Overview
This OEM control transformer (part 1173691) steps the 208/230V line voltage of the ICP / Heil / Tempstar / Comfortmaker WJA360000KTP0A2 condensing unit down to the 24V control voltage that powers the contactor coil, thermostat circuit, and low-voltage controls. Rated at 40VA, it delivers stable low-voltage power to the unit's switching components. The listing includes the matching 24V terminal barrier (part 1176032) that insulates and protects the secondary connections. A failed transformer is a leading no-cooling cause: when it opens, the contactor never energizes and the compressor and condenser fan stay off even though the thermostat is calling.

Installation Guide
- Safety First — Disconnect power at the disconnect and breaker and verify zero voltage with a multimeter before touching any wiring.
- Access — Remove the condenser control panel cover.
- Document — Photograph the primary (line) and secondary (24V) leads before disconnecting.
- Remove — Disconnect the primary and secondary wires and unbolt the old transformer and barrier from the panel.
- Install — Mount the new transformer and 24V barrier, then match the 208/230V primary leads and 24V secondary leads per your photo.
- Test — Restore power, confirm 24V at the secondary, and verify the contactor energizes on a cooling call.
Signs You Need a Replacement
- No 24V output measured at the secondary terminals
- Contactor will not pull in despite a thermostat call for cooling
- Burnt smell or visible scorching on the transformer windings
- Repeated blown low-voltage fuses or tripped control circuit
