Garage door openers are reliable for years, then start acting up in small ways. Knowing the difference between a remote problem, a sensor problem, and a real motor failure saves {state} homeowners time and money.

If the door stops short or reverses with the sensors clear, the travel or force limits have drifted. These adjustments need a careful hand — too much force defeats a safety feature, too little and the door won't close — so this is a good point to call a pro.
If your opener is over 15 years old, lacks rolling-code security, or has a failing board, a new belt-drive unit is usually the smart money — quieter, more secure, with Wi-Fi control and battery backup. If it's newer and the fix is a gear or sensor, repair it.
Does the motor run but the door not move? Does nothing happen on the remote but the wall button works? Does the door start down then reverse? Each symptom points to a different fix, so note exactly what happens before troubleshooting.
If you hear the motor but the door doesn't move, the trolley may be in manual-release mode (re-engage the red cord) or the drive gear has stripped — common on older chain openers and a quick fix. If the door feels heavy by hand, the real problem is a spring, not the opener.
If the door won't close or closes then reverses, it's almost always the sensors near the floor. Wipe the lenses, clear the path, and make sure both LEDs glow steady rather than blink. Federal law has required these since 1993, and a blocked beam stops the door by design.
Why does my garage door opener work intermittently?
Intermittent operation usually points to a dying remote battery, interference, or sensors that are slightly out of alignment. If those check out, the opener's logic board may be failing.
Are smart Wi-Fi openers worth it?
For most homeowners, yes — you get phone control, alerts if the door is left open, battery backup for outages, and modern rolling-code security. Belt-drive models are also far quieter than old chain drives.
