Common Questions

Is the gas orifice pre-installed for LP or Natural Gas?
The Nordyne 903426 typically comes setup for natural gas from the factory. However, it includes the necessary hardware for LP conversion, which must be performed by a licensed technician during installation to ensure proper manifold pressure.

Will this burner assembly fix my furnace's "no-ignition" lockout?
If the diagnostic code indicates a burner or flame sensing issue and the existing burner shows signs of heavy scaling or clogged ports, replacing the gas burner assembly is the standard solution to restore reliable ignition.

Can I use this in an Intertherm or Miller furnace?
Yes, because Nordyne is the parent company for Intertherm and Miller, this part is frequently compatible with those brands. Always verify the specific model number on the furnace data plate before installation.
