Common Mistakes to Avoid

1. Forcing Bent Rollers

Reason: Attempting to bend rollers back into shape without proper tools or technique can cause further damage or breakage.
Solution: Replace bent rollers instead of trying to straighten them.

2. Ignoring Minor Track Misalignments

Reason: Small misalignments can worsen over time, leading to more significant problems and potential damage to the door or opener.
Solution: Address even minor track bends or misalignments immediately using a track straightening tool or by carefully adjusting the tracks.

3. Using the Wrong Lubricant

Reason: Using the wrong type of lubricant can attract dirt and debris, gumming up the system and reducing its lifespan.
Solution: Use a silicone-based spray lubricant specifically designed for garage door tracks and rollers.

FAQs

How can I tell if my garage door rollers are bent?
Bent rollers often cause noisy operation (squeaking, grinding, or clicking). You can also visually inspect the rollers. Look for any obvious bends or irregularities in the roller's shape. If the roller wobbles when spun, it's likely bent and needs replacing.
