Lochinvar & A.O. Smith 100108711 Heating Element

As a genuine OEM replacement part, the Lochinvar & A.O. Smith 100108711 Heating Element is a critical component for maintaining the thermal efficiency of residential electric water heaters. This 1650W 120V heating element features a 5.5-inch copper sheath, designed for rapid heat transfer and long-term durability in standard water conditions. Built with a universal flange, it ensures a secure, leak-free fit during water heater element replacement in compatible Lochinvar and A.O. Smith models like the EJC6, EJC10, and ProMax series. In the field, you will recognize this as the direct replacement for part number 9002072005. Its compact 5.5-inch length makes it specifically suited for smaller tank profiles where standard elements might interfere with the internal tank structure. When diagnosing a system that is tripping the circuit breaker or failing to reach the setpoint temperature, this element provides the 1.65 kW output required to restore recovery rates to factory specifications without risk of impedance mismatch with original control boards.

Key Benefits

• Direct OEM Compatibility: Engineered as a genuine 100108711 element to ensure precise fitment and electrical synchronization with A.O. Smith and Lochinvar systems.
• Copper Sheath Construction: Utilizes high-grade copper heating element material for superior thermal conductivity and resistance to scale buildup in residential applications.
• Universal Flange Design: Simplifies the HVAC installation process by providing a standard mounting interface that ensures a pressurized seal.
• 1650W Power Rating: Delivers consistent 1.65 kW of heating power at 120V, optimized for recovery efficiency in various electric water heater models.

Common Questions

• Will this element work if my heater is currently blowing the circuit breaker? A grounded or shorted heating element is a primary cause of electrical furnace and water heater breakers tripping; replacing the faulty unit with this 120V 1650W element typically resolves the issue.
• How do I confirm if my existing element is failing? Use a multimeter to test for continuity across the terminals; an "open" reading indicates the internal filament has snapped and the element must be replaced.
• What are the signs of a failing 100108711 element? Look for lukewarm water, a complete lack of hot water, or a distinct burning smell from the electrical access panel which indicates the copper sheath may have ruptured.
