Overview

This genuine OEM single-pole contactor (PN 1050839) is the main switching relay for the ICP / Heil / Tempstar YK048GC2 heat pump. Rated 35 amps with a 24-volt coil, it closes when the thermostat sends a 24VAC call, sending line voltage to the compressor and condenser fan motor. Over thousands of cycles the silver contacts pit and burn, leading to chattering, welded contacts, or a no-start condition. A failing contactor is one of the most common causes of an outdoor unit that hums but won't run, or one that won't shut off because the contacts have welded closed. Replacing it with the correct 35A, 24V-coil OEM part restores clean, reliable switching.
