Craftsman Garage Door Opener Opens But Does Not Close: How to Fix

A Craftsman garage door opener that opens but does not close can be a frustrating problem. However, it is usually an easy fix. In this article, we will walk you through the steps to troubleshoot and fix a Craftsman garage door opener that opens but does not close.

Craftsman Garage Door Opener Opens But Does Not Close

Common Causes

There are several common causes of this problem. The most likely cause is a problem with the safety sensors. These sensors are designed to prevent the garage door from closing if an object is in the way. If the sensors are blocked or out of alignment, the door opener will not close.

Other possible causes include:

  • A problem with the motor or drive train
  • A problem with the control board
  • A problem with the wiring

Troubleshooting

The first step is to identify the cause of the problem. Here are some things you can check:

Safety Sensors

  • Make sure that the sensors are not blocked by anything. Check for objects that may be blocking the light beam between the sensors. This could include toys, furniture, or even a pet.
  • Check that the sensors are aligned properly. The sending sensor should be mounted at the top of the door frame, and the receiving sensor should be mounted on the garage door itself. The sensors should be aligned so that the light beam is broken when the door is closed. You can check the alignment by shining a flashlight at the sensors. If the receiving sensor does not detect the light emitted by the sending sensor, it indicates a misalignment between the sensors.
