Garage Door Opener Won't Open the Door
Most 'broken' garage door openers are actually working fine — the issue is a misaligned safety eye, a tripped lock button, or a worn-out remote battery. Walk this checklist before assuming you need a $400 service call.

Steps
-
1
Check the wall switch for a lock light
Most wall consoles have a "lock" or "vacation" button that disables remotes. If the lock light is on, hold it for a few seconds to disable.
-
2
Check the safety eyes
At the bottom of each side rail, two small sensors face each other. Both should show steady (not blinking) LEDs. If one is blinking, gently realign — they need to point exactly at each other. Wipe lenses clean with a soft cloth.
Tip: A spider web across one sensor is a real cause. Look closely. -
3
Try the wall button
If the wall button works but the remote doesn't, the issue is the remote — replace the battery, reprogram if needed (most remotes have a learn button on the motor unit; press, then press the remote within 30 seconds).

4
Listen for the motor
Press the button. If the motor hums but the door doesn't move, the trolley (the carriage on the rail) may be disengaged from the emergency release. Pull the red emergency cord backward toward the motor until it clicks back in.

5
Check for a tripped breaker
No motor sound at all — check the breaker for the garage circuit and confirm the opener is plugged in. GFCI outlets can also trip.

6
Lubricate moving parts
Apply garage door lubricant to the chain or screw drive, the rollers, and the hinges. Don't lubricate the rails themselves.

When to call a pro
Broken torsion springs above the door (loud bang followed by a door that won't lift) — DO NOT attempt to fix yourself. The springs store enough energy to maim. Same for snapped cables. Pro service call.
