Overview
This OEM single-pole definite purpose contactor (part number 1172472) is the electrical switch that powers the compressor and condenser fan motor in your ICP / Tempstar / Heil WCA5184GKA101 condensing unit. On a cooling call, the 24-volt coil pulls in the main contacts and routes line voltage to the outdoor components. Rated for 30 amps and fitted with a shunt, it safely carries and switches the full inductive load of the system. Because the contacts arc on every cycle, contactors are a common wear item. Failure symptoms include pitted or welded contacts, a buzzing or chattering coil, an outdoor unit that won't start, or a condenser that runs continuously. A new contactor restores reliable starting and protects the compressor from chatter and voltage drop.

Compatibility
Direct OEM fit for the ICP / Tempstar / Heil model WCA5184GKA101 condensing unit. This is the factory-specified contactor for that system and a correct replacement across many ICP-family air conditioners and heat pumps that shipped with part 1172472. Verify your existing contactor is a 1-pole, 30A unit with a 24V coil before installing.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage at the contactor terminals with a multimeter.
- Access — Remove the condensing unit service panel to reach the electrical compartment.
- Document — Photograph all wire positions before disconnecting anything.
- Remove — Note the line, load, and 24V coil leads, disconnect them, then unscrew and lift out the old contactor.
- Install — Mount the new contactor and reconnect each wire exactly as shown in your photo.
- Test — Restore power and start a cooling call; confirm the coil pulls in smoothly and the compressor and fan operate.
Signs You Need a Replacement
