Overview

This OEM 40VA control transformer (part number 1173691) steps 208/230V line voltage down to the 24V control voltage that powers the thermostat, relays, and contactor coil on your ICP WPA3242000RKB1 unit. This listing also covers the companion low-voltage components in the control circuit: the 24V DPDT relay (1176137, Honeywell R8222B1232) and the 24V terminal barrier/insulator (1176144). When a transformer fails, the entire 24V control circuit goes dead — the thermostat screen blanks, the contactor never pulls in, and the system simply won't respond to a call. A buzzing transformer, a tripped low-voltage circuit, or a melted/shorted secondary are classic indicators. A correctly rated 40VA OEM transformer restores stable control power and protects downstream components.

Compatibility

Direct OEM replacement for the 208/230V-to-24V 40VA control transformer in the ICP/Heil/Tempstar/Comfortmaker WPA3242000RKB1 and related condensing units. Confirm your primary voltage (208/230V), secondary voltage (24V), and VA rating match before installing, as undersizing the VA can overload and burn out a new transformer.

Installation Guide

Safety First — Disconnect all power and verify zero voltage with a multimeter on both the primary and secondary leads.
Access — Remove the control/service panel to reach the transformer and relay.
Document — Photograph the primary (line) and secondary (24V) wiring before disconnecting.
Remove — Disconnect the primary and secondary leads, then unbolt the failed transformer from the panel.
Install — Mount the new transformer, land the primary on the correct 208/230V tap, and reconnect the 24V secondary per your photo.
Test — Restore power and confirm a steady ~24V across the secondary and that the control circuit energizes on a call.

Signs You Need a Replacement

Dead thermostat and no 24V control power
System won't respond to a call for heat or cool
Buzzing, humming, or overheated transformer
Repeatedly blown low-voltage fuse or burnt secondary

Frequently Asked Questions

Does this Transformer fit my ICP WPA3242000RKB1 — 40VA 208/230V to 24V | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP WPA3242000RKB1 — 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 WPA3242000RKB1 — 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.
