Overview

This OEM control and drive package for the ICP / Heil / Tempstar SUP23M2301DIA includes the 24VAC control relay (part L01H009, AG90-23242-024W) and the 1 HP 240VAC motor (part L06K005). The 24VAC relay is the switching component in the low-voltage control circuit — it takes a 24-volt signal from the thermostat or board and switches a higher-voltage load such as the motor or contactor on and off. When the relay's coil opens or its contacts pit and weld, the load either fails to energize or refuses to shut off, producing intermittent no-run or runs-constantly symptoms. The included 1 HP 240VAC motor provides the mechanical drive for the unit. Replacing a worn relay restores reliable, on-demand switching of the 24V control circuit.

Compatibility

Direct OEM fit for the ICP / Heil / Tempstar SUP23M2301DIA. The 24VAC relay and 1 HP 240VAC motor are used across ICP-family equipment, so these parts also service many comparable Heil, Tempstar, and Comfortmaker units. Confirm the relay coil is 24VAC and the motor is 1 HP / 240V before installing.

Installation Guide

Safety First — Disconnect power at the breaker and verify zero voltage at the relay and motor terminals with a multimeter.
Access — Remove the control-panel cover and motor access panel.
Document — Photograph all relay coil/contact terminals and motor leads before disconnecting.
Remove — Disconnect wiring, unbolt the old relay and, if servicing it, the motor, and lift them out.
Install — Mount the new relay and motor, then reconnect the 24V coil, switched load, and 240V motor leads exactly per your photo.
Test — Restore power and confirm the relay pulls in on a thermostat call and the motor starts and runs smoothly.

Signs You Need a Replacement

Frequently Asked Questions

Does this Transformer fit my ICP SUP23M2301DIA — OEM L01H009 | Ships Today?

Yes. This is the factory-specified OEM transformer for the ICP SUP23M2301DIA — 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 SUP23M2301DIA — 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.
