The Hot Surface Igniter on Your A. O. Smith Boiler
The hot surface igniter (HSI) is a silicon-nitride or silicon-carbide element that heats until it glows, igniting the gas at the burner. HSIs are fragile and degrade with each cycle; a cracked igniter is a very common no-heat cause.
On A. O. Smith systems — including models such as ProLine, Signature, Voltex — a failing hot surface igniter often shows up as no hot water or related symptoms. We diagnose it precisely and install the correct genuine A. O. Smith part.
