<br>When a door won’t lift, a tech releases tension safely, [A1Garage.com](http://jiebbs.cn/home.php?mod=space&uid=485404&do=profile&from=space) replaces matched springs and cables, inspects drums and bearings, and resets balance so the door holds mid-travel. Tracks are [leveled](https://www.houzz.com/photos/query/leveled) and rollers lubricated for smooth motion. If the opener grinds, a belt-drive with soft-start is a strong upgrade. Finish with sensor alignment, force/limit tests, and an emergency-release check. A seasonal tune keeps parts clean and prevents surprise breakdowns. schedule service |
