Could a failing Dual Run Capacitor cause the BRYANT PREFERRED 16 (116B/226C) to have symptom: Starts Then Shuts Off?

The capacitor provides the necessary phase-angle shift to the compressor's start windings; if the capacitance has drifted outside of the ±5-10% tolerance, the compressor will fail to stay in sync or draw excessive amperage. This high current draw triggers the internal thermal protector or the control board's current sensor, causing the unit to shut down almost immediately to prevent winding insulation failure.

Could a failing High Pressure Switch cause the BRYANT PREFERRED 16 (116B/226C) to have symptom: Starts Then Shuts Off?

This safety device monitors the discharge pressure of the refrigerant; if the outdoor fan motor fails or the coil is severely restricted, head pressure spikes. The switch is designed to mechanically open the control circuit when pressures exceed safe thermodynamic limits, resulting in an immediate system shutdown to protect the compressor valves.

Could a failing InteliSense Control Board cause the BRYANT PREFERRED 16 (116B/226C) to have symptom: Starts Then Shuts Off?

On Preferred 16 models equipped with InteliSense, the main logic board interprets data from various thermistors and sensors. If the board detects an illogical temperature spread or a failing relay contact (pitting), it will terminate the cooling cycle as a preventative measure, often resulting in a 'start-stop' behavior before a hard lockout occurs.
