Overview
This OEM single-pole definite purpose contactor (part #1172472) is the electrical switch that energizes the compressor and condenser fan motor in your ICP WPA4364000RKB1 condensing unit. Rated for 30 amps with a 24-volt control coil and an integrated shunt, it closes when the thermostat calls for cooling and passes line voltage to the compressor. A failed contactor is one of the most common no-cool service calls — the points pit, weld, or chatter, leaving the outdoor unit silent or buzzing while the indoor blower runs normally. Symptoms include a humming sound at the unit, burnt or melted contact points, and a compressor that won't start even though 24V is present at the coil.

Compatibility
Engineered as a direct-fit replacement for the ICP WPA4364000RKB1 condensing unit and shared across many Heil, Tempstar, and Comfortmaker outdoor units that use a 30A 1-pole 24V contactor. Always confirm your existing contactor's amp rating, coil voltage, and pole count against the specs above before installing.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter before touching any terminals.
- Access — Remove the condensing unit's service/access panel.
- Document — Photograph every wire and terminal position before disconnecting anything.
- Remove — Label and disconnect the line, load, and 24V coil wires, then unscrew the old contactor from its bracket.
- Install — Mount the new contactor and reconnect each wire exactly per your photo (line in, load to compressor/fan, 24V to coil terminals).
- Test — Restore power and call for cooling; confirm the contactor pulls in cleanly and the compressor and fan start.
Signs You Need a Replacement
- Outdoor unit hums or buzzes but the compressor won't start
- Pitted, burnt, or welded contact points
- Chattering or rapidly cycling contactor
