🛡️ Prevention Tips
How to prevent your garage door opener's not opening from happening again after this repair.
Lubricate the chain, rollers, and hinges every 6 months with garage door lubricant (not WD-40).
Test the safety sensors monthly by placing an object in the door's path — the door should reverse immediately.
Don't disengage the emergency release unless necessary, and never pull it while the door is open.
Check torsion springs for signs of wear or rust annually. Springs have a finite cycle life and fail without warning.
After completing this repair, make a note of the date and the part replaced. Tracking repairs helps you spot recurring issues before they become major failures.
