Overview
This genuine OEM single-pole contactor (part number 1050839) is rated 35 amps with a 24-volt control coil for the ICP Tempstar Heil YJ048G condensing unit. The contactor is the electrically operated switch that powers the compressor and condenser fan motor. When the thermostat calls for cooling, the 24V coil pulls the contacts closed and sends line voltage to the compressor; when the call ends, the coil de-energizes and a spring opens the contacts. Because it cycles every time the system runs, the contactor's silver contacts erode, pit, and eventually weld or fail to close — a leading cause of no-cool service calls. Common failure signs include pitted or burned contacts, a buzzing/chattering coil, contacts that stick closed so the unit won't shut off, or a unit that won't start at all.
