Overview
This OEM 24-volt control transformer supplies the low-voltage power that runs the control circuit of the ICP WPH3362000RKA1 heat pump — energizing the 24V components in this system including the reversing valve coil (1172619 / 1173708), the DPDT control relay (1176137, R8222B1232), and the 24V barrier board (1176148). The transformer steps line voltage down to a clean 24 VAC so the thermostat, contactor coil, and reversing-valve solenoid all operate reliably. Rated at 40VA, it provides enough capacity to hold these control loads in simultaneously without overheating. When the transformer fails, the entire low-voltage side goes dead: the thermostat screen may go blank, the contactor will not pull in, and in heat-pump mode the reversing valve will not shift. Common failure causes are a shorted thermostat wire, a stuck 24V relay or solenoid drawing excess current, or simple age and heat fatigue.

Compatibility
Replacement 24V control transformer for the ICP / Tempstar / Heil WPH3362000RKA1 heat pump and the 24V control circuit that drives its reversing valve coil, control relay, and barrier components. Confirm primary voltage (208/240V) and VA rating before installing.
Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter on both the line and 24V sides.
- Access — Remove the condenser unit's electrical service panel.
- Document — Photograph the primary and secondary wiring before disconnecting.
- Remove — Label and disconnect the primary (line) and secondary (24V) leads, then unbolt the failed transformer.
- Install — Mount the new transformer, land the primary leads on line voltage and the 24V secondary on the control terminals per your photo.
- Test — Restore power and confirm 24 VAC across the secondary, then verify the contactor and reversing valve energize on a call.
Signs You Need a Replacement
- Blank thermostat or dead low-voltage circuit
- Contactor or reversing valve coil won't energize
- No 24 VAC reading across the secondary terminals
- Burned smell, melted housing, or visible scorching
