Wayne 31812-003 Ignitor

For industrial heating and high-pressure wash systems, the Wayne 31812-003 Ignitor is a critical 12V DC component engineered for constant-duty performance. This solid-state 12V burner ignitor is specifically matched for Wayne W/M series burners but serves as a versatile replacement across various gas-engine-powered pressure washers. With an input rating of 12V DC at 4.8 amps, the unit delivers a reliable 14,000V (20KV peak) output at 30 mA, ensuring a high-energy spark for consistent combustion in demanding field environments. Designed for efficiency, the 31812-003 electronic ignitor utilizes a bottom-mount configuration for secure housing integration. As an OEM burner part, it ensures precise timing and compatibility with original electrode spacing. Whether you are performing a routine service or a total ignition overhaul, this 12V ignition transformer provides the voltage stability needed to prevent lockout and maintain thermal efficiency in commercial-grade heating assemblies.

• Universal Compatibility: Seamlessly integrates with the Wayne M-Series and W-Series chassis, as well as multiple mobile pressure washer platforms.
• Solid-State Reliability: Advanced solid-state circuitry offers a more consistent spark than traditional copper-core transformers, reducing fuel soot accumulation.
• Constant Duty Cycle: Engineered to handle high-frequency firing without thermal degradation, ideal for continuous-run heating applications.
• High-Voltage Output: Generates a 20KV peak discharge to bridge electrode gaps even in high-moisture or cold-weather environments.
• Rugged Housing: The bottom-mount sealed casing protects interior electronics from the vibration and heat typical of burner compartments.

Is the 31812-003 compatible with 120V burner systems?
No, this is a 12V DC-only ignitor. Installing this on a 120V AC circuit will result in immediate failure of the internal solid-state components.

What are the signs that my Wayne ignitor needs replacement?
Typical failure indicators include a weak blue or orange spark instead of a crisp white arc, delayed ignition resulting in "popping," or the burner motor running without the ignitor firing, leading to system lockout.

Does this unit include the mounting bracket?
This specific model features a bottom-mount configuration. Always verify your existing bracket alignment to ensure the springs make solid contact with the electrode tabs.
