The Heil Quaker ICP 1170003 Transformer is a critical OEM replacement part for technicians servicing ICP, Tempstar, and Comfortmaker gas furnaces. This 120V to 24V step-down transformer provides a reliable 40VA power rating, ensuring the control circuit has the necessary amperage to drive gas valves, ignition modules, and fan timers without voltage drop. Built for high-duty cycle applications, its compact frame allows for direct integration into existing control panels, maintaining the electrical integrity of the HVAC low-voltage system.

When diagnosing furnace power issues or failed 24V control circuits, this 40VA class 2 transformer is the standard solution for 120V primary input configurations. It effectively replaces older part numbers including 612850, 1008782, and 1540352. Its durable construction is designed to withstand the thermal stressors found in modern high-efficiency heating systems, providing a stable 24-volt secondary output for consistent component sequencing.

Item is Non Cancelable / Non Returnable

• Direct OEM Compatibility: Engineered for seamless fitment in Heil Quaker and ICP family equipment.
• Robust 40VA Output: Supplies sufficient current for multi-component low-voltage circuits.
• Circuit Protection: Helps prevent control board damage by maintaining stable secondary voltage.
• Wide Application: Replaces multiple legacy part numbers (1170003, 612850, 4000Y01E07AE191).

What causes a 1170003 transformer to fail?
Most failures result from a short in the 24V secondary circuit, often caused by a grounded contactor coil or a pinched thermostat wire. Always check the secondary load before energizing a new HVAC transformer.

Can I use this 40VA transformer to replace a 30VA model?
Yes, you can upgrade from a lower VA rating to a higher one (like this 40VA unit), as it provides greater overhead for the control circuit. Never downsize the VA rating.

Is the 1170003 compatible with 208V or 240V systems?
No, this specific model is a 120V primary transformer. For 208/240V applications, a multi-tap or dedicated high-voltage primary unit is required.
