When your garage door keeps going back up after it begins to close, what are you going to do? It can be difficult to determine what exactly the issue is. By the end of this article, you should be able to troubleshoot this the next time that it happens! At the very least, you will have an idea of the common reasons this issue crops up.
Logic Board Replacement
The garage door is equipped with a logic board that serves as the brain of the garage door opener. This tends to wear out after a certain amount of time. An outdated logic board might create problems like repeatedly opening. This might mean that it is time for a replacement!
Limit Switch Adjustment
All garage door openers come with a limit switch to control the point of stoppage when the door is raised or lowered. If the garage door refuses to totally close and returns back up, it will be wise to look at the settings of the limit switch. A flathead screwdriver will help you adjust it.
Travel Down Setting Adjustment
This setting is responsible for controlling the distance to be traveled by the garage door before it closes all the way. Should it close before meeting the set distance, it might have gone up to prevent perceived damage after detecting something.
This could be a false alarm since garage door components can contract and actually change, causing the distance setting to change slightly as well. You might be able to resolve it by setting a new distance.
Inspection of Possible Blockage
You might want to look at the threshold to see if there is anything that might be blocking it. The garage door might sense even the tiniest blockage, which can be the direct cause of the problem at hand.
If there truly is nothing in the threshold, it might be another problem altogether. Go through the instruction manual of the garage door opener to understand the situation even better or get in touch with a professional who can help you.
