It signals the control board to interrupt compressor operation whenever pressure moves outside of safe operating limits, protecting expensive components from damage caused by refrigerant faults, airflow restrictions, or condenser problems. This factory switch is calibrated to the exact cut-out and cut-in setpoints your Lennox unit was engineered for.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e If the \u003cstrong\u003eY8802\u003c\/strong\u003e fails, you may experience a system that short-cycles, a compressor that will not start, nuisance lockouts, or a unit that trips out on a pressure fault error.
