Overview

OEM parts 1172574 and 1173715 provide the 24-volt control power and reversing-valve coil supply for the ICP / Tempstar / Heil WCH5184GKA100 heat pump. This control component energizes the low-voltage circuit that drives the reversing valve, contactor, and defrost board, stepping line voltage down to a stable 24V at approximately 40VA. When the 24V supply fails, the reversing valve cannot switch the unit between heating and cooling and the system will not start, leaving the unit stuck in one mode or completely dead.

Frequently Asked Questions

Does this Transformer fit my ICP WCH5184GKA100 — 24V 40VA Heat Pump | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP WCH5184GKA100 — 24V 40VA Heat Pump | 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 WCH5184GKA100 — 24V 40VA Heat Pump | 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.
