- Identify signs of bigger problems – like broken springs or cables
- Avoid dangerous DIY mistakes – especially with high-tension parts
Sometimes, yes — especially if it’s a sensor issue, battery, or remote setting. But anything involving springs, cables, or door alignment should only be handled by a trained tech.
