Overview

This OEM 24-volt control transformer powers the low-voltage control circuit on the ICP RHS102S0BA0AAAA heat pump. It steps line voltage down to the 24V needed to drive the thermostat, contactor coil, reversing valve coil, and control relays (related OEM control components include reversing valve coil PN 1172619, relay PN 1178205, and reversing valve assemblies PN 1175367 / 1190263). When the transformer fails, the entire control circuit loses power — the thermostat goes blank and nothing in the system energizes. Common failure symptoms include a dead thermostat, no 24V at the control board, a tripped or blown low-voltage fuse, a burnt-smelling or visibly scorched transformer, and an outdoor unit that will not respond to any call.

Frequently Asked Questions

Does this Transformer fit my ICP RHS102S0BA0AAAA — 40VA Control | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP RHS102S0BA0AAAA — 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 RHS102S0BA0AAAA — 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.
