the remote, you need to reprogram it. Here are the steps to reprogram your remote:
- Locate the logic board. It will have a blinking light on it. Once you've found the board, look for the "learn" button.
- Push the button for a few seconds.
- On the remote, press and hold down the button for three seconds. Check the light on the logic board to make sure it's blinking. This means that your remote is reprogrammed.
5. Check the signal.
In order to respond to the remote, the gate opener's receiver needs an adequate radio signal. If anything interferes with the signal, the opener won't respond. Check the antenna for your gate opener. Clean it if there is any dirt or grime and check it for signs of damage. If the antenna appears fine, put it as high as it can go to get a better signal. If your opener still doesn't work, it will need a signal amplifier.
