Check the Photo Eyes First

One of the most common electrical issues that causes a garage door to open but not close is a problem with the photo eyes. These are the square boxes located near the bottom of the door frame, on either side. They work together to create an invisible light beam that runs across the opening. If anything breaks the beam while the door is closing, it will stop and reverse direction.

Over time, the photo eyes can become dusty or misaligned. First, clean them gently with a microfiber cloth. Then check that they are pointing directly at each other from their mounting positions. Even being a small fraction of an inch off can cause issues. If cleaning and adjusting doesn’t help, the photo eyes may need to be replaced. New replacements are inexpensive, usually under $25 for a set.

Test the Force Settings

Older garage door openers may have force settings that are too low to push the door down fully into the closed position. On the back or underside of the unit, there are usually numbered dials or slider controls for adjusting the force levels. Start by increasing the downforce setting a notch at a time and testing until the door closes fully under power. Be careful not to crank the force too high which could damage the door or opener.

Replace Batteries as Needed

If the door works on battery power but not wall power, it’s a sign the batteries are getting low. Always keep a set of high-quality alkaline batteries on hand as a backup. But rechargeable lithium batteries will last much longer between charges if that’s an option for your specific model. Either way, fresh batteries can sometimes cure an opener that only works intermittently.

Check All Connections

Loose or corroded wires are another frequent electrical culprit. Examine the wire connections inside the opener housing as well as at the wall control station. Use a wire brush or spray contact cleaner to remove any green buildup. Then tighten any loose screws securely. Check for worn or damaged wires as well that may need replacing. A simple connection issue could be causing dropped signals.

With a little time and some basic troubleshooting, many garage door electrical problems can be fixed without a service call. Always be careful working with electric garage door opener parts. Try the tips above starting with the easiest tests first before moving on to more complex repairs or replacements if needed. With some patience and a process of elimination, you’ll have that door opening and closing like normal again in no time.
