Overview

This OEM control transformer assembly (primary part 1173691) steps the 208/230V line voltage of your ICP heat pump down to the 24V control voltage required by the thermostat, contactor coil, and reversing valve solenoid. Rated at 40VA, it supplies stable low-voltage power to the entire control circuit. When a transformer fails — usually from a shorted coil, an overloaded control circuit, or a lightning surge — the system goes completely dead: no thermostat display, no contactor pull-in, and no compressor or fan operation. This OEM kit also includes the reversing valve coil and valve assembly (1172619, 1172618) and the 24V barrier (1176032) used on this heat pump platform.

Compatibility

Direct OEM fit for ICP / Tempstar / Heil heat pump model WJH360000K000A2 and shares components with related WJH-series units. Always confirm your unit's rating plate matches a 208/230V to 24V, 40VA transformer before installing.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter at the contactor line terminals.
Access — Remove the unit's electrical access service panel.
Document — Photograph all primary and secondary wire connections before disconnecting anything.
Remove — Label and disconnect the primary (line) and secondary (24V) leads, then unbolt the failed transformer from the mounting bracket.
Install — Mount the new transformer, reconnect primary and secondary leads exactly per your photo, and confirm primary taps match supply voltage.
Test — Restore power and verify 24V across the secondary and proper thermostat/contactor operation.

Signs You Need a Replacement

Completely dead control circuit — blank thermostat, no contactor pull-in
Repeatedly blown low-voltage fuse on the control board
Measured 0V or unstable voltage on the 24V secondary with line voltage present
Burnt smell or visibly charred transformer windings

Frequently Asked Questions

Does this Transformer fit my ICP WJH360000K000A2 — 40VA 208/230 to 24V | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP WJH360000K000A2 — 40VA 208/230 to 24V | Ships Today. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.

How do I replace the transformer on my ICP WJH360000K000A2 — 40VA 208/230 to 24V | Ships Today?

Difficulty: Medium (30–45 min)
Step 1: Turn off breaker. Step 2: Photo wiring connections. Step 3: Disconnect wires from old transformer. Step 4: Remove mounting hardware. Step 5: Install new transformer, reconnect wires matching voltage ratings. Step 6: Verify 24V output with multimeter.

My thermostat has no power. What failed?

Thermostat with no display = failed 24V transformer (or blown control board fuse). Check the 3A/5A fuse on the control board first ($1–$5 fix). If fuse is good but no 24V output from transformer, replace transformer.

Is this transformer compatible with Bryant or Payne too?

Many ICP parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my ICP transformer?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
