How Do You Troubleshoot A Humming Motor In A Craftsman Garage Door Opener?
A humming motor in your Craftsman garage door opener is usually the result of a burned-out capacitor, although it could also be the result of other problems. In the capacitor is defective, the best course of action is to call a trained garage door technician to replace the part. But there are a few steps you can take to troubleshoot the issue before you make the call. Close the garage door and disconnect the trolley by releasing the emergency handle. Broken springs may be making the motor of your garage door opener hum briefly before it stops working. Manually open and close the door. If the door does not stay open, though it’s supported by its springs, disconnect the garage door opener. Do not apply more force to try to operate the opener. Instead, call for professional garage door service. Disable the door lock, if the problem happens in operating the opener on first attempt. The door might be locked.
