Dual Run Capacitor
The dual run capacitor provides the phase-shift required to generate starting torque for the compressor's induction motor. If the capacitor's dielectric material fails, the compressor will fail to rotate (stalling at Locked Rotor Amps) even while the outdoor fan and indoor blower continue to run, resulting in zero refrigerant compression and no cooling.

AC Contactor
The contactor is an electromechanical relay that closes the 240V circuit to the compressor upon receiving a 24V signal from the thermostat. Over time, the contact points can pit, weld, or develop carbon buildup from arcing, which prevents electrical continuity to the compressor while the rest of the system's low-voltage components remain active.

MERV 11 Pleated Air Filter
A heavily fouled air filter restricts the mass flow of warm air across the evaporator coil, causing the refrigerant temperature to drop below freezing. This leads to ice formation on the coil, which acts as an insulator and eventually blocks all heat transfer, resulting in the system moving air that is not being cooled despite the mechanical components running.
