Samsung DB92-03442N Air Conditioner Main PCB Assembly

The Samsung DB92-03442N Air Conditioner Main PCB Assembly takes sensor signals that are used to regulate the compressor and fan speed when the appliance is in cooling mode. It uses integrated circuits to track temperature, humidity and pressure indicators and modulates inverter frequency and relay outputs to ensure the required conditions in both indoor and outdoor units in accordance with the settings. Startup, defrost, and shutdown are logic sequences on the microprocessor logic that communicate with wired connections. The assembly is mounted in the evaporator control box that is located inside the building and is connected to the power supply, sensor, and drive components for central control of the system.
