Overview

This OEM control transformer steps the incoming 208/230V line voltage down to the 24V low-voltage power that drives the thermostat, contactor coil, control board, and safety circuits on your ICP WPG3482130LKB1 system. Rated at 40VA, it delivers enough current to energize several 24V loads at once. The kit includes part 1173691 (TRANS 208/230>24 40VA) and the 1176032 24V barrier. A failed transformer is among the most common causes of a totally dead control circuit: the thermostat goes blank and the blower and compressor will not energize even though line power is present. Typical failures include an open primary or secondary winding, a shorted winding that blows the low-voltage fuse, or a unit burned out by a downstream 24V short.

Compatibility

Engineered for the ICP / Tempstar / Heil / Comfortmaker WPG3482130LKB1 and other units in the same family using a 40VA, 208/230V to 24V control transformer. Verify your existing transformer's VA rating and primary/secondary voltages before ordering.

Installation Guide

Safety First - Disconnect power at the breaker/disconnect and verify zero voltage with a multimeter before touching any wiring.
Access - Remove the service panel to reach the control compartment.
Document - Photograph all primary and secondary wire connections before disconnecting.
Remove - Label and disconnect the primary and secondary leads, then unbolt the old transformer from its bracket.
Install - Mount the new transformer, reconnect the primary to line voltage and the secondary to the 24V circuit per your photo, and install the 24V barrier.
Test - Restore power and confirm 24V at the secondary plus normal thermostat and contactor operation.

Signs You Need a Replacement

Thermostat is blank and the entire 24V control circuit is dead
No voltage at the secondary terminals with line voltage present
Blower and compressor will not energize on a heat or cool call
Repeated blown low-voltage fuses or a burned/smelling transformer

Frequently Asked Questions

Does this Transformer fit my ICP WPG3482130LKB1 - 40VA 208/230V to 24V | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP WPG3482130LKB1 - 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 WPG3482130LKB1 - 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.
