What customers say
Consumers appreciate this ignitor for its immediate functionality, noting a perfect fit and easy installation that quickly revives furnaces. Many find significant value as a cost-effective DIY repair, saving money over professional service. However, the core sentiment is dominated by concerns over long-term reliability. A notable number of users report premature failure after only one or two seasons, contrasting sharply with original equipment expectations. While it serves excellently as an immediate, budget-friendly replacement, the recurring short lifespan tempers overall satisfaction, suggesting buyers should view this as a temporary solution rather than a permanent fix.
Know before you buy
This ignitor is designed to replace OEM models 632313, 632313C, 903110, and FC047. If your existing part matches these numbers or your furnace requires a 115-volt straight-style silicon nitride ignitor, this unit should be compatible.
Silicon nitride is highly durable and resistant to the extreme thermal cycling that causes ignitors to fail. It offers superior thermal conductivity, which ensures a faster and more consistent ignition for your gas furnace.
Yes, this ignitor is fully compatible with both natural gas and propane-fueled furnaces. It is engineered to perform reliably regardless of the fuel type used in your standard efficiency system.
Yes, 2¼ inches is a common length for many residential gas furnace ignitors. However, you should always measure your current ignitor to ensure the dimensions match, as even slight variations can affect the ignition process.
Installation typically requires basic hand tools, such as a screwdriver and a nut driver, to access the burner assembly. Because you are working with electrical components, ensure the power to your furnace is completely shut off before beginning the replacement.
