Overview
This OEM 2-pole definite purpose contactor (part number 1178074) is the electromechanical switch that energizes the compressor and condenser fan circuits in your ICP Tempstar Heil RGS102LECB0AAA system. Rated for 30 amps with a 24-volt control coil, the contactor pulls in when the thermostat calls for cooling, closing its contacts to send line voltage to the high-current loads. Over thousands of cycles the contacts pit, burn, and weld; the coil can also fail open. Common failure symptoms include a system that won't start, a chattering or buzzing sound at the contactor, contacts that stay closed so the unit never shuts off, or visible arcing and burnt terminals.

Compatibility
Engineered as a direct OEM replacement for the ICP Tempstar Heil RGS102LECB0AAA furnace/condensing unit. Also fits many ICP-family models across the Tempstar, Heil, and Comfortmaker lines that share the same 2-pole, 30A, 24V contactor footprint. Verify your old part is stamped 1178074 or that the original is a 2-pole 30A unit with a 24V coil before installing.
Installation Guide
- Safety First — Disconnect power at the breaker and disconnect, then verify zero voltage with a multimeter at the contactor terminals.
- Access — Remove the unit's electrical service panel.
- Document — Photograph all wire connections to the line, load, and coil terminals before disconnecting.
- Remove — Label and disconnect each wire, then unscrew the old contactor from its mounting bracket.
- Install — Mount the new contactor and reconnect every wire exactly per your photo; confirm the 24V coil leads land on the coil terminals.
- Test — Restore power and call for cooling; confirm the contactor pulls in cleanly with no chatter and the compressor/fan energize.
Signs You Need a Replacement
- Buzzing, humming, or chattering noise from the contactor
- Compressor and fan won't start even with a cooling call
- System runs continuously because contacts are welded shut
- Visibly pitted, burnt, or arced contacts and terminals
