Overview
This OEM contactor set covers both switching contactors used in your ICP Tempstar Heil RGS300HDEA0AAAA unit: part #1171554 (2-pole, 30 amp, 24V coil) and part #1183142 (3-pole, 60 amp, 24V coil). A contactor is the electrically operated switch that connects line voltage to the compressor and condenser fan when the thermostat calls for cooling. The 24V coil pulls the contacts closed; the heavy silver contacts then carry the full running current. Over thousands of cycles those contacts pit, burn, and weld, and the coil can fail open. Symptoms of a failing contactor include a unit that won't start, a loud hum or chatter from the contactor, contacts that stick closed and keep the compressor running, or visible arcing and burnt terminals. Replacing with correctly rated OEM contactors restores clean, reliable switching and protects the compressor.

Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
- Access — Remove the unit's electrical-access panel.
- Document — Photograph all line, load, and 24V coil wiring before disconnecting.
- Remove — Transfer wires one at a time or label them, unscrew the old contactor, and lift it out.
- Install — Mount the new contactor and reconnect each lead exactly per your photos.
- Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and energizes the load.
Signs You Need a Replacement
