Craftsman garage door opener flashes and fixes
Craftsman openers report faults by flashing LEDs on the motor unit and by blinking the wall button. The commonest problem is the safety sensors near the floor: both must be lit steadily and aligned, and nothing may block the beam. If the door reverses before it closes, check the sensors first, then the travel limits and force settings.
A remote that stops working needs a new battery and may need reprogramming with the learn button. Never disconnect the safety sensors to make the door close, and leave springs and cables to a trained technician.
Because Craftsman openers have been built by several manufacturers over the years, the learn button color and its location can tell you which family yours belongs to, since different colors indicate different frequencies. Use the color on your opener when you buy remotes or a keypad. Keep a record of the model number from the motor head and any serial number. Replace a worn photo-eye cable promptly, since a damaged wire causes intermittent faults.
Craftsman openers have been sold for decades and made by different companies, so the diagnostic method depends on the model. Many have a learn button with a colored cover that shows the radio type, and an LED that flashes in patterns for faults. Read the model number on the motor head before you choose a code table, and use the color of the learn button when you buy a remote or a keypad.
Common faults are a safety sensor problem, a worn travel limit or a wall control that has lost its connection. The safety sensors must be aligned and their wires intact; a cable with a cut or a staple through it causes intermittent faults. If the wall control does not respond but the remote does, check the two wires at the terminals on the motor head and at the control.
A remote that stops working needs a new battery, and if that fails it should be reprogrammed: press the learn button, then the remote button, as the manual describes. Keep the opener's antenna wire hanging free. If the door has an opener that is more than fifteen years old, consider upgrading to a model with better safety features such as rolling codes and a battery backup.
Why does my Craftsman opener reverse the door?
The safety sensors may be blocked or misaligned, or the force and limit settings may be wrong.
Why does the learn button color matter?
It shows the radio type, so remotes must match it.
