Dual Run Capacitor (45/5 uF, 370/440V)
The dual run capacitor is responsible for providing the electrical phase shift required to start and run the compressor's induction motor. When the dielectric material within the capacitor degrades, the compressor lacks the torque to overcome head pressure and will fail to start, even though the outdoor fan (which has a lower capacitance requirement) continues to operate. This results in the system 'running' without performing any actual refrigeration work.

Definite Purpose Contactor (2-Pole, 30-40 Amp)
The contactor is the high-voltage relay that closes to power the compressor and fan. Over time, the contact points can develop carbon pitting or 'ants' in the contacts, causing a high-resistance connection that may provide enough current to spin the fan but insufficient amperage to drive the compressor under load. This electromechanical failure prevents the refrigerant cycle from initiating.

Hard Start Kit (Relay and Start Capacitor)
As compressors age, internal friction increases and mechanical tolerances shift, requiring higher initial torque to start. A hard start kit provides an auxiliary boost of capacitance during the first few milliseconds of the startup cycle, allowing a 'stuck' or struggling compressor to overcome inertia that the standard run capacitor can no longer handle.
