Heil Quaker ICP 1009385 Restrictor

The Heil Quaker ICP 1009385 Restrictor is a critical OEM replacement part designed for precise airflow management within residential and commercial furnace vent blower assemblies. Engineering this Vent Blower Restrictor "D" SK involves high-durability composite materials capable of withstanding the thermal cycles common in high-efficiency venting systems. By regulating the static pressure and exhaust velocity, the 1009385 ensures that the draft inducer motor operates within its intended performance curve, preventing combustion instability or pressure switch trips. This ICP furnace part is essential for maintaining the AFUE rating of the appliance and is cross-referenced with various legacy Heil, Tempstar, and Comfortmaker units, specifically models like the GUH075A012CIN and GUH075A012IL. For technicians performing maintenance, replacing a warped or missing blower restrictor plate is vital for protecting the long-term integrity of the secondary heat exchanger and ensuring consistent ignition sequences.

Key Benefits

• Enables precise airflow control to maintain proper combustion air-to-fuel ratios.
• Constructed from high-durability composite to resist heat-related deformation and chemical corrosion.
• Engineered specifically for Heil Quaker ICP equipment, ensuring correct internal fitment and clearance.
• Maintains venting system efficiency by optimizing exhaust gas velocity through the flue pipe.

Common Questions

Which specific models is the 1009385 restrictor compatible with?
This component is frequently used in ICP 80% and 90% AFUE furnaces, including specific model series such as GUH075A012CIN, GUH075A012IL, and GUH075A012IN. Always verify the parts list in the unit service manual.

What are the signs that a vent blower restrictor needs replacement?
Technicians should inspect the restrictor if the furnace experiences frequent pressure switch errors, soot buildup on burners, or visible heat damage near the vent blower housing. A damaged restrictor often leads to turbulent airflow and inefficient exhaust venting.

Is the 1009385 a direct replacement for older ICP part numbers?
Yes, this part regularly replaces legacy part numbers such as 2972011. It is designed to meet current OEM specifications for exact fit and function within the blower assembly.
