There is no single master reset button on a Chamberlain garage door opener. Instead, resetting specific functions requires using dedicated programming controls on the motor housing (located underneath the plastic light lens cover): Press and hold the colored Learn button for 6 seconds to clear all programmed remotes and keypads from memory, or hold it for 10 seconds to reset Wi-Fi network settings. Unplugging the unit for 60 seconds performs a soft power reset of the logic board. Callout type="warning" title="Electrical Safety Warning": Ensure your fingers and tools are kept clear of moving mechanical parts when accessing the motor housing. Verification: Test remote controls or network pairing to confirm previous programming has been erased successfully.
