Overview
This is the genuine OEM single-pole contactor (part number 1173690) for the ICP / Tempstar / Heil WJH360000KTP0A2 condensing unit. Rated at 40A with a 24V coil, the contactor is the electrically operated switch that sends line voltage to the compressor and condenser fan motor whenever the thermostat calls for cooling. The 24V coil energizes from the control transformer, pulling the contacts closed to start the outdoor unit. Over time the contacts pit, burn, or weld from arcing, and the coil can fail open. Symptoms include the outdoor unit not starting on a cooling call, a chattering or buzzing contactor, contacts that stick closed so the unit will not shut off, or visible burning and pitting on the contact faces.

- Access — Remove the condenser control box cover to expose the contactor.
- Document — Photograph all line, load, and 24V coil connections before disconnecting any wires.
- Remove — Transfer wires one at a time or label them, then unscrew the old contactor from its mounting base.
- Install — Mount the new contactor, reconnect line, load, and the 24V coil leads exactly per your photos, and tighten all terminal screws.
- Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the compressor and fan start without chatter.
