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:

1. Chain-Drive Motors – Affordable and durable but noisier.
2. Belt-Drive Motors – Quiet and smooth but slightly pricier.
3. 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.
