The OEM Tempstar 2-Pole 40A Contactor (part number 1172786) is the high-voltage switch that powers the compressor and condenser fan on your T4H560GKD200 heat pump. Its 24V coil is energized by the thermostat call, pulling in the contacts to deliver line voltage to the outdoor loads. Contactors are a high-wear part: the contacts pit and burn from arcing over thousands of cycles, and the coil can fail open. Symptoms of a failing 40A contactor include a unit that hums but won't start, chattering or buzzing at the outdoor unit, welded contacts that keep the compressor running nonstop, or no outdoor operation at all despite a cooling/heating call. A fresh OEM contactor restores clean, reliable switching and protects the compressor from low-voltage and chatter damage.
