My Chamberlain garage door wall button isn't working. What can I do to fix it?

If your Chamberlain garage door wall button isn't working, there are several troubleshooting steps to fix it, as wall button issues are often wiring, power, or button failure. First, check if wall button LED is lit, if not, check power to opener, ensure opener plugged in and outlet has power, as wall button gets power from opener. Second, check wiring connections at wall button and at motor unit, ensure wires securely connected to terminals, loose wires cause wall button not working, tighten screws. Third, check if wall button is locked, some wall controls have vacation lock feature that disables remote and may appear not working, press and hold lock button for 2 seconds to unlock, LED should turn off. Fourth, test wall button by shorting wires at motor unit, disconnect wall button wires at motor unit and short the two terminals with screwdriver, if door operates, wall button itself is bad and needs replacement, wall buttons cost 20 to 50 dollars. Fifth, check for damaged wires, inspect wire run from wall button to motor unit for staples damaging wire or rodent chew, replace wire if damaged. Sixth, power cycle opener by unplugging for 30 seconds, sometimes logic board needs reset. Seventh, check if wall button compatible with your Chamberlain model, older wall buttons may not work with newer openers. If none fix, replace wall control with compatible Chamberlain wall button for your model.
