Garage Door Opener Parts

Your garage door keeps working, day in and day out. What helps that big door function? The garage door opener! The average garage door opens and closes 1500 times each year and most tend to last at least 10,000 cycles. If your opener seems to be acting slow, here is a quick guide to help you know each part and piece that may need fixing or replacement. Below are some of the important parts that may need more frequent replacement.

Opener & components

  1. Motor and Gears. This is what gets the door moving; both opening and closing.
  2. T-rail/Driver Guide. This guides and protects the chain, screw, or belt as the door opens and closes.
  3. Height Adjustment. This controls the distance the door travels. Can also be adjusted to various levels of force that cause the door to stop, such as pushing upwards on it.
  4. Inverter and Battery. The inverter transfers AC power from the home to DC power necessary to operate the opener. The battery is for times when the power may be out.

Types of Drives:


 Chain drive

Typically the most cost effective option. Looks just like chains found on a bike.


Screw drive

This is a continuous thread that connects to the door. Frequently wears out trolley quicker than the chain or belt.


Belt drive

The belt has “teeth” on one side that rotate through a gear on the operator that pulls the trolley. Usually the most expensive option.
