Rheem-Ruud 62-24164-01 Spark Ignitor

The Rheem-Ruud 62-24164-01 Spark Ignitor is a mission-critical Direct Spark Ignition (DSI) component engineered for high-demand gas-fired equipment. This OEM furnace igniter features a durable Kanthal D heating element, a ferritic iron-chromium-aluminium alloy capable of withstanding combustion temperatures up to 2370°F. Designed with a 2-1/8 inch depth from the mounting flange to the tip and a 35-inch lead wire terminated with a 0.084-inch round pin, it ensures precise placement within the burner assembly. Pro-grade specs include a 1/8-inch spark gap, a 135-degree ground electrode offset, and an 83-degree spark electrode angle for optimized arc delivery. This assembly provides reliable ignition and functions as a flame sensor through flame rectification, preventing main burner firing if a pilot flame is not detected. This unit is the direct replacement for Rheem, Ruud, and WeatherKing gas furnace parts requiring the 62-24164-01 specification, ensuring seamless integration into your HVAC ignition system without field modifications.

• Precise OEM Fit: Drop-in replacement for Rheem and Ruud units, featuring a 35-inch high-temperature lead wire and standard 2.125-inch reach.
• Dual-Function Technology: Acts as both direct spark ignitor and flame sensing rod to ensure safe furnace sequences.
• Superior Material Grade: Kanthal D element construction offers high-cycle durability and resistance to oxidation in corrosive combustion environments.
• Accurate Arc Delivery: Factory-set 1/8-inch spark gap and specifically angled electrodes reduce nuisance ignition failures and HVAC error codes.

What are the signs that my DSI ignitor needs replacement?
Technicians typically look for cracked ceramic insulators, soot buildup on the electrodes, or a "clicking" sound without actual arc formation, which often indicates an internal short or continuity failure.

Can this ignitor be used in both vertical and horizontal furnaces?
Yes, provided the furnace's parts manual specifies the 62-24164-01 part number. The 35-inch wire length provides sufficient slack for various mounting orientations found in Rheem/Ruud air handlers and package units.

Does this part involve flame sensing?
Correct. This direct spark ignition assembly creates the initial arc and then remains in the flame path to provide the microamp signal back to the integrated furnace control board (IFC).
