Together, these switches monitor refrigerant-side pressures and protect the compressor by cutting power when operating pressures fall outside safe limits. A failed high-side switch causes nuisance lockouts and no-cooling complaints; a failed low-side switch typically triggers fault codes related to low refrigerant or loss of charge. Replacing both switches simultaneously eliminates repeat service calls and restores full system protection.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs — High Pressure Switch (HK02ZA395):\u003c\/strong\u003e Opens at 395 PSI | Closes at 295 PSI | 240 VAC rated | 1\/8\" NPT male thread | Sensata PS80-03-0018 platform | Replaces legacy Carrier P\/Ns 312926-217, HK02ZA380, HK02ZA396, HK02ZA400, and more\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs — Low Pressure Switch (HK02ZB044):\u003c\/strong\u003e Opens at 7 PSI | Closes at 22 PSI | 24V coil circuit | 50\" lead length | Drop-in OEM replacement — meets exact factory design specifications for optimum system performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM Carrier pressure switches are manufactured to exact cut-in and cut-out tolerances, preserving equipment warranty and maintaining agency safety listings.
