Overview

This OEM 24V control transformer supplies low-voltage power to the 24V control circuit of your ICP (International Comfort Products) RHH102S0AA0AAAA heat pump. Rated at 40VA, it steps line voltage down to the 24V secondary that energizes contactors, reversing valve coils, control boards, and the thermostat circuit. When a transformer fails, the entire low-voltage control side goes dead — no thermostat response, no contactor pull-in, and no compressor or fan operation. Replacing it with the correct OEM-rated 40VA unit restores reliable 24V control power. Related OEM control components on this unit include reversing valve coil 1172619 and reversing valve assembly 1175367.

Frequently Asked Questions

Does this Transformer fit my ICP RHH102S0AA0AAAA — 24V Control Output | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP RHH102S0AA0AAAA — 24V Control Output | 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 RHH102S0AA0AAAA — 24V Control Output | 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.
