Overview
This OEM contactor is the magnetic switch that powers the compressor and condenser fan on your ICP / Tempstar / Heil RHS243L0BA0AAAA heat pump. When the thermostat calls, the 24V control coil pulls the contacts closed and sends line voltage to the outdoor unit. Contactors are among the most common condenser failures — the contacts pit and burn from repeated arcing, and the coil can weaken and lose its pull. Common symptoms include a unit that hums but won't start, an outdoor fan and compressor that stay dead, or audible 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 contactor you are removing.

Compatibility
Fits the ICP, Tempstar, Heil, and Comfortmaker RHS243L0BA0AAAA heat pump condensing unit. The same contactor family is shared 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.
- Remove — Note the line and load terminals and the two 24V coil leads, transfer or label the wires, and unscrew the contactor from its 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
