Overview

This OEM 24V control transformer is the dedicated low-voltage power source for the ICP/Tempstar/Heil RHS090H0CB0AAA heat pump. It steps the 208/240V line-voltage supply down to the 24V control circuit that powers the contactor coil, reversing valve solenoid, defrost board, and thermostat. Rated at 40VA, it delivers stable current to every low-voltage accessory on the unit. When a transformer fails, the entire control circuit goes dead — the contactor will not pull in, the compressor and condenser fan will not start, and the thermostat display may go blank. Common failure causes include a shorted secondary, a seized solenoid drawing excess current, or simple coil burnout from age and heat.

Compatibility

Engineered as a direct-fit replacement for the ICP/Tempstar/Heil RHS090H0CB0AAA heat pump and the broader RHS090 series sharing the same 24V control architecture. Always confirm the secondary voltage and VA rating against your existing transformer before installing.

Installation Guide

Safety First — Disconnect power at the breaker and the unit disconnect, then verify zero voltage with a multimeter.
Access — Remove the control-panel service cover to expose the transformer.
Document — Photograph all primary and secondary wire connections before disconnecting anything.
Remove — Label and disconnect the leads, then unbolt the failed transformer from its mounting bracket.
Install — Mount the new transformer, reconnect the primary and secondary leads exactly per your photo.
Test — Restore power and confirm 24V across the secondary, then verify the contactor pulls in on a call for cooling.

Signs You Need a Replacement

No 24V reading across the secondary terminals
Contactor will not energize and the system stays dead on a thermostat call
Blank or unresponsive thermostat with line power present
Burnt smell, scorching, or a tripped low-voltage fuse at the board

Frequently Asked Questions

Does this Transformer fit my ICP RHS090H0CB0AAA — 24V Control Circuit | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP RHS090H0CB0AAA — 24V Control Circuit | 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 RHS090H0CB0AAA — 24V Control Circuit | 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.
