Overview

This OEM 24V low-voltage control package for the ICP RYMA10F001 heat pump includes the core components that power and switch the unit's control circuit: the 24V reversing valve coil (part 34329055), a 24V 3PDT relay (part 1065280), and a 24V SPDT relay (part 1058148). These components operate off the system's 40VA control transformer circuit and are responsible for energizing the reversing valve and switching the contactor and accessory loads. A weak 24V circuit or a failed coil or relay shows up as a heat pump that won't change between heating and cooling, contactors that won't pull in, or repeated low-voltage faults. Genuine OEM parts deliver the correct coil resistance and contact ratings for dependable switching.

Frequently Asked Questions

Does this Transformer fit my ICP RYMA10F001 — 24V Heat Pump | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP RYMA10F001 — 24V Heat Pump | 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 RYMA10F001 — 24V Heat Pump | 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.
