Garage Door Motor Not Working? Troubleshooting & Repair Guide
The motor is the heart of your garage door opener. When it fails, your door becomes a very heavy manual object. Before calling for repair, there are a few things you can check yourself — and some clear signs that it’s time for professional help.
Motor Runs But Door Doesn’t Move
If you hear the motor humming or running but the door stays put, the internal gears have likely stripped. This is the most common motor failure, especially on chain-drive openers over 8-10 years old. The plastic or nylon gears inside the motor unit wear down over time until they can no longer engage. Gear replacement is possible on many models, but if the opener is old, replacing the entire unit is often more cost-effective.
Motor Makes a Clicking Sound But Won’t Run
A clicking sound usually indicates a capacitor issue. The capacitor gives the motor the initial boost it needs to start spinning. When it fails, you hear the relay clicking but the motor can’t start. Capacitor replacement is a quick, affordable repair on most opener models.
Motor Is Completely Dead — No Sound at All
Check the obvious first. Is the opener plugged in? Is the outlet working (test with another device)? Is the circuit breaker tripped? Check the GFCI outlet if your garage has one — press the reset button. If power is confirmed and the motor still won’t respond, the motor itself, the circuit board, or the transformer may have failed.
Motor Starts Then Stops
If the motor runs for a second then shuts off, the force settings may need adjustment, or the door could be binding due to a track or spring issue. The opener has a built-in safety feature that stops the motor if it detects too much resistance. Check if the door moves freely by disconnecting the opener (pull the red emergency release cord) and lifting the door manually. If it’s heavy or sticks, the problem is the door — not the motor.
Motor Runs in One Direction Only
If the door opens but won’t close (or vice versa), check the safety sensors first. Misaligned or blocked sensors will prevent the door from closing. If the sensors are fine, the limit switches inside the opener may need adjustment. These switches tell the motor how far to travel in each direction.
When to Repair vs. Replace the Motor
Repair makes sense when the opener is less than 10 years old and the fix is a gear, capacitor, or circuit board replacement. Replace the entire opener when the motor is 12+ years old, when repair costs exceed 50% of a new unit, or when you want modern features like Wi-Fi, battery backup, or quiet belt-drive operation.
A new garage door opener installed typically costs $300-$600 depending on the model and drive type. Belt-drive openers from LiftMaster or Chamberlain are our most popular recommendation for homeowners who want quiet, reliable operation.
