Nordyne 661104R Pilot Assembly

The Nordyne 661104R Pilot Assembly is a fundamental OEM replacement component for standing pilot ignition systems in specific furnace platforms. Engineered for versatility, this dual-fuel pilot assembly is designed for compatibility with both natural gas (NAT) and liquid propane (LP) applications. It features a factory-installed .013 orifice (part number 660922), which is critical for maintaining a stable and consistent pilot flame required for proper thermocouple heating and reliable burner ignition. This unit is the direct replacement for the legacy 660911 pilot burner, often found in older M1 series mobile home furnaces.

For field technicians, restoring system integrity means using the correct furnace pilot burner replacement to prevent common call-backs like pilot outages or weak flame signals. The 661104R is manufactured with durable metal construction to withstand the thermal stress of continuous operation. It integrates seamlessly into the original burner bracket, ensuring the flame remains precisely positioned to satisfy the safety circuit. When diagnosing Nordyne furnace ignition problems, replacing the entire assembly is often more effective than cleaning a fouled orifice to ensure long-term reliability in M1 series units.

Key Benefits

• OEM Direct Replacement: Guaranteed fit for Nordyne and Miller M1 series furnaces, replacing old part number 660911.
• Dual Fuel Compatibility: Specifically designed to handle natural gas or propane (LP) gas-fired equipment.
• Optimized Orifice Size: Pre-installed .013 orifice ensures the correct BTU input for a stable pilot flame.
• Durable Construction: Built to endure rigorous commercial and residential furnace environments.
• Reliable Ignition: Corrects issues related to pilot outages, weak flames, and thermocouple dropout.

Common Questions

Which furnace models use the 661104R pilot assembly?
This 661104R pilot assembly is primarily used in Nordyne, Miller, and Intertherm M1 series gas furnaces. It is also found in brands like Broan, Frigidaire, and Tappan that utilize the Nordyne platform.

Does this assembly include the orifice?
Yes, it comes with the .013 orifice (part number 660922) pre-installed. For technical field replacements requiring only the orifice, part number RS821-0135 is the compatible substitute.

Can I use this for a propane conversion?
While the assembly is compatible with NAT and LP gas, ensure your gas valve and main burner orifices are correctly sized for the specific fuel type as per the original equipment manufacturer's conversion instructions.
