Lochinvar & A.O. Smith 100109635 Heating Element

The Lochinvar & A.O. Smith 100109635 Heating Element is a heavy-duty, 10.75-inch screw-in component engineered for high-demand commercial water heater and residential applications. This OEM water heater part features a Corrogard zinc-plated copper sheath, providing superior resistance to scale buildup and corrosion in harsh water conditions. Designed for dual-voltage versatility, this 4500W 208V / 6000W 240V element delivers reliable thermal transfer, ensuring rapid recovery times for electric water heaters. As a direct 9003952115 replacement element, it maintains the structural integrity and performance specifications required by Lochinvar, A.O. Smith, State, and Reliance systems. For successful field heating element installation, always verify that the tank is fully submerged to avoid dry-firing the unit. This mid-line screw-in element is a vital HVACR replacement part for technicians performing water heater maintenance on storage tank water heaters requiring precise wattage outputs at specific voltages.

• Dual-Voltage Compatibility: Operates at 4500W at 208V or 6000W at 240V for flexible field application.
• Corrosion Resistance: Corrogard zinc-plating prevents premature failure caused by sediment and mineral deposits.
• High-Efficiency Heating: Copper heating element construction ensures optimal heat conduction and energy efficiency.
• Precision Fit: 10.75-inch length and standard screw-in threads ensure a leak-proof seal in compatible A.O. Smith tanks.

What is the correct way to test a 100109635 element?
Using a multimeter set to the lowest resistance (Ohms) setting, check the terminals; a functional 6000W/240V element typically reads between 5 and 25 Ohms.

Can I use this in a 120V water heater?
No, this element is specifically rated for 208V or 240V systems; using it at 120V will result in significantly reduced heat output and potential system issues.

How do I prevent the element from burning out immediately after installation?
Always ensure the water heater tank is completely filled and all air is purged from the hot water lines before restoring power to the circuit to prevent dry-firing.
