Overview

This OEM 40VA control transformer is the low-voltage power supply for the ICP WPG3244060LKC1 packaged gas/electric unit. It steps the 208/230V line voltage down to the 24V control circuit that powers the thermostat, ignition control, contactor coil, and relays. When a transformer fails, the entire 24V control side goes dead — the unit will not respond to a thermostat call even though line voltage is present. Common failure modes include an open primary or secondary winding (no 24V output), an internal short that repeatedly blows the control fuse, or burned/overheated windings caused by a shorted contactor coil downstream. This assembly includes the 24V barrier (OEM 1178431) and the 40VA transformer (OEM 1173691).

Compatibility

Engineered as a direct-fit replacement for the ICP WPG3244060LKC1 and the family of ICP, Tempstar, Heil, and Comfortmaker packaged units that share this 40VA control transformer. Always confirm the primary tap matches your incoming line voltage (208V vs 230V) before wiring.

Installation Guide

Safety First — Disconnect power at the unit disconnect and breaker, then verify zero voltage with a multimeter on both line and 24V terminals.
Access — Remove the control-panel service panel to expose the transformer.
Document — Photograph all primary and secondary wire connections before disconnecting.
Remove — Label and disconnect the primary (208/230V) and secondary (24V) leads, then unbolt the transformer and barrier from the bracket.
Install — Mount the new transformer and barrier, then reconnect the matching primary tap and the 24V secondary per your photo.
Test — Restore power and confirm 24V across the secondary with a meter before initiating a heat or cool call.

Signs You Need a Replacement

No 24V at the control board even with line voltage present.
Thermostat is blank or the unit ignores all calls for heat/cool.
Control fuse blows immediately on power-up.
Transformer is hot to the touch, buzzing, or shows scorched/melted housing.

Frequently Asked Questions

Does this Transformer fit my ICP WPG3244060LKC1 — 40VA 208/230V to 24V | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP WPG3244060LKC1 — 40VA 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 WPG3244060LKC1 — 40VA 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.
