Overview

This OEM 24-volt control component (parts #1172619 / #1175367 / #1190263) supplies the low-voltage control power for the ICP/Tempstar/Heil RHS120S0BA0AAA heat pump. The 24V control circuit energizes the contactor coil, reversing valve solenoid, and defrost board — every command the thermostat sends rides on this 24V supply. When control power is lost, the entire system goes dead even though high-voltage power is present at the unit. Rated at 24 volts with 40VA of control capacity, this is the correct factory-spec part for this model.

Frequently Asked Questions

Does this Transformer fit my ICP RHS120S0BA0AAA — 40VA Control Power | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP RHS120S0BA0AAA — 40VA Control Power | 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 RHS120S0BA0AAA — 40VA Control Power | 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.
