Symptoms
- Light doesn't turn on when the door operates or the button is pressed
- Motor and door operate normally otherwise
- Light worked before but stopped recently
Likely causes
- CommonBurned-out bulbBulbs eventually burn out just like any household light.
- CommonWrong bulb type causing early failureStandard bulbs can fail quickly from the vibration of opener operation; vibration-resistant or LED bulbs made for openers last longer.
- PossibleBulb not screwed in fullyVibration over time can loosen a bulb enough to lose contact.
- PossibleLight setting turned off in settings or via a wall controlSome openers or connected wall controls have a light on/off setting separate from bulb function.
- Less commonFailed light socket or wiringAfter ruling out the bulb, a socket or wiring fault is possible.
What to do
- Check that the bulb is screwed in fully and try tightening it slightly.
- Replace the bulb with a new one, ideally a vibration-resistant or LED bulb rated for garage door openers.
- Check any wall control or app settings for a light on/off toggle that may have been changed.
- Confirm the opener's light setting (some models let you set the light to turn off automatically after a certain time).
- If a new bulb still doesn't light up, check the socket for obvious damage or corrosion.
- If the socket appears fine but the light still won't work, the opener's internal wiring to the light may need professional inspection.
