Overview

This 40VA, 24V control transformer supplies the low-voltage power that drives the control circuit, reversing valve coil, and relays in your ICP RHS183S0CA0AAAA heat pump. Bundled with it are the OEM reversing valve coil (1172619, 24V) and DPST control relay (1178205, T92P7A22-24) so the entire 24V control chain stays factory-matched. When a transformer fails, the thermostat goes dark, the contactor won't pull in, and the unit simply won't respond to a call for heating or cooling.

Frequently Asked Questions

Does this Transformer fit my ICP RHS183S0CA0AAAA — Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP RHS183S0CA0AAAA — 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 RHS183S0CA0AAAA — 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.
