Each cooling call from the thermostat energizes the contactor's coil, snapping the contacts closed to start the system. Because it switches high inrush current every cycle, the \u003cstrong\u003e37656\u003c\/strong\u003e is a routine wear item that keeps your air conditioner or heat pump running dependably.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e Watch for pitted or welded contacts, a loud hum or buzz from the outdoor unit, a coil that fails to energize, or ants and debris fouling the contacts.
