The most common reason for a garage door not to open is a broken spring. Whether you have an extension spring system or the more common torsion spring system, these springs do all of the lifting. The operator only pulls the door back. If you have a broken spring you probably heard the big bang and wondered, “What the heck was that?” Fortunately, these springs most often give way when they are loaded, meaning the door is in the down position.
Pressing the wall switch to open the door will only strip the drive gear and add additional cost to your repair. Look above the door and see if you have a broken spring. If you have a broken spring, it’s time to call your friendly neighbourhood garage door technician to install a new spring. If it doesn’t look like a broken spring, it may be the force sensitivity, another safety feature.
The operator is adjusted to open or close with about 15 lbs. of pressure if the spring has lost some of its strength, or if the door has become heavier due to moisture retention in a composite panel wood door. The operator is struggling to lift and will stop dead in its tracks. It may only need a simple adjustment or a general service and spring adjustment. Door # One offers all of these services.
