Overview
This is a genuine OEM single-pole definite purpose contactor (Part #1172472) for the ICP/Tempstar/Heil WJH336000K000A1 heat pump. The contactor is the electromechanical switch that energizes the outdoor compressor and condenser fan whenever the thermostat calls for cooling or heating. When the 24V control coil is energized, the contactor pulls in and closes the line-voltage contacts; when the call ends, the spring opens them. This unit is rated 30 amps with a 24V coil and includes an integrated shunt. Pitted, welded, or chattering contacts are one of the most common reasons an outdoor unit will hum but fail to start, run intermittently, or trip the breaker.

Compatibility
Engineered as the factory-correct contactor for the ICP/Tempstar/Heil WJH336000K000A1. It also serves as a direct replacement across many ICP-family condensers and heat pumps that use a 1-pole, 30A, 24V-coil contactor. Always confirm your existing contactor's amp rating, pole count, and coil voltage match before installing.
Installation Guide
- Safety First – Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
- Access – Remove the condenser unit's electrical access panel.
- Document – Photograph all wire connections before disconnecting anything.
- Remove – Transfer wires one at a time, or label them, then unbolt the old contactor from its bracket.
- Install – Mount the new contactor and reconnect each wire to the matching terminal per your photo.
- Test – Restore power and confirm the contactor pulls in on a call and the compressor/fan start normally.
Signs You Need a Replacement
- Outdoor unit hums or buzzes but the compressor won't start.
- Visible pitting, burning, or melted plastic on the contacts.
- Contactor chatters or fails to pull in fully.
- Contacts have welded shut, leaving the unit running constantly.
