LG Air Conditioner Cassette Air Conditioner Remote Controller

The LG Cassette Air Conditioner Wired Wall Remote Controller (Part Number: AKB73355722) is an authentic original equipment manufacturer (OEM) replacement central control interface designed for LG ceiling cassette, ducted, and commercial HVAC systems. Hardwired directly to the indoor unit control PCB via a multi-core communication cable, this wall-mounted thermostat provides complete management over room temperature setpoints, operation modes (Cool, Heat, Fan, Auto, Dehumidification), multi-stage fan speeds, and airflow vane positioning. Its slim square profile (120 x 120 x 16 mm) and digital interface make it ideal for residential, office, and commercial climate management.

Key Features

• High-Visibility Digital LCD Display: Shows active room temperature, target setpoints, fan speeds, diagnostic error codes, and operational modes at a glance.

• Full-Function Keypad Interface: Dedicated tactile push-buttons provide responsive adjustment for Temperature (Up/Down), Fan Speed, Operational Mode, and Power.

• Pre-Wired 97 cm Communication Cable: Includes an integrated low-voltage wiring harness with a polarized plug-and-play terminal block for direct connection to indoor unit PCB headers.

• Flush Wall-Mount Backplate: Square housing engineered with standard mounting screw holes for clean surface attachment on drywall or standard electrical back boxes.

Benefits

• Solves unresponsive wall thermostats, blank or scrambled LCD readouts, broken keypad buttons, or severed communication wiring.

• Eliminates intermittent signal loss common with handheld infrared remotes by maintaining a direct hardwired connection.

• Direct OEM replacement guarantees factory communication protocols, voltage compatibility, and mounting alignment with LG cassette systems.
