Overview
This OEM control transformer (part #1173691) steps down 208/230-volt line power to the 24-volt control voltage that runs the thermostat, contactor coil, control board, and safety circuits in your ICP WPG3482115LKB1 system. Rated at 40VA, it supplies enough current for the full low-voltage control load. This listing includes the matching 24V terminal barrier/cover (part #1176032) for safe, code-compliant wiring. When a transformer fails — usually from a shorted thermostat wire, a seized contactor coil, or simple age — the entire 24V control circuit goes dead, and the system will not respond to the thermostat at all.

Compatibility
This 40VA 208/230-to-24V transformer is the factory-specified control transformer for the ICP WPG3482115LKB1 and fits many Heil, Tempstar, and Comfortmaker units that use a dual-primary 40VA transformer. Confirm your primary voltage tap (208 vs. 230) before wiring.
Installation Guide
- Safety First — Disconnect power at the breaker and disconnect, then verify zero voltage with a multimeter at the transformer primary.
- Access — Remove the electrical/control access panel.
- Document — Photograph the primary and secondary wiring and the voltage tap selection.
- Remove — Disconnect the primary and 24V secondary leads and unbolt the old transformer from its bracket.
- Install — Mount the new transformer, wire the correct primary tap for your line voltage, reconnect the 24V secondary, and install the terminal barrier.
- Test — Restore power and confirm 24VAC across the secondary and normal thermostat operation.
Signs You Need a Replacement
- System completely unresponsive to the thermostat (no 24V control power).
- No 24VAC measured across the secondary terminals.
- Burnt smell or visibly charred/melted transformer housing.
- Repeatedly blown low-voltage fuse or dead control board.
