IFB Air Conditioner DISPLAY CONTROLLER

The IFB Split Air Conditioner Indoor Unit Display Controller PCB Assembly (Part Number: IU221ELDIC010) is an authentic original equipment manufacturer (OEM) replacement user interface module designed for select IFB split AC systems. Mounted behind the front aesthetic panel of the indoor unit enclosure, this circuit board houses the infrared (IR) signal receiver eye, operational status LEDs, emergency manual power button, and a digital 7-segment temperature display. It serves as the primary communication bridge between the user's wireless remote control and the main control motherboard.

Key Features

• Infrared (IR) Signal Receiver: High-sensitivity optical sensor instantly captures and relays wireless remote control commands to the main system control board.

• Digital LED Temperature Readout: Clear, bright 7-segment LED display provides real-time visibility of set temperatures, operating modes, and system error codes.

• Integrated Manual Override Switch: Onboard tactile push-button allows users to turn the air conditioner on or off manually in emergency situations.

• Precision Ribbon/Harness Connector: Secure multi-pin wiring interface ensures low-resistance data and power transfer between the display board and the main control PCB.

• Compact Low-Profile Layout: Engineered specifically to fit behind the curved front plastic louver fascia of compatible IFB indoor chassis units.

Benefits

• Solves symptoms such as the air conditioner failing to respond to remote control button presses, failure to display temperatures, unlit status indicator lights, or a completely dead front display panel.

• Replaces cracked, water-damaged, or electrical-surge affected receiver boards.

• Direct OEM replacement ensures 100% plug-and-play wiring compatibility and exact screw-mounting alignment on the indoor fascia.

Applications

Designed specifically for select IFB split air conditioner models requiring indoor display controller part number IU221ELDIC010.
