Overview
This OEM control transformer steps 208/230V line power down to the 24V control voltage that runs your ICP WPG3602130LKB1 system's thermostat, contactor coil, gas valve, and control board. Rated at 40VA, it delivers the steady low-voltage supply the control circuit depends on. The kit includes the matching 24V terminal barrier (OEM 1176032) used to land and protect the secondary wiring. When a transformer fails, the entire low-voltage control side goes dead: the thermostat blanks, the contactor won't pull in, and the unit won't start even with high-voltage power present.

Compatibility
Direct-fit replacement for ICP model WPG3602130LKB1 and shared-platform Heil, Tempstar, and Comfortmaker package units using the same 40VA 208/230-to-24V control transformer. Confirm your unit's primary voltage and VA rating against the failed part before installing.
Installation Guide
- Safety First — Disconnect power at the unit disconnect and breaker, then verify zero voltage with a multimeter on both line and low-voltage terminals.
- Access — Remove the service/control panel to reach the transformer.
- Document — Photograph all primary and secondary wire connections before disconnecting.
- Remove — Label and disconnect the 208/230V primary and 24V secondary leads, then unbolt the old transformer and barrier from the panel.
- Install — Mount the new transformer and 24V barrier, then reconnect each lead exactly per your photo, matching primary and secondary taps.
- Test — Restore power and confirm 24V across the secondary and normal system startup.
Signs You Need a Replacement
- Blank thermostat or completely dead control circuit with line power present
- No 24V reading across the secondary terminals
- Contactor or gas valve will not energize
- Burnt smell, discoloration, or a tripped/blown low-voltage fuse
