The answer to 'smoke detector keeps tripping' is that there are several common causes, including dust buildup, humidity, or a faulty detector. Smoke detectors can be sensitive to environmental conditions and may trip frequently if not properly maintained.
To troubleshoot, first try cleaning the smoke detector by gently vacuuming or wiping it down. If that doesn't work, you may need to replace the batteries or the entire unit. If the problem persists, it's best to call a professional electrician to diagnose and fix the issue, as they can properly inspect the wiring and ensure the detector is functioning correctly.
