Garage door opener repair can be quite complicated, depending on the nature of the problem. Due to the presence of electronics and various moving parts, there are quite a few things that can go wrong. If the garage door will not open, then you will need to determine what is wrong with the door before you can fix it. You should also consult the manuals that came with the motor and the garage door to see if there are any helpful troubleshooting tips specific to your installation. The following considers some common problems with garage doors and how they can be fixed.
If the Door Doesn’t Close
If the door will not close at all, then are a few things that could be wrong with it. Garage doors have a safety sensor which will stop them from closing if there is something or someone in the way. This is one of the most common problems. The first thing to do would be to check if there is anything in the way, but it is more likely that the opener sensor is not aligned correctly. Use a ladder to reach the sensor and make sure that it is pointed directly downwards, pointing at the ground directly beneath the door.
If the Door Does Not Close Completely
This is most commonly a technical problem which probably involves the chain driver of the system. This can happen if the chain is too tight and not allowing the door to go down completely. To repair this, you will need to detach the garage door opener from the main power and remove the control box. Open the control box to find the chain. Move the chain in or out of the box by turning the bolt of the chain driver with an adjustable wrench. There is an element of trial and error to this, so you may need to test the door a few times until it works properly.
If the Garage Door Shuts but then Goes Back Up
The safety reverse feature could be causing this. If there is a problem with the balance of the door, then you will need to fix this before the door will work correctly again. This requires adjusting the limits of the door. When the garage door closes, it should not necessarily be touching firmly against the ground, as this will cause it to go back up again. Refer to the manual of your garage door to determine how to adjust the force and travel limits.
If the Door Does Not Respond at All
This could either be a problem with the motor, the remote control or the sensor. To check if there is anything wrong with the opener sensor, run the LED diagnostics as directed to by the instruction manual for your device. You may also want to try changing the batteries. If you have tried these things and the garage door still doesn’t work, then you may need to replace the opening system entirely.
