Garage Door Goes Up But Not Down

Garage doors are essential for home security and convenience, but they can be frustrating when they malfunction. One common issue is when the garage door goes up but not down. This problem can be caused by several factors, including mechanical issues, electrical problems, or sensor misalignment.

Mechanical Issues

The most common mechanical issue that prevents a garage door from going down is a broken spring. Garage door springs are essential for counterbalancing the weight of the door, and if they break, the door will be too heavy to open or close. Other mechanical issues that can cause the door to go up but not down include:

Bent or damaged tracks
Loose or broken rollers
Misaligned gears
Faulty opener motor

Electrical Problems

Electrical problems can also prevent a garage door from going down. These problems can include:

Faulty wiring
Blown fuses
Tripped circuit breakers
Malfunctioning sensors

Sensor Misalignment

Garage door sensors are essential for safety, as they prevent the door from closing if something is in the way. If the sensors are misaligned, the door may not close properly.

Troubleshooting

If your garage door goes up but not down, there are a few things you can do to troubleshoot the problem:

Check the springs: Look for broken or damaged springs and replace them if necessary.
Inspect the tracks: Make sure the tracks are straight and undamaged and that the rollers are moving smoothly.
Test the opener motor: Disconnect the opener from the power supply and try to open and close the door manually. If the door opens and closes easily, the opener motor is likely faulty.
Check the wiring: Look for any loose or damaged wires and repair or replace them as necessary.
Test the sensors: Place an object in the path of the sensors and see if the door stops closing. If the door does not stop, the sensors may need to be adjusted.

If you are unable to troubleshoot the problem yourself, it is best to contact a qualified garage door repair technician for assistance.
