Six Causes of an Opener That Fails Only Sometimes
These are the usual suspects.
Weak remote battery
A weak battery cuts range long before it stops the remote. It can make the remote work only on some days.
Signal interference
Radio interference can cut a remote’s range. Chamberlain points to LED light bulbs as one cause.
A photo eye slightly out of line
A bump or a loose bracket can leave a sensor almost aligned, so the beam breaks on some days.
A loose connection
A loose plug, wire, or connector can break contact when the door or the opener vibrates.
A failing circuit board
A board that is starting to fail can work some of the time. A storm surge can start the damage.
Heat stress
Electronics and batteries do worse in extreme heat. Something that works in the morning may fail in the afternoon.
What You Can Safely Do
No tools needed. The goal is to give us a clear pattern.

Safe steps
- Keep a short log. Write down what failed, the time, and the weather.
- Replace the remote battery. A weak battery is a common cause.
- Check the photo eyes. Wipe both lenses and check that both lights glow steady.
- Check the plug. Make sure it is fully seated, and test the outlet.
- Note anything new near the opener, such as light bulbs or devices.
Do not
Do not tape over or bypass a sensor to make the door work. Do not open the opener housing, because mains power runs inside. Do not touch springs or cables. DASMA says they are under extreme tension. If the safety reverse ever fails, stop using the opener.
Why Openers Fail on and off in Las Vegas
Heat
Las Vegas hit 120 degrees on July 7, 2024, according to the National Weather Service. Heat is hard on boards and batteries.
Storms and surges
Monsoon storms run from late June into September. A surge can start damage that shows up later as on and off failures.
Age and wear
Parts wear out unevenly. Many openers last 10 to 15 years, according to House Digest.

Intermittent Opener Questions in Las Vegas
Why does my garage door opener work only sometimes?
Common causes are a weak remote battery, radio interference, a photo eye that is slightly out of line, a loose connection, and a failing circuit board. The pattern of when it fails points to the cause, so write it down.
Why does my remote work only sometimes?
A weak battery and radio interference are the usual causes. Chamberlain says remotes that all stop together or work on and off may point to interference. See our remote guide.
Can LED light bulbs make my opener work only sometimes?
Yes. Some LED bulbs create radio interference that cuts a remote’s range, according to Chamberlain. If the trouble started after you changed bulbs near the opener, tell us.
Why does my door close some days and reverse on others?
A photo eye that is slightly out of line, a dirty lens, or bright sun on a sensor can interrupt the beam on some days. Wipe both lenses and check that both lights glow steady. See our reversing guide.
Can heat make an opener fail only in the afternoon?
It can. Heat is hard on electronics and batteries, and Las Vegas hit 120 degrees in 2024. A part that works in the morning may fail when it gets hot.
Can a storm cause an opener to fail on and off?
Yes. A surge can damage the circuit board so that it works some of the time. If the trouble started after a storm, tell us.
What should I write down before I call?
Note what the opener did, the time of day, the weather, and whether the wall button and the remote both failed. Also note anything new, such as light bulbs or devices near the opener.
Is an opener that works only sometimes unsafe?
It can be, if the safety reverse or the photo eyes fail on some days. Test the safety reverse each month, and call us if it ever fails. Our yearly checkup covers it.
How much does it cost to fix an on and off problem?
It depends on the cause. A battery or sensor fix usually costs less than a new board. You get the total before work starts. Our repair cost guide explains what changes the price.
Do you repair all opener brands?
We repair LiftMaster, Chamberlain, Genie, and Craftsman openers, and other supported brands.
