If your garage door opener is completely unresponsive to both the hardwired wall push button and handheld remote controls, the issue is typically caused by a loss of electrical power (such as a tripped circuit breaker, blown fuse, or unplugged power cord), a locked-out safety vacation switch on the wall console, or a complete logic board failure. Callout type="warning" title="Electrical Safety Warning": Verify circuit breaker status safely without touching exposed terminals. Verification: Check that the motor unit's light bulbs or diagnostic LEDs illuminate when power is restored, indicating active electrical connection.
