Garage Door Motor Troubles? Easy Fixes to Save Time & Money

If you’ve ever been stuck inside (or outside) your garage because your garage door motor stopped working, you know how frustrating it can be. The garage door motor is the heart of your automatic door system — when it fails, your whole routine is disrupted.
This guide will help you understand how your garage door motor works, the common problems that can arise, easy troubleshooting steps, and when it’s best to call in the pros. By the end, you’ll know exactly how to handle motor issues before they cost you big money.
Understanding Your Garage Door Motor
What Does a Garage Door Motor Do?
Your garage door motor is the main power source that moves your garage door up and down. It converts electrical energy into mechanical motion, pulling or pushing the door through a chain, belt, or screw drive system. Without it, your garage door would be manual — heavy, slow, and inconvenient.
Common Types of Garage Door Motors
There are three primary types of garage door motors:
- Chain-Drive Motors – Affordable and durable but noisier.
- Belt-Drive Motors – Quiet and smooth but slightly pricier.
- Screw-Drive Motors – Fewer moving parts and low maintenance but not as quiet.
Each type has its pros and cons, so knowing which one you own can help when troubleshooting.
Signs Your Garage Door Motor Might Be Failing
Watch for:
- Strange grinding or clicking noises
- Door moving slower than usual
- Motor running but no movement
- Intermittent operation or failure to start
Common Garage Door Motor Problems
Motor Makes Noise But Door Doesn’t Move
This often means the drive gear is worn out or a part of the lifting mechanism is disconnected.
Door Opens Slowly or Stops Midway
Possible causes include misaligned tracks, weak motor performance, or obstructions.
Motor Runs But Lights Flicker
This may be a sign of an electrical issue or power fluctuation.
Motor Doesn’t Respond at All
If pressing the remote or wall button does nothing, it could be a dead motor, tripped breaker, or faulty wiring.

How to Troubleshoot Garage Door Motor Issues
Step 1: Check the Power Supply
- Ensure the motor is plugged in
- Check the breaker box
- Test the outlet with another device
Step 2: Inspect the Remote and Wall Switch
Replace remote batteries, clean the contacts, and check wiring to the wall switch.
Step 3: Examine the Safety Sensors
Dirty or misaligned safety sensors can prevent operation. Clean them and realign if needed.
Step 4: Test the Motor Gears
Open the motor housing and check for broken or stripped gears. If damaged, they need replacing.
DIY Garage Door Motor Repairs You Can Try
