Overview
This is a genuine OEM 40VA control transformer (part number 1173691) with the matching 24V terminal barrier (part number 1176032) for the ICP/Tempstar/Heil WPG3302060LKB1 packaged unit. The transformer steps the 208/230V line voltage down to the 24V low-voltage control circuit that powers the thermostat, gas valve, contactor coil, and control board. When a transformer fails — usually from a shorted secondary, a stuck contactor coil, or an installer wiring error — the entire low-voltage control system goes dead and the equipment will not respond to any thermostat call. A blown transformer is one of the first things to check when a unit has no 24V control power. The included 24V barrier organizes and isolates the secondary terminations for a clean, safe connection.

Compatibility
Factory-correct 40VA control transformer and 24V barrier for the ICP/Tempstar/Heil WPG3302060LKB1 packaged gas unit. Verify your existing primary voltage tap (208 vs. 230) and secondary VA rating before installing.
Installation Guide
- Safety First — Disconnect power at the unit disconnect and verify zero voltage with a multimeter on both line and control terminals.
- Access — Remove the control / electrical compartment service panel.
- Document — Photograph all primary and secondary wire connections and the barrier layout before disconnecting.
- Remove — Label and disconnect the primary (line) and secondary (24V) leads, then remove the transformer mounting screws and old barrier.
- Install — Mount the new transformer, install the 24V barrier, and reconnect primary to the correct voltage tap and secondary to the 24V circuit per your photo.
- Test — Restore power and confirm 24V across the secondary, then run a thermostat call to verify control operation.
Signs You Need a Replacement
- No response to any thermostat call — system completely dead.
- Zero or low voltage measured across the 24V secondary.
- Burnt smell or visible scorching/melting on the transformer body.
- Repeatedly blown control fuse caused by a failing transformer.
