Overview
This genuine OEM 40VA control transformer (OEM part #1173691) steps 208/230-volt line power down to the 24-volt control voltage used by the contactor coil and low-voltage circuit on the ICP/Tempstar/Heil WPA3304000RKC1. The listing also includes the matching 24V terminal barrier (OEM #1176144, 24-36) for this model so the low-voltage section can be serviced together. The transformer is the foundation of the entire 24V control system — if it opens or shorts, the contactor cannot pull in and the unit goes completely dead even with line voltage present. Transformers commonly fail when a shorted contactor coil or a pinched thermostat wire overloads the secondary, so it is worth checking the rest of the control circuit when one burns out.

Compatibility
Built as the factory control-circuit replacement for the ICP/Tempstar/Heil model WPA3304000RKC1 condensing unit. The 40VA 208/230-to-24V transformer is shared across many ICP-family condensing units and air handlers. Verify OEM part numbers 1173691 and 1176144 against your unit before ordering, and confirm your primary supply is 208/230V.
Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage at the transformer primary leads with a multimeter.
- Access — Remove the unit's electrical service panel to reach the control box.
- Document — Photograph the primary, secondary, and barrier wiring before disconnecting.
- Remove — Tag and disconnect the primary and 24V secondary leads, then unbolt the failed transformer.
- Install — Mount the new transformer, match the 208/230 primary tap to your supply, and reconnect the 24V secondary and barrier per your photo.
- Test — Restore power, confirm a steady 24VAC at the secondary, and verify the contactor pulls in on a cooling call.
Signs You Need a Replacement
- Unit is completely dead with no 24V control voltage
- No measurable voltage at the transformer secondary
- Burnt smell, scorching, or a melted spot on the transformer body
- Repeated blown control fuse or tripped low-voltage circuit
