Garage door won't close unless I keep the button pushed in

13 posts in this topic

I have always owned older houses, so I don't know a #### thing about automatic garage doors. Add to that the fact that I was a philosophy major and then went to law school and thus have no practical skills, and I am at a loss here.

The garage door opens fine.

If I push the button to close it, the light flashes and it comes back up. To get it to close I have to hold the button in until it gets to the bottom.

Is this something I can fix without calling a garage door guy?

Have you two met?

I'm having a similar problem, only I don't think it's the sunlight as it's only recently starting happening:

The garage door will open fine, but won't close w/the remotes and will only close with the one mounted on the garage wall if I hold it down until the door has closed completely - otherwise it just clicks and the light on the garage door flickers. Is it possible the sensors (both located near the bottom of the garage door track) are out of sync (not pointing directly at each other)? If that's not the issue, what else could it be?

Oh yeah - sorry for the hijack.

Mine does the exact same thing....I am pretty sure its the sunlight hitting the sensors and the sensors thinking something is in the way.I am going to take the sensors off and see what happens.

There are two photo sensor near the ground at either side of your garage door. They are there to stop the garage door from closing if there is something in the path of the door. Likely one of the sensors got bumped or moved and it is not lining up correctly. Adjust the sensors until they line up and allow you to close the door by pressing the button on your remote once.

Your photoelectric eyes are probably out of alignment. On most, there is a green light (LED) on each unit that should be lit steadily. If your's is flickering, then you need to adjust it so that it remains steadily lit. If you accidentally bumped them they may not be directly facing eachother. That should do the trick.

Same as the other guy. Goalpost Relocation is the answer here.

This is probably it, but you may also have a substance on one of the sensors, so i would be sure to wipe them down too while you are at it.

So I checked my garage sensors and neither of the LED's are lit. I assume I have a short somewhere? Is there an easy way to find it?

Put your tongue on any exposed wire to see if it is getting current. If you don't feel a tingly sensation on your tongue with one of the exposed wires you have found your problem.

No. I have had similar issues with my sensors. For me, the low voltage wiring between the sensors and to the unit have become so brittle, I cannot cut them back and use them any more. As a temp "fix" I pulled both sensors and duct-tapped them face to face and wired them (with some wire I had left over from a ceiling fan install a few weekends ago) as if they were in place from the receiver to the sender and up to the opener. I am not recommending this due to the obvious dangers of not having them in proper place. I am going to get some LV wiring and rewire the whole thing as soon as I can (and warned the entire family to be VERY careful around the door until I can get the sensors back in place).

If you take the sensors off it wont help. They are fail safe, which means that when a photo eye has a fault or fails than the garage will not open until you get them fixed. They have to do it this way otherwise you wouldn't be aware that you have a faulty sensor that may not prevent the garage from coming down on a child.

You can probably bypass the sensor at the PCB where the terminals come in. It is probably a normally closed circuit that faults when the circuit opens up (someone standing between the sensors). If you short the two inputs at the PCB it will think that the circuit is closed and everything is OK. I wouldn't recommend this for a long term solution though, because you really should have the photo eyes fixed.

This didn't work for me when I tried it. Seemed like an easy fix to just complete the circuit, but no dice. This is why I had to rig the sensors together.
