When your thermostat calls for cooling, the contactor's coil pulls its contacts closed to send line voltage to the compressor. The integrated auxiliary switch provides the additional switching your Lennox control circuit relies on for proper sequencing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A worn \u003cstrong\u003e48G59\u003c\/strong\u003e contactor may show pitted or burned contacts, chatter or buzz loudly, or weld shut so the outdoor unit runs constantly. Failed contactors can also prevent the unit from starting at all, cause intermittent cooling, or trip breakers due to arcing at the contacts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The authentic Lennox \u003cstrong\u003e48G59\u003c\/strong\u003e is built to the exact coil voltage, amperage rating, and auxiliary-switch configuration your system requires.
