Garage Door Opener Keeps Clicking but Won't Run
When your opener clicks but the motor won't run, it usually means the motor is getting power but something is stopping it from moving the door safely. The most common causes are a tripped travel/force limit, a disengaged trolley (your door is in manual mode), or a worn-out main drive gear. Start by checking whether the door itself moves freely by hand, then look at the trolley and the opener's limit settings before assuming the worst.
Step by step
-
1
Pull the manual release and lift the door by hand
With the door fully closed, grab the red emergency release cord hanging from the trolley and pull it to disconnect the door from the opener. Now lift the door manually. If it's heavy, sticks, or slams back down, the problem is your springs or rollers, not the opener, and the opener is clicking because it's straining against a door it can't move. If the door glides smoothly and stays put halfway up, the opener is the culprit. Re-engage the trolley before testing the opener again (pull the cord toward the door or run the opener once).

Confirm the trolley is actually connected to the opener
A clicking opener with a motor that hums but no door movement often just means the trolley is disengaged, so the carriage is spinning free of the chain or belt. Look at the trolley along the rail. If the opener's carriage moves but the part connected to the door arm doesn't, pull the release cord back toward the motor and run the opener so it re-locks. You'll hear or see it snap back into the chain.

Listen for a humming motor, then check the main drive gear
If you hear the motor hum or click for a second or two and the trolley doesn't budge at all, the plastic main drive gear has likely stripped. This is the number-one failure on Chamberlain, LiftMaster, and Craftsman chain-drive units over 8 to 12 years old. You'll often find little white or gray plastic shavings on the garage floor under the motor head. A drive gear kit is inexpensive, but the repair is fiddly; many homeowners opt to have it done.

Reset the travel and force limits
If the door starts to move then reverses and clicks, the opener thinks it's hitting an obstruction. The travel limits (how far it goes) or force settings (how hard it pushes) may be off, especially after a power outage or recent adjustments. Find the up/down limit dials or buttons on the back of the motor unit and follow your model's manual to recalibrate. Make small quarter-turn adjustments and test between each one.

Check the safety sensors and for a stuck door
Look at the two small photo-eye sensors near the bottom of each track. If one light is off or blinking, they're misaligned or dirty. Wipe the lenses, nudge them until both glow steady, and tighten the brackets. Also scan the tracks for a bent section, a debris jam, or a roller that has popped out, any of which can stop the door and make the opener click in protest.

6
Cut power and reset the unit
Unplug the opener for 30 seconds or flip its breaker, then restore power. This clears the logic board, which can lock up after a surge or repeated obstruction errors. If it runs normally afterward, you've solved it. If it immediately clicks and stalls again, you've narrowed it down to a mechanical or motor issue from the steps above.
When to call a pro
Call a pro if the door is heavy or won't lift by hand (that's a broken or unbalanced spring under dangerous tension, never DIY it), if you found plastic gear shavings, or if the motor hums but nothing moves after you've checked the trolley and limits.

Why does my garage door opener click but the door doesn't move?
A click with no movement almost always means the motor has power but can't drive the door. The usual suspects are a disengaged trolley (door is in manual mode), a stripped plastic main drive gear, or a tripped force limit. Pull the manual release and lift the door by hand first; if it's hard to move, the issue is your springs, not the opener.
Is it safe to keep pressing the button if the opener just clicks?
No. Repeatedly triggering an opener that's straining against a stuck door or a stripped gear can overheat the motor, burn out the logic board, or worsen the mechanical damage. Press it once or twice to diagnose, then stop and work through the checks above or call a technician.
How much does it cost to fix an opener that clicks but won't run?
It depends on the cause. A drive gear replacement typically runs about $85 to $200 with labor, while limit or sensor recalibration is often a quick, low-cost service call. If the motor or logic board is fried on a 12-plus-year-old unit, a full opener replacement (commonly $350 to $700 installed) is usually the smarter money.
Can a power outage make my opener click and stall?
Yes. A surge or outage can scramble the opener's travel limits and lock up its logic board, so it clicks and either won't move or reverses partway. Unplug the unit for 30 seconds to reset it, then recalibrate the up/down limits per your manual. That clears the problem in many cases.
