Inverter Control PCB
This board manages the variable speed compressor using Insulated Gate Bipolar Transistors (IGBTs). Constant thermal expansion and contraction during variable frequency operation can lead to micro-fractures in the solder pads or component degradation within the power module. Replacing this board restores the high-voltage DC conversion necessary to drive the inverter compressor.

Main Control PCB
The main logic board processes thermistor data and communication signals from the indoor unit. Logic failure often occurs due to electrostatic discharge or electrolytic capacitor drying, which prevents the unit from executing its startup sequence. A new board ensures correct signal processing and communication between the thermostat and the inverter.

Noise Filter/Surge PCB
This board acts as a sacrificial barrier against line-side voltage transients and filters electromagnetic interference (EMI). If the user reports a complete loss of communication or power to the subsequent boards, the Varistors or inductors on this board have likely failed. Replacing it restores clean power to the primary control electronics.
