Pressure switches monitor refrigerant circuit pressures and signal the control board to allow or interrupt operation. When either switch fails or trips, the system will lock out before completing a heating or cooling cycle, often displaying a fault code or simply refusing to start. Common symptoms include the unit short-cycling, failing to enter the heating or cooling stage, or tripping the system into a continuous fault lockout.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e HK02ZA395 — High Side Pressure Switch | HK02ZB028 — Low Side Pressure Switch | Factory-calibrated trip points | Spade terminal connectors | Designed for R-410A refrigerant systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are calibrated to exact factory trip pressures, ensuring your system protects the compressor at the correct threshold. Generic alternatives often use looser tolerances that can allow operation outside safe pressure ranges, risking compressor damage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 3\/5\u003c\/strong\u003e — Refrigerant circuit must be depressurized before replacing pressure switches.
