The Sears Craftsman garage door openers are a range of devices for opening and closing garage doors using either belt drive or chain drive systems. As with any mechanical or electrical system, problems can occur. If the door doesn't close there may be a simple solution and it may be worth troubleshooting the problem yourself before calling in a trained technician.
Ensure the opener has power. Plug a lamp or other device into the outlet. If there is no power, check the fuse box.
Check that the garage door spring has not broken.
Wait for 15 minutes then try again. Repeated usage may have caused the motor to overheat and shut down.
Check if the opener lights are blinking. This may indicate a problem with the safety reversing sensors.
Adjust the downward force by turning the force adjustment control counterclockwise with a screwdriver. The force adjustment controls are located on the right side panel of the motor unit. Arrows indicate which control is for "up" and which is for "down."
Tips & Warnings
- Do not attempt to access the electronic components of the device.
- After any adjustment, always check the that safety reversal system is working properly.
