Q: Why does my garage door start to open and then close again?

Most often, it’s a safety sensor issue or the opener sensing resistance. Check photo eyes for blockage or misalignment, then look for binding, ice at the threshold, or track issues. If it keeps reversing, stop cycling it and book an inspection.

Q: Can I open the garage door manually if the spring is broken?

It is usually not safe. A broken spring makes the door extremely heavy and can cause it to drop suddenly. Avoid forcing it; do not use the opener; and call a technician, especially for double- or insulated doors.

Q: Why does my garage door opener hum, but the door doesn’t move?

The opener is getting power, but the door is not moving due to resistance or a mechanical issue. Common causes include a broken spring, a jammed track, a seized roller, or a worn opener gear. Stop running it repeatedly and schedule service if it won’t move normally.

Q: When should you replace a garage door?

Most garage doors last around 15 to 30 years, depending on use and upkeep. If your door is around 15 years old and repairs are becoming frequent, it’s a good time to start planning for a new one before it becomes an emergency.

Q: How do I know if my garage door needs to be replaced?

Your door usually gives you signs before it fails. If you hear new grinding or scraping noises, notice jerky movement, or see visible damage to panels, rollers, or tracks, the system may be wearing unevenly.

Q: Is it worth repairing a 20-year-old garage door opener?

It can be, if the problem is small and the opener still works reliably overall. But if repairs are getting expensive, parts are hard to find, or it’s struggling to lift the door, replacing it usually makes more sense because newer openers are smoother, safer, and easier to maintain.
