Overview
This genuine OEM 40VA control transformer (part number 1173691) steps line voltage of 208/230V down to the 24V control circuit on the ICP/Tempstar/Heil WPG3362060RKB1 furnace, and ships with the matching 24V barrier (part number 1176032). The transformer powers the thermostat, control board relays, gas valve, and other low-voltage components. When a transformer fails — usually from a control-circuit short, a seized contactor coil, or simple age — the entire 24V system goes dead, leaving the furnace completely unresponsive even though line voltage is present. A failed transformer often smells burnt, shows a blown internal fuse link, or reads zero volts on the secondary side. Replacing it with the correct OEM 40VA unit restores power to the control circuit and brings the system back online.

Compatibility
Direct-fit replacement for the ICP/Tempstar/Heil WPG3362060RKB1 furnace control circuit. The 208/230V primary and 24V secondary match the factory wiring, and the included barrier mounts the transformer in its original location. Confirm OEM part numbers 1173691 and 1176032 before installing.
Installation Guide
- Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter on both primary and secondary leads.
- Access — Remove the control/electrical compartment service panel.
- Document — Photograph all primary and secondary wire connections before disconnecting.
- Remove — Disconnect the leads, remove the mounting screws or barrier, and lift out the old transformer.
- Install — Mount the new transformer and barrier, then reconnect each wire exactly per your photo.
- Test — Restore power and confirm 24V across the secondary terminals and normal control operation.
Signs You Need a Replacement
