Lochinvar & A.O. Smith 100330184 Control Board
The Lochinvar & A.O. Smith 100330184 Integrated Control Board is a critical component for managing terminal functions in commercial water heaters and high-efficiency boilers, including the AWH0400 series. Built to handle complex ignition control sequences and safety protocols, this OEM replacement part regulates the draft inducer blower, silicon nitride igniter, and gas valve timing to ensure precise thermal modulation. As a main controller module, it processes inputs from dual thermistor probes and flue sensors to maintain set point accuracy while protecting the heat exchanger from dry fire or overheating conditions.
For contractors, the 100330184 offers a direct-fit solution that eliminates field-programming errors common with universal boards. This HVAC control board features integrated LED diagnostic codes to streamline troubleshooting on the job site, allowing for rapid identification of pressure switch failures or flame sensing issues. Whether you are servicing a Lochinvar Knight boiler or an A.O. Smith commercial gas unit, this board provides the necessary 24V logic and line voltage management to restore full system energy efficiency and operational reliability.
Key Benefits- Direct OEM Compatibility: Engineered specifically for Lochinvar and A.O. Smith commercial units, including the AWH0400, ensuring perfect wiring harness alignment.
- Advanced Diagnostics: Features on-board LED flash codes to quickly identify system faults such as blower prover switch failures or ignition lockouts.
- Optimized Combustion: Precisely manages the pre-purge and post-purge cycles of the draft inducer for safe and efficient venting.
- System Protection: Monitors high-limit switches and flame rectification to prevent hazardous operating conditions and equipment damage.
What are the symptoms of a failing 100330184 control board?
Common indicators include the burner failing to ignite despite a call for heat, the draft inducer running continuously without establishing a flame, or the display showing "No Display" due to a blown F3/F5 fuse on the board circuit.
Can this board be used in both residential and commercial applications?
The 100330184 is primarily used in commercial gas water heaters and high-output boilers. Always verify your specific model number against the manufacturer’s parts list before installation.
Does this board control the gas valve directly?
Yes, it provides the 24V AC output to energize the combination-step opening gas valve after the ignition control board verifies the blower prover switch is closed and the igniter is at temperature.
