A working smoke detector can be a lifesaver, but when it starts beeping at three in the morning, you probably feel more like ripping it out of the ceiling. If you’re tired of waking up to a chirping smoke detector, try these steps to get it working again.

1) Replace the Battery

The most common reason a smoke detector chirps intermittently is a dying battery. These 9-volt lithium batteries can last up to 10 years in new smoke detectors, saving you the annual replacement necessary with most batteries.

2) Remove Dust

If a new battery doesn’t stop the beeping, your smoke detector may need a thorough cleaning. To remove dust and debris from the smoke detector, use a can of compressed air. Simply unscrew the smoke detector, remove the battery, and spray the air into the battery compartment, the detection vent, and any openings.

3) Inspect the Wiring

If you replace the battery and clean the smoke detector but it just won’t stop beeping, it may be time to call in a professional. A wiring or circuitry issue could be causing your smoke detector to malfunction. Smoke detectors also wear out every five to seven years, and need to be replaced. An electrician can diagnose and fix the issue, and help you install a new smoke detector.
