Overview

This OEM control transformer (part #1173691) supplies the low-voltage 24V control circuit on your ICP/Tempstar/Heil WTA3482000RKA1 system. It steps down 208/230V line power to 24V at 40VA, powering the contactor coil, thermostat, and control board. When a transformer fails — typically from a shorted secondary, overload, or age — the entire control circuit goes dead: the contactor will not pull in, the blower and compressor will not start, and the thermostat display may go blank. A 40VA Class 2 rating provides ample headroom for standard residential control loads.

Compatibility

Designed as a direct OEM replacement for the ICP/Tempstar/Heil WTA3482000RKA1 condensing unit. Also commonly used across ICP-family equipment requiring a 208/230V-to-24V 40VA control transformer. Always verify the existing transformer's primary and secondary voltage and VA rating against your unit before installing.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
Access — Remove the control panel access cover.
Document — Photograph all primary and secondary wire connections before disconnecting.
Remove — Label and disconnect the primary (line) and secondary (24V) leads, then unbolt the old transformer from the mounting bracket.
Install — Mount the new transformer, match the primary leads to incoming line voltage and the secondary leads to the 24V circuit per your photo.
Test — Restore power and confirm 24V across the secondary; verify the contactor energizes on a call for cooling.

Signs You Need a Replacement

No 24V at the control board or thermostat — system completely unresponsive
Contactor will not pull in on a cooling call
Repeatedly blown low-voltage fuse or visible burnt/melted transformer housing

Frequently Asked Questions

Does this Transformer fit my ICP WTA3482000RKA1 — 208/230V to 24V | Ships Today?

How do I replace the transformer on my ICP WTA3482000RKA1 — 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.
