International Comfort Products 1054395 Restrictor Plate for HVAC Furnace Systems

The International Comfort Products 1054395 Restrictor Plate is a critical component designed to optimize the performance and efficiency of residential and light commercial HVAC furnace systems. This genuine OEM replacement part plays a vital role in controlling airflow and maintaining proper system operation.

Key Functions:

• Controls draft pressure in the exhaust blower or inducer assembly to prevent excessive heat loss
• Ensures proper combustion air velocity reaches the burner for optimal efficiency
• Maintains correct negative pressure so the pressure switch can detect proper furnace operation
• Prevents the inducer motor from over-drafting and operating outside its intended performance curve
• Helps achieve even temperature distribution and maximum combustion efficiency

This restrictor plate typically installs at the inlet of the exhaust blower assembly and is particularly important for certain furnace configurations, including systems with shorter vent runs or specific BTU ratings. The plate creates a controlled pressure drop that ensures the inducer motor operates within its design parameters, protecting the motor from overheating while maintaining safe and efficient furnace operation.

Compatibility: Designed for International Comfort Products furnace systems and compatible with related brands including Heil, Tempstar, Comfortmaker, Arcoaire, and KeepRite units. When replacing an exhaust blower or inducer motor, it's essential to transfer the restrictor plate from the old assembly to the new one to maintain proper furnace performance.
