The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes its contacts to supply line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted contacts, a burned coil, or a stuck plunger — the system will either refuse to energize entirely, run continuously without cycling off, or produce a loud chattering noise from the control panel.

Generic contactors frequently use lower-grade contact alloys that pit rapidly under compressor inrush current, leading to premature failure within one to two seasons.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Always disconnect power at the breaker and verify zero voltage with a multimeter before touching any terminals.
