Overview
This OEM control transformer steps down the incoming 208/230V line voltage to the 24V low-voltage power that runs the thermostat, contactor coil, control board, and safety circuits on your ICP WPG3482130RKB1 system. Rated at 40VA, it supplies enough current to energize multiple 24V loads simultaneously. The kit includes part 1173691 (TRANS 208/230>24 40VA) and the 1176032 24V barrier. A failed transformer is one of the most common causes of a completely dead control circuit: the blower, compressor, and thermostat all go silent even though line power is present. Common failure modes include an open primary or secondary winding, a shorted winding that trips a fuse, or a burned-out unit caused by a short downstream in the 24V wiring.

Compatibility
Engineered for the ICP / Tempstar / Heil / Comfortmaker WPG3482130RKB1 and other units in the same family that use a 40VA, 208/230V to 24V control transformer. Always verify your existing transformer's VA rating and primary/secondary voltages before ordering.
Installation Guide
- Safety First - Disconnect power at the breaker/disconnect and verify zero voltage with a multimeter before touching any wiring.
- Access - Remove the service panel to reach the control compartment.
- Document - Photograph all primary and secondary wire connections before disconnecting anything.
- Remove - Label and disconnect the primary and secondary leads, then unbolt the old transformer from its mounting bracket.
- Install - Mount the new transformer, reconnect the primary to line voltage and the secondary to the 24V circuit exactly per your photo, and install the 24V barrier.
- Test - Restore power and confirm 24V at the secondary and normal thermostat/contactor operation.
Signs You Need a Replacement
- Thermostat is blank and the entire 24V control circuit is dead
- No voltage at the secondary terminals when line voltage is present
- Blower and compressor will not energize despite a call for heat or cool
- Repeated blown low-voltage fuses or a visibly burned/smelling transformer
