LG Refrigerator PCB Assembly,Sub

The LG Refrigerator Door Alarm Buzzer PCB Assembly (Part Number: EBR64730423) is an authentic original equipment manufacturer (OEM) replacement electronic component designed for LG refrigerators. Installed within the display console or main control board housing, this specialized sub-PCB features an integrated piezo-electric buzzer element and multi-pin terminal headers. When triggered by the door switch sensor after a set period, the module sounds a warning alarm to notify users that the refrigerator door has been left open, preserving internal cooling temperatures and protecting groceries from spoilage.

Key Features

• OEM Audible Alarm Alert: Factory-tuned piezo buzzer produces clear, audible warning tones when door closure signals are interrupted.

• Integrated Terminal Sockets: Features color-coded (red and white) multi-pin PCB socket connectors for direct, secure wiring harness connection.

• Durable Electronic Sub-Board: High-reliability printed circuit board layout designed to withstand continuous power cycles and ambient humidity fluctuations.

Benefits

• Solves missing door open alarm chimes, faint/distorted buzzer sounds, or persistent alarm errors.

• Helps conserve electricity and maintain internal freshness by preventing prolonged warm air intrusion.

• Direct OEM replacement guarantees exact plug-and-play connector fitment and seamless communication with the main microcomputer.
