Restore the structural protection and secure mounting of your systems electronics with the Samsung Air Conditioner Case-PCB Assembly DB90-06115C. This specialized enclosure acts as the protective housing for the indoor units main control board, shielding sensitive microprocessors and electrical traces from dust, moisture, and accidental physical contact. It is engineered to provide a stable foundation that prevents the PCB from vibrating or shifting during the high-speed operation of the blower motor. If your current housing is cracked, melted due to an electrical fault, or has broken mounting tabs that prevent the board from staying in place, replacing this case is essential for long-term reliability.

The DB90-06115C is manufactured from high-grade, flame-retardant plastic designed to meet strict safety standards for electronic components. Its precision-molded design includes specific cable routing channels and snap-fit clips that ensure all wiring harnesses are managed neatly and kept away from moving parts like the louver motor or fan.

Installation / Replacement Instructions

1. Safety First: Turn off the air conditioner and completely disconnect the power supply at the main circuit breaker.

2. Access the Internals: Open the front intake grille and remove the air filters. Unscrew and remove the main front panel housing to expose the internal chassis of the indoor unit.

3. Locate the Control Box: Identify the existing PCB case on the right side of the unit. Remove any external metal or plastic covers protecting the main control area.

4. Document and Disconnect: Take high-resolution photos of the wiring and PCB orientation. Carefully unplug all harnesses from the board and remove any mounting screws holding the PCB inside the old case.

5. Remove the Old Case: Unscrew the fasteners securing the DB90-06115C assembly to the unit chassis. Carefully detach it, taking note of how the wires were routed through the side ports.

6. Install the New Case: Align the new DB90-06115C with the chassis mounting points and secure it with the original screws. Place the PCB into the new housing, ensuring it snaps firmly into the internal clips or aligns with the screw holes.

7. Reconnect and Reassemble: Route the wiring harnesses through the designated ports and plug them back into the PCB. Replace the control box covers and the units front housing. Restore power and verify the unit operates smoothly.

Compatible with select Samsung split-system indoor units, this OEM-quality PCB case assembly restores the secure mounting and electrical insulation originally designed for your system.
