Overview

This is a genuine OEM 40VA control transformer for the ICP/Heil/Tempstar WJH336000KTP0A2. It steps 208/230V line voltage down to the 24V control circuit that powers the thermostat, contactor coil, reversing valve coil, and safety controls. Rated at 40VA, it supplies enough current to energize the reversing-valve solenoid and contactor simultaneously without sagging. When the transformer fails — open primary, shorted winding, or a popped internal fuse — the entire low-voltage system goes dead: no thermostat display, no contactor pull-in, and no heat-pump operation. This combo listing also covers the related 24V reversing-valve coil and barrier hardware (OEM 1176032, 1172619, 1173708) used on the same control assembly.

Compatibility

Direct OEM fit for the ICP/Heil/Tempstar WJH336000KTP0A2 heat-pump platform and related units using the 40VA 208/230-to-24V control transformer. Verify the part number and VA rating on your existing transformer before ordering.

Installation Guide

  1. Safety First — Disconnect power and verify zero voltage with a multimeter on both line and control terminals.
  2. Access — Remove the control-box service panel.
  3. Document — Photograph the primary (line) and secondary (24V) leads before disconnecting.
  4. Remove — Unscrew the transformer mounting bracket and disconnect the primary and secondary wiring.
  5. Install — Mount the new transformer, land the 208/230V primary and 24V secondary leads exactly per your photo.
  6. Test — Restore power, confirm 24V at the secondary, and verify the thermostat, contactor, and reversing valve energize.

Signs You Need a Replacement

  • No 24V control power — blank thermostat, system dead
  • Contactor or reversing valve will not energize
  • Transformer hums loudly, overheats, or smells burnt
  • Repeated blown low-voltage fuses tied to a shorted winding

Frequently Asked Questions

Does this Transformer fit my ICP WJH336000KTP0A2 — 208/230V to 24V | Ships Today?
Yes. This is the factory-specified OEM transformer for the ICP WJH336000KTP0A2 — 208/230V 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 WJH336000KTP0A2 — 208/230V 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.
How fast does National HVAC Parts ship?
