ICP Transformer for YH036GC — 40VA 24V Control | Ships Today

Overview

This OEM control transformer powers the 24V low-voltage circuit on the ICP Tempstar/Heil YH036GC heat pump system. Rated at 40VA with a 24V secondary, it supplies the contactor coil, reversing valve solenoid, relays, and thermostat. If the transformer fails, the entire control side loses power — the system will not respond to the thermostat, the contactor will not energize, and the unit produces no heating or cooling. Typical causes of failure are a shorted secondary, a blown internal thermal fuse from an overloaded control circuit, or insulation breakdown over time. OEM part numbers covered by this listing for the YH036GC control assembly include 34329055, 96467, and 1053004.

Specifications

Compatibility

Designed for the ICP Tempstar/Heil YH036GC and the matching Comfortmaker and Heil branded units sharing the same control platform. Confirm the existing transformer rating and terminal arrangement before installing.

Installation Guide

1. Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter at the control board.
2. Access — Remove the service panel to reach the control compartment.
3. Document — Photograph all primary and secondary wire connections before disconnecting.
4. Remove — Disconnect the line-voltage primary leads and 24V secondary leads, then unbolt the transformer from its bracket.
5. Install — Mount the new transformer and reconnect primary and secondary leads exactly per your photo.
6. Test — Restore power and confirm 24V across the secondary terminals and a normal thermostat call.

Signs You Need a Replacement

• No 24V control voltage; system unresponsive to the thermostat
• Contactor and reversing valve will not energize on a call
• Burnt smell or visibly scorched transformer housing
• Repeated control fuse failures after a low-voltage short
