Low Pressure Switch
The low pressure switch is a safety device that opens the electrical circuit if refrigerant pressure falls below a specific PSI. In the GSXC18, if a leak or a restriction (such as a stuck TXV) exists, the board will detect the open switch immediately after the compressor creates a pressure differential, causing an intentional shutdown to prevent compressor vacuum operation.

High Pressure Switch
This switch monitors the discharge side of the refrigeration cycle. If the outdoor condenser fan fails to ramp up or the coils are significantly fouled, the head pressure will spike instantly upon compressor startup; the switch then opens to prevent a catastrophic rupture, signaling the control board to terminate the cycle.

Dual Run Capacitor
The dual run capacitor provides the necessary torque for the compressor and fan motors to operate at correct phase angles. If the capacitance has drifted out of tolerance, the compressor will struggle to maintain rotational inertia, leading to an 'Inrush Current' spike that trips the unit's internal thermal protection or the diagnostic logic of the ComfortBridge board.
