Overview

This genuine OEM control transformer (OEM 1173691) steps down 208/230V line voltage to the 24V needed to power the thermostat, contactor coil, and low-voltage control circuit on the ICP / Tempstar / Heil WPA3364000RKC1 heat pump. Rated at 40VA, it supplies stable control power to every 24V component in the system and includes the OEM 1176144 24V terminal barrier for safe, organized low-voltage connections. When a transformer fails, the entire control circuit goes dead — the thermostat blanks out and the unit won't respond to any call — so a working transformer is essential to system operation.

Frequently Asked Questions

Does this Transformer fit my ICP WPA3364000RKC1 — 208/230V to 24V | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP WPA3364000RKC1 — 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 WPA3364000RKC1 — 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.
