What to Do in a Blackout
Blackouts in bad weather are frustrating, but common. While you’re waiting for the power to come back on, you might want to light candles and play card games … or you might want to leave your house and go somewhere where there’s light and entertainment.
Prevent This Problem from Recurring
When you have to revert to manually operating your garage door, you’ve gone back to the dark ages, both literally and figuratively. But you can make sure this doesn’t happen again in the event of another blackout.
Your Battery Backup Options
Garage door backup power batteries are built into your opening system. If you didn’t select this add-on option when purchasing your lift, you can’t add one after the fact.
Test Your Backup Power Source Regularly
Make sure the battery backup is fully charged, and test it every few months to make sure it’s in good working condition.
Why is my garage door sensor not working?
A common cause of a malfunctioning garage door sensor is lack of power supply. Look for small LED lights on the sensors. If they’re turned on in both the sensors, then there is no issue with the power supply. If you find the lights turned off in one or both the sensors, it indicates that there is a problem in power supply.
How to prevent garage door from closing?
1. Sensor path – Make sure nothing is obstructing the sensor beam. In general, garage door sensors block the door from closing if there is an object nearby. This precaution ensures that the door doesn’t close when your car is in the doorway. The same mechanism kicks in when other objects are placed near the door too.
Why are my door sensor lenses covered in dirt?

Is the Garage Door Sensor On or Connected?
This might sound like common sense but a simple disconnection could be the problem. Make sure to check if the sensors are on and if you’ve plugged in the power supply.
Make Sure Nothing Blocks the Sensors
Look at the lights and see if they blink. If they keep on blinking then it’s possible something is in the way. Even the smallest item can block the sensors’ capability to detect your car.
Tend to Broken Wiring
If everything seems fine but the doors still don’t function right then you might be dealing with faulty wiring. The sensor could be working as intended but if the wires to the motor unit break then the doors won’t function.
Look for Motor Unit Error Code
When in doubt, go back to the manual. The sensor lights will signal what kind of condition they are in. It’s not always accurate but it can give you an idea of what’s broken.
Seek Garage Door Sensor Repair Services
If cleaning or realigning your sensors don’t do the trick, it’s time to hire professional repair services.
How do garage door sensors work?
