Defrost Control Board
The defrost control board is the logic center that monitors safety switches and manages the compressor contactor. A failure in the board's micro-processor or its integrated short-cycle timer relay will cause the unit to drop the contactor signal immediately after initiation, effectively shutting down the system as soon as it attempts to ramp up. This is a high-frequency failure point in Goodman GSZ series units where logic drift causes premature safety lockouts.

Dual Run Capacitor
The dual run capacitor provides the phase-shifted electrical charge necessary to maintain the magnetic field in the compressor's start windings. If the capacitor is out of its +/- 5% microfarad tolerance, the compressor will fail to maintain sufficient torque under the initial head pressure, causing it to draw locked-rotor amps (LRA) and trip either the internal thermal overload or the control board's current-sensing logic.

High Pressure Switch
The high pressure switch is a safety device that opens the 24V control circuit if refrigerant pressure exceeds safety thresholds. Over time, the internal diaphragm can weaken or the electrical contacts can become resistive, causing a 'nuisance trip' where the initial pressure surge during startup triggers the switch to open, instantly breaking the circuit to the compressor contactor.
