Garage Door Maintenance Checklist
Use this maintenance checklist to reduce emergency failures and extend the life of springs, rollers, tracks, and opener systems.
What You Need to Know
Monthly Checks
Listen for unusual noise, verify smooth travel, test photo eyes, and inspect visible hardware for looseness or wear.
Quarterly Checks
Lubricate moving metal components, inspect weather seals, and confirm the door remains balanced during manual operation.
Safety Tests
Test auto-reverse and sensor interruption behavior. If the opener fails safety tests, stop use and schedule service.
Annual Professional Tune-Up
A yearly tune-up helps catch fatigue in springs, cables, rollers, and hinges before failure causes an emergency.
Need Professional Help?
For safety-critical issues or uncertain diagnosis, schedule a professional inspection before forcing operation.
