Lochinvar & A.O. Smith 100093696 Control
When you're dealing with a Polaris water heater that won't fire up, the Lochinvar & A.O. Smith 100093696 Control is the specific K Box ignition control kit required for units manufactured before serial number 9833. This genuine OEM replacement part is critical for managing the gas-fired combustion sequence, supervising the hot surface igniter, and monitoring flame rectification to ensure safe operation. As a veteran tech, you know that intermittent lockouts on these older Polaris models often trace back to a failing 100093696 ignition module. This kit provides the exact microprocessor-based logic needed to restore the proven pilot timing and redundant gas valve sequencing required for high-efficiency condensing performance.
Key Benefits
- Ensures accurate flame sensing and prevents hazardous unburned gas accumulation during the trial for ignition.
- Direct OEM compatibility for Polaris water heaters built before 1998, eliminating the need for field-modified wiring harnesses.
- Rugged K Box housing protects internal solid-state circuitry from the high-humidity environment typical of condensing boiler rooms.
- Provides precise spark-to-burn timing to minimize combustion noise and maximize thermal recovery efficiency.
Common Questions
What are the symptoms of a failing 100093696 control box?
Common signs include the blower motor running without a spark or hot surface glow, or the unit initiating ignition but dropping the flame signal after a few seconds (flame rectification failure).
Will this work for Polaris units made after 1998?
No. This specific 100093696 ignition control is engineered for units before serial number 9833. Always verify the serial plate to prevent board damage from incompatible voltage cycles.
Is this a direct "plug-and-play" replacement?
Yes, as an OEM K Box control, the terminal designations match the original factory wiring schematic, though we recommend checking your grounding wire to ensure a strong flame signal.
