Start with one question: does the wall button work? If the wall button opens the door and the remote does not, the opener is fine and you have a remote problem – a battery, a lost pairing, or interference. If neither works, the problem is the opener, the power, or the door itself. That single test cuts the possibilities in half in five seconds.
If the wall button works but the remote does not
- Battery. Most remotes use a CR2032 or CR2016 coin cell. They fade rather than die, so the classic symptom is a remote that works from three feet but not from the driveway. Replace it first – it solves this more often than everything else combined.
- Reprogram the remote. Press and release the Learn button on the motor unit (usually under the light cover), then press the remote button within 30 seconds. Brands differ slightly; the label on the unit tells you the sequence.
- Range and interference. LED bulbs in the opener are a genuine and very common culprit – cheap LEDs emit radio noise on the same frequencies. If the range collapsed after you changed a bulb, that is your answer. Try a standard bulb or an LED rated as garage-door-opener safe.
- The antenna. A short wire hanging from the motor unit. If it has been tucked up, cut, or wrapped around the housing, range suffers.
- Keypad only. If an outside keypad has stopped working, its battery and its own pairing are separate from the remote.
If nothing works at all
- Power. Check the outlet with something else, and check the breaker. A GFCI outlet that tripped looks exactly like a dead opener.
- The lock button. Most wall consoles have a vacation lock that disables remotes. It gets pressed by accident constantly.
- Safety sensors. Look at the two units near the floor at either side. A steady light on both is healthy; a blinking or dark light means misaligned, dirty, or a wiring fault. A door with unhappy sensors will open but refuse to close.
- The trolley. If the motor runs and the rail moves but the door stays still, the trolley is disengaged – someone pulled the release cord. Re-engage it by pulling the cord toward the door or running the opener until it re-latches.
- The motor runs and nothing moves at all. Usually a stripped drive gear, a common and repairable failure. A hum with no movement often means a failed capacitor.
The check most people skip – and the one that matters most
Close the door, pull the release cord, and lift it by hand to waist height. If it is heavy, or will not stay where you put it, the opener is not your problem. It has been dragging a door that its springs stopped lifting, and replacing the motor without fixing the balance simply buys you a newer victim. The full mechanism is in how the wrong springs destroy garage door openers.
When it is time to replace rather than repair
Repair usually wins on openers under ten years old with available parts. Replacement starts making sense when the unit predates 2019 (California now requires battery backup on new residential openers – details here), when the logic board has failed, when parts are discontinued, or when it is the second repair in two years. If you are replacing anyway, it is the natural moment to consider a quieter belt drive or a ceiling-clearing wall-mount unit – here is how to choose. We quote both repair and replacement so the comparison is yours.
Frequently asked questions
Why does my remote work close up but not from the street?
A fading battery, LED bulb interference, or a damaged antenna wire – in that order of likelihood. Change the battery first, then try a non-LED bulb, then check that the antenna hangs free.
My door opens but will not close. What is wrong?
Almost always the safety sensors: dirty lenses, knocked out of alignment, or a wiring fault. Wipe both lenses with a dry cloth and check that the indicator lights are steady rather than blinking. If it still refuses, the close-limit setting or a binding track is next.
Can I reprogram the remote myself?
Yes – it is the one opener job that is genuinely homeowner-friendly. Find the Learn button on the motor unit, press and release it, then press your remote within about 30 seconds. Same process for a keypad, with the PIN entered afterwards.
