Nordyne 155314R Inducer Orifice

The Nordyne 155314R Inducer Orifice is a critical combustion component specifically engineered for 60,000 BTU gas-fired furnaces, including the widely serviced Nordyne M1 Series. This OEM restrictor orifice features a 1.063-inch internal diameter and a 2.5-inch outer diameter, designed to manage precise airflow regulation within the inducer assembly. For technicians troubleshooting systems that run hot or trip limit switches, replacing a compromised 155314R ensures the air-to-fuel ratio remains within manufacturer specifications for optimal combustion efficiency. Constructed from high-durability metal, it maintains proper manifold pressure and system static, preventing premature wear on the furnace booster. This genuine HVAC replacement part is essential for maintaining the reliable ignition performance required in residential and RV heating applications. Before installation, confirm the BTU rating and furnace model compatibility to ensure the induction process meets the static pressure requirements of the existing heat exchanger.

Key Benefits:

• Precise Gas Flow Regulation: Ensures an exact air-to-fuel ratio for efficient thermal transfer in 60K BTU units.
• OEM Compatibility: Exact replacement for Nordyne 155314, fitting M1 Series gas-fired furnaces and RV boosters.
• System Protection: Helps prevent high-limit switch tripping by maintaining correct venting static pressure.
• Industrial-Grade Build: Precision-machined metal construction resists heat-cycling fatigue and corrosion.
• Enhanced Ignition: Promotes consistent burner startup and minimizes combustion system vibration.

Common Questions:

What are the symptoms of a failing inducer orifice?
A blocked or warped orifice can lead to poor combustion, frequent limit switch trips, or "rumbling" during the ignition cycle due to improper airflow regulation.

Does this orifice fit all Nordyne 60K BTU furnaces?
While designed for many 60K BTU models, always verify the part number in your service manual, as specific inducer assembly configurations may vary by series.

Can I use a larger diameter orifice to increase heat?
No. Using an orifice with the wrong internal diameter will void safe operating parameters, risk CO production, and potentially damage the heat exchanger.
