ICP 2-Pole 30A Contactor for RGS120LEBA0AAA – 24V Coil | Ships Today

Overview

This OEM 2-pole, 30-amp contactor with a 24-volt coil (OEM 1178074) for the ICP/Tempstar/Heil RGS120LEBA0AAA is the electromechanical switch that energizes the line-voltage components on demand from the 24V control circuit. When the thermostat calls, the 24V coil pulls the contactor armature in, closing both poles and delivering full line power. Contactors are high-wear items: the contacts arc every cycle, gradually pitting and burning until they weld shut (system runs constantly) or fail to close (system won't start). A buzzing or chattering coil signals a weak contactor that should be replaced before it strands the equipment. This factory-spec 30A/24V unit restores reliable switching.

2. Access – Remove the electrical control box service panel.
3. Document – Photograph all line, load, and 24V coil wiring before disconnecting.
4. Remove – Label and disconnect each wire, unscrew the old contactor from its mounting rail.
5. Install – Mount the new contactor, transfer each wire to the matching terminal per your photo, and torque connections.
6. Test – Restore power, initiate a call for cooling/operation, and confirm both poles close cleanly with no chatter.
