One common problem is the motor slowing or failing to work when you press the remote control. This often signals a replacement of the motor and sometimes one or more broken or stretched cables and/or photo eye sensors (located on each side of the garage door at the bottom). The repair is fairly simple since most openers lift only one section of your garage door; however, there are exceptions to this rule. Therefore, it is important to know which type of opener you have before attempting any repairs.
