Why Does My Garage Door Go Up But Not Down?
Don’t leave your door hanging
Never operate a broken garage door, as it could lead to severe injury.
Misaligned sensors, malfunctioning openers, or mechanical damage can all make a garage door go up but not down
Garage door repair costs $263 on average. Garage door replacement can cost from $750 to $6,325.
Imagine opening your garage door for spring cleaning, only to find out it won’t come back down after you’ve spent hours rearranging and decluttering. Having a faulty garage door can be frustrating, but here are some handy tips to help you diagnose, troubleshoot, and find a solution ASAP.
Replacing garage doors and garage door springs can be dangerous. Garage doors are very heavy and the springs are under a lot of tension. A garage door pro has the tools and experience to do this project safely.
1. Misaligned Sensors
Misaligned sensors are one of the most common reasons why your garage doors are stuck at the top. Most garage door openers rely on sensors, also known as the safety beam, to ensure the doors don’t drop if something is under them. This prevents the doors from closing when an object or a person is passing through, even if you press the down button on the opener.
If the light on one of the sensors is out, your sensors are misaligned. This prevents the door from going back down because the system reads the signals as if something is under the door, thus keeping the doors up as a safety response.
Re-aligning the Sensors
Realigning your garage door sensors can be easily done by yourself. Simply adjust the sensor with the light off by moving it left and right or forth and backward. Once the sensors realign, the light should come back on. Test and see if your garage door now closes normally. If you believe the sensors themselves are faulty, simply replace them. You can find a two-pack universal sensor for replacement at hardware stores for less than $40.
2. Faulty Wiring
Wiring issues can stop your garage door from closing. Critters, aging and deterioration, or impact damage caused by sharp objects can all damage the wires. To inspect yourself, follow the wiring from the garage door opener to the sensors and look for visible damages. Look for signs of corrosion, physical damage, or potential short circuits.
Repair Faulty Garage Door Wiring
We recommend you hire a garage door repair technician if you suspect there are wiring issues. An electrician may also be able to look into the problem for you. Garage door repair costs between $155 and $377 per repair, and the average sits around $263.
3. Disrupted Opener Frequency
Garage door radio frequency problems are another reason why your door won’t come back down. The remote communicates with the garage door opening using radio frequency. If something is jamming the signal and causes your remote to lose contact with the opener, the door will stay where it is, whether open or closed.
Troubleshooting Signal Interference
Make sure your system is updated to the latest version. Then, try resetting your opener code using the “learn” button on your remote. If neither of those methods works, you need to identify the source of interference. Turn off the devices with a radio transmitter, then turn them on one by one, testing the remote after each until you find the appliance that’s affecting the signal.
4. Damaged Bearing or Tracks
Mechanical failure, such as worn-out bearings or bent tracks, is the most severe reason that may cause your garage door to only go up. In this case, your garage door is physically stuck on top of the track, and forcing it to come down can be dangerous. Mechanical issues often have warning signs. If you notice your door making strange noises going up, or the movement seems less smooth than usual, it’s best to schedule an inspection before the problems become worse.
Garage Door Maintenance
Regular maintenance is key to preventing mechanical issues. Use silicon lube or lubricant specifically made for garage doors on the roller wheel bearings, the bearing shafts, and the hinges. However, avoid dripping any lubricant on the working parts of the track, as it will attract dirt and grime and cause the garage door to slide. You should also check the fastening on the roller and counterweight cables. Regular inspections with manual openings are conducted to ensure the parts are working properly.
Repairing Damaged Doors
If you believe mechanical issues are causing your doors to get stuck on top of the tracks, do not attempt to fix things yourself. Garage doors carry a significant level of preload tension between the door and the counterweight. Forcefully trying to lower a stuck door or loosening the door from the track while the opener is engaged can lead to severe and sometimes fatal injuries.
If you want to lower the door, disconnect the power and try to close it manually. If that doesn’t work, contact a professional to repair or replace the door. Garage door replacement can range from $750 to $6,325 and costs $2,743 in most cases.
