ICP 2-Pole 30A Contactor for RHS036L0XA0AAAA — 24V Coil | Ships Today

Overview

This genuine ICP 2-pole definite-purpose contactor (OEM part 1178074) is the electromechanical switch that energizes your outdoor condensing unit. Rated for 30 amps with a 24-volt control coil, it receives the low-voltage call from your thermostat or control board and closes its contacts to send line voltage to the compressor and condenser fan motor. When a contactor fails, the system either won't start at all or the contacts weld shut and the unit runs continuously. Pitted, burned, or chattering contacts are the most common cause of a no-cooling service call on this equipment.

Specifications

Compatibility

Engineered as a direct OEM replacement for ICP/Heil/Tempstar/Comfortmaker model RHS036L0XA0AAAA and many related condensing units and heat pumps that use a 2-pole, 30A, 24V-coil contactor. Always confirm the coil voltage and amp rating against the part you are removing.

Installation Guide

1. Safety First — Disconnect power at the outdoor disconnect and verify zero voltage at the contactor terminals with a multimeter.
2. Access — Remove the service panel on the condensing unit.
3. Document — Photograph all wire connections before disconnecting.
4. Remove — Disconnect line, load, and 24V coil leads; unscrew the old contactor from the bracket.
5. Install — Mount the new contactor and reconnect each wire exactly per your photo.
6. Test — Restore power, call for cooling, and confirm the contacts pull in cleanly with no chatter.

Signs You Need a Replacement

• Outdoor unit won't start even though the thermostat is calling for cooling.
• Buzzing, humming, or chattering noise from the contactor.
• Visible pitting, burning, or melted plastic on the contacts.
