Electromagnetic Contactor
The contactor is the primary relay that handles high-voltage power. A loud buzz occurs when the solenoid coil fails to generate enough magnetic force to fully seat the armature, or when debris prevents a clean contact, causing the component to vibrate at 60Hz (mains frequency) instead of latching.

Dual Run Capacitor
If the condenser fan is not an ECM, a failed capacitor prevents the creation of a second phase in the motor windings. This results in a stationary magnetic field that causes the motor rotor to vibrate (buzz) without rotating, eventually leading to a thermal cutout.

Hard Start Kit (Start Relay & Capacitor)
This kit provides additional starting torque for the compressor. If the compressor is 'stuck' or struggling against high head pressure, it will emit a loud buzz as it attempts to draw Locked Rotor Amps (LRA) before being tripped by the internal overload protector.
