ICP Transformer for WPG3304060RKC1 — 40VA 208/230V to 24V | Ships Today

Overview

This OEM control transformer steps down line voltage to the 24V control circuit on your ICP / Heil / Tempstar WPG3304060RKC1 unit. Rated at 40VA with a dual-tap 208/230V primary and a 24V secondary, it powers the contactor coil, control board, thermostat circuit, and safety switches. When the transformer fails, the entire low-voltage system goes dead — no cooling or heating call will energize even though line power is present at the unit. This listing includes the matching 24V barrier (OEM 1178431) used to isolate the transformer's secondary terminals. Common failure signs include a buzzing or humming transformer, a blank thermostat, a repeatedly blown control-board fuse, or a melted/discolored transformer body from a shorted control wire.

Specifications

Compatibility

Engineered as a direct OEM fit for the ICP / Heil / Tempstar / Comfortmaker WPG3304060RKC1 packaged unit. The 40VA 208/230-to-24V transformer is also a common service part across many ICP-family condensers, heat pumps, and packaged systems using the same control platform. Always confirm the part number on your existing transformer before ordering.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage at the transformer terminals with a multimeter.
2. Access — Remove the unit's control-panel service cover.
3. Document — Photograph all primary and secondary wire connections before disconnecting anything.
4. Remove — Label and disconnect the line-voltage primary leads and the 24V secondary leads, then unbolt the old transformer and barrier from the panel.
5. Install — Mount the new transformer and 24V barrier, reconnect the 208/230V primary to the correct tap and the 24V secondary per your photo.
6. Test — Restore power and confirm 24V across the secondary and proper system startup on a thermostat call.

Signs You Need a Replacement

• No 24V control power — thermostat is blank or unit won't respond to a call.
• Audible humming or buzzing from the transformer.
• Repeatedly blown control-board fuse after reset.
• Burnt smell, discoloration, or swollen transformer housing.
