Overview
This is a genuine OEM single-pole definite-purpose contactor (part #1173690) rated 40 amps with a 24-volt coil, engineered for ICP, Heil, and Tempstar heat pump and condensing units such as the WJH360000K000A2. The contactor is the heavy-duty relay that energizes the compressor and outdoor fan motor whenever the thermostat calls for cooling. A 24V signal from the control transformer pulls the contactor's coil in, closing the line-voltage contacts that feed the compressor. Over thousands of cycles the contacts pit, burn, and weld, and the coil eventually loses its pull. Common failure symptoms include a compressor that hums but won't start, chattering at the contactor, a unit that runs continuously and won't shut off (welded contacts), or no outdoor unit operation at all.

Compatibility
Designed as a direct OEM replacement for the ICP/Heil/Tempstar WJH360000K000A2 and other models in the WJH360000 series that use a 40A 1-pole 24V coil contactor. Always confirm your existing contactor's amp rating, pole count, and coil voltage against the part you are replacing.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter at the contactor terminals.
- Access — Remove the condensing unit service/access panel.
- Document — Photograph every wire and terminal position before disconnecting anything.
- Remove — Transfer line and load wires one at a time, disconnect the two 24V coil leads, and unscrew the old contactor from its bracket.
- Install — Mount the new contactor, reconnect line, load, and 24V coil wires exactly per your photo.
- Test — Restore power, call for cooling, and verify the contactor pulls in cleanly and the compressor and fan start.
Signs You Need a Replacement
