This could be caused by a faulty component, a loose connection, or the detector simply reaching the end of its lifespan.

Some common causes include a malfunctioning circuit board, a worn-out battery, or dust buildup inside the detector. The smell may also indicate that the smoke detector is overheating and could potentially catch fire if not addressed promptly.
