How should you troubleshoot a Craftsman garage door opener?

Answer

If you have problems with your Craftsman garage door opener, the best place to start troubleshooting is using the instruction manual that you received during installation. However, if you've misplaced your manual, there are some solutions you can try.

If the remote opener doesn't work and the power button isn't lit, try changing the batteries or adjusting them to make sure the terminals are connected. If the wall-mounted opener is not working, try restarting the system by turning off the circuit breaker that connects power to the opener. Apply a small amount of lubricant to the track if the door is having difficulty moving smoothly. Check that the optical sensors at the bottom of the door opening are aligned, as even minor misalignments can cause the system to shut down. If none of these solutions work and you notice a scraping or grinding noise, there may be something wrong with the gears or the motor, which requires the intervention of a skilled mechanic who can diagnose the problem and replace parts in the motor.
