The Heil Quaker ICP 1174663 is a heavy-duty 30AMP 24V Coil Power Relay engineered for heavy-cycle switching in commercial and residential HVACR applications. As a genuine ICP OEM replacement part, this SPST relay (Single Pole Single Throw) provides the exact electromagnetic switching required to govern blower motors and high-amperage loads without the risk of arcing or chatter. Standardized for 24V control circuits, the 1174663 ensures seamless communication between the thermostat and the high-voltage components of the system. Designed specifically for International Comfort Products equipment, it fits a wide range of sub-brands including Heil, Tempstar, Comfortmaker, and Keeprite. Replacing a failing relay with this high-rating 30-amp component restores reliable circuit closure, preventing common furnace and AC blower failures. Technicians trust this factory-spec relay to maintain the original performance and safety protocols of the HVAC unit while providing a direct drop-in installation for field repairs.

• 30AMP Heavy-Duty Rating: Robust contact capacity allows for safe management of high-draw furnace blowers and compressor components.
• Precise 24V Coil Operation: Engineered for tight tolerances within low-voltage control systems to ensure immediate and reliable circuit engagement.
• OEM Compatibility: Guaranteed fit for ICP, Heil Quaker, and Tempstar units, eliminating the need for complex mounting modifications or terminal re-pinning.
• SPST Configuration: Simplifies the electrical path for efficient Single Pole Single Throw logic, reducing potential failure points in the wiring.

What are the symptoms of a failing ICP 1174663 relay?
Technicians typically observe a blower motor that fails to start despite receiving a 24V call, or a relay that "chatters" or stays "stuck closed," causing the fan to run continuously even when the thermostat is satisfied.

Can I use a universal 30A relay instead of the 1174663?
While universal relays may match the amperage, the 1174663 is the specific Heil Quaker power relay designed with the exact mounting footprint and terminal layout required for a secure, code-compliant fit inside the control cabinet.

Is this relay used for heating or cooling?
This HVAC power relay is versatile and used across both heating and cooling platforms, primarily to energized blower motors (indoor fans) and heat strip sequencers in electric furnaces or heat pumps.
