Overview
This OEM contactor is the magnetic switch that powers the compressor and condenser fan on your ICP / Tempstar / Heil RHS243L0CA0AAAA heat pump. When the thermostat calls for cooling or heating, the 24V control coil pulls the contacts closed and sends line voltage to the outdoor unit. Contactors are one of the most common failure points in an outdoor condenser — the contacts pit and burn from constant arcing, and the coil can lose its magnetic pull. Typical symptoms include a unit that hums but won't start, an outdoor fan and compressor that won't energize, or chattering at the contactor. This listing covers the OEM contactors used on this model: 2-pole 30A, 3-pole 40A, and 3-pole 60A — all with a 24V coil. Match the pole count and amp rating to the part you are removing.

Compatibility
Fits the ICP, Tempstar, Heil, and Comfortmaker RHS243L0CA0AAAA heat pump condensing unit. The same contactor family is used across many RHS-series outdoor units. Confirm the existing contactor's pole count and amperage before ordering.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
- Access — Remove the condenser service panel to expose the electrical compartment.
- Document — Photograph every wire and terminal on the old contactor before disconnecting anything.
- Remove — Note the line (L1/L2) and load (T1/T2) terminals and the two 24V coil leads, then transfer wires one at a time or label them. Unscrew the contactor from the bracket.
- Install — Mount the new contactor, reconnect each wire exactly per your photo, and confirm the 24V coil leads are landed correctly.
- Test — Restore power and call for cooling; verify the contacts pull in cleanly and the compressor and fan start.
Signs You Need a Replacement
- Pitted, burned, or welded contacts
- Unit hums but the compressor and fan do not start
- Loud chattering or buzzing at the contactor
- Coil reads open or out of spec on a meter
