Emerson 380 Door Chime

The Emerson 380 Door Chime is a commercial-grade electronic bell assembly that uses an internal transformer and relay to drive the chime tone when its switch is actuated. Common failures in this class include worn or corroded contacts on the push‑button, burnt-out relays or MOSFETs, and capacitor degradation causing continuous looping of the chime sequence. Check the power supply voltage at the transformer terminals, inspect the button contacts for continuity and corrosion, and verify that the relay coil is energizing correctly; if the unit continues to cycle after a switch replacement, examine the control logic board for shorted traces or damaged ICs.[oss-gpt-20b]
