Overview

This OEM transformer assembly is the 24V control power supply for the ICP / Tempstar / Heil WPA3422000RKB1 heat pump. It steps the incoming 208/230V line down to 24V to drive the contactor coil, reversing valve, and thermostat circuit. The kit centers on OEM part 1173691 (TRANS 208/230>24 40VA) and includes the 1176148 terminal barrier (BARRIER 24V 42-60) and the 1176137 24V DPDT relay (R8222B1232) used in the low-voltage control circuit. When the transformer fails the entire control circuit goes dead — no contactor pull-in, no compressor, and often a blank thermostat. Buzzing, a repeatedly blown low-voltage fuse, or scorched secondary terminals all point to replacement.

Compatibility

Direct-fit replacement for the ICP / Tempstar / Heil / Comfortmaker WPA3422000RKB1 condenser. The 208/230V-to-24V, 40VA transformer with barrier and DPDT relay is shared across many ICP-family split-system heat pumps of the same generation.

Installation Guide

Safety First — Disconnect power at the breaker and outdoor disconnect, then verify zero voltage with a multimeter on both primary leads.
Access — Remove the control-panel service cover on the condenser.
Document — Photograph every primary, secondary, and relay connection before disconnecting.
Remove — Label and disconnect the leads, then unbolt the old transformer, barrier, and relay from the bracket.
Install — Mount the new transformer, barrier, and relay, then reconnect all leads exactly per your photo.
Test — Restore power, confirm 24V across the secondary, and verify proper relay and contactor operation.

Signs You Need a Replacement

No 24V at the secondary — system completely unresponsive
Repeatedly blown low-voltage fuse
Loud buzzing or humming from the transformer
Scorched or melted secondary terminals, or a stuck control relay

Frequently Asked Questions

Does this Transformer fit my ICP WPA3422000RKB1 — 208/230V to 24V Kit | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP WPA3422000RKB1 — 208/230V to 24V Kit | 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 WPA3422000RKB1 — 208/230V to 24V Kit | 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.
