The answer to 'why is my smoke detector outlet not working' is that there could be several common causes, including a tripped circuit breaker, a faulty electrical outlet, or an issue with the smoke detector itself. Smoke detectors are typically wired directly into your home's electrical system, so if the outlet is not working, the smoke detector will not receive power and will not function properly.
Some common symptoms of a non-working smoke detector outlet include the smoke detector not powering on, no lights or indicators on the detector, and the detector not responding when tested. To troubleshoot, you'll want to first check the circuit breaker to ensure it has not tripped. If the breaker is fine, you can try testing the outlet with a voltage tester or plugging in another device to see if the outlet is receiving power. If the outlet is not working, you may need to replace it. If the outlet is working but the smoke detector is still not powering on, the smoke detector itself may be faulty and need to be replaced.
