CONTACTOR (Yale YT1703832)

A failing contactor can interrupt electrical current flow, causing intermittent or complete loss of power to connected circuits. This aftermarket replacement part references Yale as the OE maker and cross-references part number YT1703832. The contactor functions as an electrically operated switch that opens or closes a circuit when its coil is energized. Over time, pitted or welded contacts may prevent the switch from disengaging, leading to a stuck-on condition that drains the battery or damages downstream components. Verify the serial number or application, then call (562) 693-7748. A contactor typically handles high-current loads and is rated for a specific voltage and amperage. Its internal coil resistance must match the control circuit voltage to ensure reliable operation.
