The Heil Quaker ICP 1000742 Relay is a specialized DPST (Double Pole Single Throw) combination system relay designed for precise 24V control circuit switching in residential and light commercial HVAC applications. Engineered as an OEM replacement part, this switching relay manages high-current blower motors and furnace components, ensuring reliable contact closure across the normally open poles. This Heil Quaker potential relay is vital for restoring proper staging and voltage distribution within the control board HVAC wiring diagram. For service technicians, the 1000742 provides a robust solution for troubleshooting intermittent electrical failures or burned-out contacts. It is fully compatible with diverse ICP (International Comfort Products) furnace models, including those under the Comfortmaker and Tempstar brands. Utilizing 24V coil voltage, this component ensures efficient signal processing between the thermostat and the load, maintaining system integrity under high-cycle operations in demanding environments.

• DPST Configuration: Provides simultaneous control of two independent circuits, essential for HVAC multi-stage operation.
• OEM Compatibility: Exact replacement for ICP 1000742, eliminating the need for mounting bracket modifications or field-shaving terminals.
• Industrial Build Quality: Built to withstand the thermal stressors found in furnace cabinets and air handler enclosures.
• Simplified Integration: Standard terminal labeling facilitates rapid control relay replacement and reduces diagnostic time.

What are the coil voltage requirements for this relay?
The ICP 1000742 operates on a standard 24VAC control circuit, making it compatible with most modern HVAC transformers and thermostats.

Can this relay replace a SPST relay in the field?
While a Double Pole Single Throw relay can technically handle a single circuit, load ratings and mounting footprints must be verified against the original equipment specifications to ensure safety.

Is this relay compatible with non-Heil Quaker units?
Yes, as long as the DPST switching logic and electrical ratings align, this relay is frequently utilized across various Tempstar, Arcoaire, and Comfortmaker furnace parts directories.
