Overview
This genuine OEM control transformer kit for the ICP/Tempstar/Heil WPG3362090RKB1 package unit includes the 40VA step-down transformer (PN 1173691) and its 24V barrier/cover (PN 1176032). The transformer steps the 208/230V line voltage down to the 24V control voltage that powers the thermostat, control board, contactor coil, and gas valve. The included barrier provides safe isolation and protection for the secondary connections. A failed transformer takes the entire low-voltage control circuit offline — the thermostat goes dark, the contactor won't pull in, and the unit appears completely dead even though line power is present. Transformers commonly fail from a shorted 24V circuit, age, or a power surge.

Compatibility
Direct-fit replacement for the ICP/Tempstar/Heil WPG3362090RKB1 package unit and other ICP-family units using a 40VA, 208/230-to-24V transformer with barrier PN 1176032. Confirm primary voltage taps and VA rating against your existing transformer before ordering.
Installation Guide
- Safety First — Disconnect power at the disconnect and breaker; verify zero voltage on both primary and secondary with a multimeter.
- Access — Remove the control/electrical service panel.
- Document — Photograph the primary (line) and secondary (24V) leads and the barrier placement before disconnecting.
- Remove — Disconnect the primary and secondary wires, remove the barrier, and unbolt the old transformer.
- Install — Mount the new transformer, wire the correct primary tap for your supply voltage, reconnect the 24V secondary, and fit the barrier per your photo.
- Test — Restore power and confirm ~24VAC at the secondary and that the thermostat and controls power up.
Signs You Need a Replacement
- Thermostat is blank and the unit is completely unresponsive
- No 24V output measured at the secondary terminals
- Burnt smell or visible scorching/melting on the transformer
- Repeated control-fuse blowing after a low-voltage short is corrected
