Overview

This OEM control transformer steps down line voltage to the 24V control circuit that powers the thermostat, contactor coil, gas valve, and control board on your ICP / Tempstar / Heil WPG3302040RKB1 system. It accepts a 208/230V primary input and delivers a regulated 24V, 40VA secondary output. When a transformer fails, the entire low-voltage control system goes dead: the thermostat screen goes blank, the contactor will not pull in, and the unit will not start at all. A buzzing transformer, a blown low-voltage fuse, or a burnt smell at the control box are classic failure signs. This listing includes the matching 24V barrier (OEM 1176032) and transformer (OEM 1173691).

Compatibility

Engineered as a direct OEM replacement for the ICP / Tempstar / Heil WPG3302040RKB1 package unit. The 208/230V-to-24V 40VA configuration is shared across many ICP-family condensers, package units, and furnaces, but always confirm the printed voltage and VA rating on your original transformer before installing.

Installation Guide

Safety First — Disconnect power at the breaker and disconnect switch, then verify zero voltage with a multimeter.
Access — Remove the control-box service panel.
Document — Photograph all primary and secondary wire connections before disconnecting.
Remove — Disconnect the primary (line) and secondary (24V) leads, then unbolt the transformer from the panel.
Install — Mount the new transformer, land the primary leads on the correct voltage tap, and reconnect the 24V secondary per your photo.
Test — Restore power and confirm 24V at the secondary and normal control operation.

Signs You Need a Replacement

Blank thermostat and completely dead low-voltage controls
Repeatedly blown 3- or 5-amp low-voltage fuse

Frequently Asked Questions

Does this Transformer fit my ICP WPG3302040RKB1 — 208/230V to 24V 40VA | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP WPG3302040RKB1 — 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 WPG3302040RKB1 — 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.
