Rheem-Ruud AP11941 Piezo Ignitor

For service technicians troubleshooting pilot issues on residential and commercial gas units, the Rheem-Ruud AP11941 Piezo Ignitor is the industry-standard OEM replacement part. This piezoelectric mechanism generates a high-voltage spark to ignite the pilot burner assembly without requiring an external power source or battery. Designed specifically for Rheem and Ruud gas water heaters, it features a rugged, high-temperature resistant housing built to withstand the rigorous conditions inside the burner chamber. As a genuine Rheem replacement part, it ensures precise fitment and eliminates the grounding issues common with universal aftermarket igniters. The push-button ignition interface allows for reliable, one-handed operation during the pilot lighting sequence, even on older standing pilot systems. Whether you are performing a routine maintenance call or a full burner assembly overhaul, using the AP11941 water heater igniter ensures your installation meets factory specifications for safe gas ignition and consistent technical performance across multiple HVACR and water heating platforms.

• OEM Compatibility: Engineered specifically for Rheem, Ruud, and Richmond gas-fired appliances to ensure a exact fit.
• No External Power Required: Utilizes piezoelectric crystal technology to generate a spark mechanically, ensuring operation during power outages.
• Durable Construction: Built with high-impact materials and heavy-duty internal components to resist heat-cycle fatigue.
• Direct Connection: Features standard slip-on terminals for a rapid, secure connection to the existing pilot electrode lead.

Why is my piezo ignitor not clicking or sparking?
This is usually caused by a cracked ceramic insulator on the electrode or a loose grounding wire. If the mechanical button clicks but no spark is visible at the pilot hood, the internal crystal may be depleted, requiring a full replacement of the AP11941.

Can this part be used on both Natural Gas and Propane (LP) units?
Yes, the Rheem-Ruud AP11941 is a mechanical spark generator and is independent of the fuel type. It is compatible with both NG and LP burner configurations.

Is the mounting bracket included with this igniter?
The AP11941 is the igniter module itself. It is designed to snap directly into the existing mounting bracket on the gas control valve or the water heater jacket.
