When your furnace isn't igniting properly, this upgraded hot surface ignitor could be the straightforward fix you need. This universal silicon nitride ignitor replaces several part numbers including 903110, 903110A, 632504, 632313, 632313C, and FC047, making it compatible with a wide range of Nordyne furnace models. The specifications are solid - it operates at 115V ± 10%-15% (so between 98V-127V), has a cold resistance of 8-16Ω, and reaches temperatures up to 1180°C for reliable ignition. Compatibility is key here - this works with Nordyne gas furnace models starting with M1/Mg1E units like M1MA056, M1MB070, M1MC077, M1MD090, and various M2 series models. The silicon nitride construction is what really makes this ignitor stand out - it heats up quickly, withstands extreme temperatures beautifully, and provides consistent performance season after season. Installation is about as simple as it gets for furnace repairs - it comes with the plug already attached, so you're basically just unplugging the old one and plugging in the new one (after turning off power, of course!). The improved energy efficiency is a nice bonus too - by providing a consistent ignition source, your furnace burns fuel more completely, which can actually save you money on heating bills over time. Whether you're a DIY homeowner or a professional HVAC technician, this ignitor delivers reliable performance that gets your furnace firing up properly without the high cost of a service call.
