ICP Transformer for WCH5184GKA200 — 24V 40VA Heat Pump | Ships Today

Overview

OEM part 1173715 supplies the 24-volt control power for the ICP / Tempstar / Heil WCH5184GKA200 heat pump, feeding the low-voltage circuit that energizes the reversing valve coil, contactor, and defrost board. The transformer steps line voltage down to a clean 24V at roughly 40VA so the control components actuate reliably. When a control transformer fails, the entire 24V circuit goes dead: no contactor pull-in, no reversing-valve switching, and a heat pump that will not start in either heating or cooling.

Specifications

Compatibility

Sized as the factory 24V control component for the ICP / Tempstar / Heil WCH5184GKA200 heat pump and same-platform ICP-family outdoor units. Confirm secondary voltage and VA rating against your existing part before ordering.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage at the control box with a multimeter.
2. Access — Remove the outdoor unit control-panel service cover.
3. Document — Photograph the primary and secondary leads and their terminal positions before disconnecting.
4. Remove — Disconnect the leads, unbolt the transformer from its mounting bracket, and remove it.
5. Install — Mount the new transformer and reconnect primary and secondary leads to the matching terminals per your photo.
6. Test — Restore power, confirm 24V across the secondary with a meter, and verify the unit responds to a thermostat call.

Signs You Need a Replacement

• No 24V control power and a dead, unresponsive unit.
• Contactor or reversing valve will not energize.
• Blown low-voltage fuse or visibly burned transformer.
• Burning smell or scorched windings at the control box.
