Nordyne 155315R Inducer Orifice

The Nordyne 155315R Inducer Orifice is a critical combustion component specifically engineered for 80,000 BTU gas furnaces. This OEM replacement part is essential for maintaining the correct exhaust gas velocity and ensuring the induced draft motor operates within the designed static pressure parameters. When troubleshooting pressure switch lockout or incomplete combustion issues, technicians must verify the integrity of the combustion blower orifice. A damaged or incorrect orifice can lead to flame rollout or poor venting performance in intermittent pilot and direct spark ignition systems. Designed for precise fitment in M1 series furnaces and various gas-fired heating units, this restrictor plate ensures the air-fuel ratio remains consistent with manufacturer specifications. Relying on genuine Nordyne furnace parts prevents premature venter motor failure and maintains the AFUE rating of the appliance during high-demand heating cycles.

• OEM Compatibility: Precision-engineered for 80K BTU Nordyne furnaces, ensuring seamless integration with existing draft inducer assemblies.
• Combustion Stability: Maintains the specific venturi effect required for proper exhaust scavenging and reliable pressure switch closure.
• Durable Construction: Fabricated from high-grade materials to withstand constant thermal cycling and exposure to flue gas condensates.
• Easy Installation: Standard configuration allows for rapid field replacement during emergency furnace repair calls.

How do I know if the inducer orifice needs replacement?
Inspect the orifice for signs of corrosion, warping, or soot accumulation that restricts airflow. If the pressure switch fails to close despite a functional inducer motor, the orifice clearance should be verified.

Will this orifice work on 100K BTU or 60K BTU models?
No, this specific part is calibrated for 80,000 BTU gas-fired units. Using an incorrectly sized restrictor will result in combustion instability and potential safety hazards.

Does this part include the mounting screws?
This listing is for the inducer orifice plate specifically; technicians should retain original hardware or utilize standard HVAC sheet metal screws for secure attachment to the housing.
