ICP 40VA Transformer for WPG3302060RKB1 — 208/230V to 24V | Ships Today

Overview

This genuine OEM control transformer (part #1173691) steps the line voltage down to 24V to power the entire low-voltage control circuit on the ICP/Heil/Tempstar WPG3302060RKB1 packaged unit. It includes the matching 24V barrier/terminal assembly (part #1176032). Every call for heat or cool depends on this transformer: it energizes the thermostat, control board, contactor coil, gas valve, and safety switches. When a transformer fails — usually from a shorted secondary, an overloaded contactor coil, or age — the unit goes completely dead with no thermostat response and no operation. Installing the correct 40VA factory transformer restores full control power.

Specifications

Compatibility

Direct-fit replacement for the ICP unit WPG3302060RKB1 and the shared Heil, Tempstar, Comfortmaker, and Keeprite chassis. Verify the 208/230V primary tap and 40VA rating against your existing transformer before ordering.

Installation Guide

1. Safety First — Disconnect power at the breaker and disconnect; verify zero voltage with a multimeter.
2. Access — Remove the control access panel.
3. Document — Photograph the primary and secondary wiring and tap selection before disconnecting.
4. Remove — Label and disconnect all leads, then unbolt the transformer and barrier from the panel.
5. Install — Mount the new transformer and 24V barrier, matching the correct 208/230V primary tap, and reconnect per your photo.
6. Test — Restore power and meter 24V across the secondary; confirm the thermostat and contactor respond.

Signs You Need a Replacement

• Unit is completely dead — no thermostat or control response
• No 24V reading across the secondary terminals
