Overview

This OEM 24V control transformer/coil component covers the low-voltage control supply for the ICP/Tempstar/Heil RHS048L0BB0AAAA heat pump and includes the matching 24V coils (parts 1172619 and 1175367). It delivers the 24V power that energizes the contactor coil, reversing-valve solenoid, and thermostat circuit. When this component fails, the low-voltage side goes dead — a blank thermostat, an unresponsive contactor, and a heat pump that ignores the call for heating or cooling. Typical failures include an open winding, an internal short from overload, or damage caused by a shorted control wire. Installing the correct 24V / 40VA OEM replacement restores reliable control power and proper reversing-valve switching.

Document — Photograph all primary and secondary wiring before disconnecting.
Remove — Label leads, disconnect them, and unfasten the old component.
Install — Mount the new unit and reconnect each lead to the matching terminal per your photo.
Test — Restore power, confirm 24V on the secondary, and verify normal heat/cool switching.

Frequently Asked Questions

Does this Transformer fit my ICP RHS048L0BB0AAAA — 24V 40VA Control | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP RHS048L0BB0AAAA — 24V 40VA Control | 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 RHS048L0BB0AAAA — 24V 40VA Control | 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.
