Ruud 62-24164-03 Direct Spark Ignitor Gas Furnace

Product Description

The RUUD 62-24164-03 is a direct spark ignitor (DSI) designed as an OEM-style replacement for RUUD and Protech gas furnace applications. This ignitor initiates combustion by generating a high-voltage spark directly at the burner, eliminating the need for a separate hot surface element. It is a critical ignition system component used in natural gas and LP furnace installations. Weighing 0.18 pounds and measuring 5.45 inches in length, 3.1 inches in width, and 2.1 inches in height, the part is compact and purpose-built for the furnace models listed in this product family. Licensed HVAC technicians perform this type of replacement during routine ignition system service or no-heat diagnostics.

This ignitor is specified for use in RUUD residential gas furnace models in the R801 and R802 series with the MSA designation. These include single-stage and multi-stage upflow and horizontal furnace configurations. Typical installation scenarios include replacing a failed or cracked ignitor during a no-heat service call or as part of a planned preventive maintenance inspection. The part is direct spark type, meaning the control board sends voltage directly to the ignitor electrode to fire the burner without a separate spark module in most configurations.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local mechanical codes and the furnace manufacturer service documentation. Always shut off electrical power and close the gas supply valve before removing or installing ignition components. Inspect the ignitor electrode for proper gap alignment and secure mounting after installation. Do not handle the electrode tip with bare hands, as skin oils can affect ignitor performance and service life.
