Overview

This is a genuine OEM 24VAC control relay (part number L01H009, marked AG90-23242-024W) for the ICP / Tempstar / Heil SUP15M2301CIA package unit. The relay uses a 24-volt control coil from the low-voltage transformer circuit to switch a higher-load line component on and off — typically the blower or an auxiliary contactor. When the coil burns open or the contacts pit and stick, the affected load either won't energize or won't shut off, producing no-heat, no-cool, or continuous-fan symptoms. This factory part drops straight into the original relay position with the correct coil voltage and contact rating.

Compatibility

Built as the factory-correct 24VAC relay for the ICP / Tempstar / Heil SUP15M2301CIA and shared across related SUP15 series package units that use the same low-voltage control circuit. Verify the printed part number (L01H009 / AG90-23242-024W) and confirm a 24-volt coil before installing.

Installation Guide

  1. Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
  2. Access — Remove the control/service panel to reach the relay and low-voltage terminal board.
  3. Document — Photograph all coil and load wiring before disconnecting.
  4. Remove — Unplug the spade terminals and release the relay from its mounting clip or screws.
  5. Install — Snap the new relay into place and reconnect each wire to the matching terminal per your photo.
  6. Test — Restore power and confirm the relay clicks in on a call and the controlled load energizes correctly.

Signs You Need a Replacement

  • Blower or load fails to energize on a thermostat call.
  • Fan or component runs continuously and won't shut off.
  • Audible chattering or buzzing from the relay.

Frequently Asked Questions

Does this Transformer fit my ICP SUP15M2301CIA — OEM L01H009 | Ships Today?
Yes. This is the factory-specified OEM transformer for the ICP SUP15M2301CIA — OEM L01H009 | 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 SUP15M2301CIA — OEM L01H009 | 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.
