Overview

This OEM 24-volt control transformer provides low-voltage power for the ICP Tempstar Heil RHS090L0BA0AAAA heat pump. It converts incoming line voltage to a stable 40VA, 24VAC output that energizes the thermostat, contactor coil, reversing-valve solenoid, and defrost control. A bad transformer typically presents as a fully dead system — no thermostat display, no contactor pull-in, and no outdoor unit operation. Built to OEM specification, it mounts in the original location and restores full control-circuit power. Related low-voltage components on this model include reversing-valve coil 1172619, relay 1178205, and reversing valve assemblies 1175367 and 1190263.

Frequently Asked Questions

Does this Transformer fit my ICP RHS090L0BA0AAAA — 40VA Class 2 | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP RHS090L0BA0AAAA — 40VA Class 2 | 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 RHS090L0BA0AAAA — 40VA Class 2 | 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.
