Overview

This OEM control transformer (part number 1172028) steps the incoming 208/230V line voltage down to the 24V control voltage that your ICP WAXT364A1 system uses to power thermostats, contactors, relays, and the control board. Rated at 40VA, it supplies enough capacity to drive the full low-voltage control circuit. When a transformer fails — often from a shorted control wire, a stuck contactor coil, or simple age-related winding breakdown — the entire system goes dead even though high-voltage power is present. A blown transformer is one of the most common no-cool/no-heat call causes, and replacing it restores 24V control power instantly.

Compatibility

Directly fits the ICP/Tempstar/Heil WAXT364A1 and other systems in the WAXT family that specify the 1172028 transformer. Always confirm your existing transformer is a 208/230V-to-24V 40VA unit before replacing.

Installation Guide

  1. Safety First — Disconnect power at the breaker and the unit disconnect, then verify zero voltage with a multimeter.
  2. Access — Remove the service panel to reach the control box.
  3. Document — Photograph all primary and secondary wires before disconnecting.
  4. Remove — Label and disconnect the line-voltage primary leads and the 24V secondary leads, then unbolt the old transformer from its bracket.
  5. Install — Mount the new transformer, reconnect primary and secondary leads per your photo, matching the 208/230V tap to your supply voltage.
  6. Test — Restore power and confirm 24V across the secondary terminals and proper system operation.

Signs You Need a Replacement

  • System completely unresponsive (no cooling or heating) despite line power present
  • No 24V reading across the secondary terminals
  • Repeatedly blown low-voltage fuse or burnt-smelling transformer
  • Visible scorching, melted potting, or a cracked transformer case

Frequently Asked Questions

Does this Transformer fit my ICP WAXT364A1 — 208/230V to 24V 40VA | Ships Today?
Yes. This is the factory-specified OEM transformer for the ICP WAXT364A1 — 208/230V to 24V 40VA | 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 WAXT364A1 — 208/230V to 24V 40VA | 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?
