Overview

This is the OEM 40VA control transformer (part number 1173691), stepping 208/230V line voltage down to 24V, for the ICP / Tempstar / Heil WPA3302000RKB1 unit. It also covers the related control components for this model: the 24V barrier (1176144) and the 24V DPDT relay (R8222B1232, part 1176137). The transformer supplies the low-voltage power that runs the thermostat, control board, contactor coil, and relays. When it fails — usually from a shorted secondary or overload — the entire 24V control circuit goes dead and the system will not respond to the thermostat. A factory 40VA replacement restores reliable control power.

Compatibility

Factory replacement control transformer for the ICP / Tempstar / Heil WPA3302000RKB1 unit. Confirm the VA rating (40VA) and the primary (208/230V) and secondary (24V) voltages against your existing transformer before installing.

Installation Guide

Safety First — Disconnect power and verify zero voltage on both the line and 24V sides with a multimeter.
Access — Remove the control panel to reach the transformer and its leads.
Document — Photograph the primary tap selection (208 vs 230) and every secondary connection before disconnecting.
Remove — Disconnect the primary and secondary leads, then unbolt the old transformer from the panel.
Install — Mount the new transformer, match the primary tap to your supply voltage, and reconnect per your photo.
Test — Restore power and confirm 24V across the secondary and a normal response to a thermostat call.

Signs You Need a Replacement

No 24V control power; system completely unresponsive to the thermostat
Repeatedly blown low-voltage fuse or tripped breaker
Burnt smell, discoloration, or melted potting on the transformer

Frequently Asked Questions

Does this Transformer fit my ICP WPA3302000RKB1 — 208/230 to 24V OEM 1173691 | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP WPA3302000RKB1 — 208/230 to 24V OEM 1173691 | 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 WPA3302000RKB1 — 208/230 to 24V OEM 1173691 | 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.
