Lochinvar & A.O. Smith 100111056 Prover Switch
The Lochinvar & A.O. Smith 100111056 Blower Prover Switch is a critical safety component engineered for precise airflow monitoring in high-efficiency commercial gas water heaters. As a direct replacement for the NS2-0544-00 air pressure switch, this assembly ensures the inducer fan effectively clears combustion gases before the ignition sequence initiates. This OEM replacement part is built with a rugged pneumatic diaphragm that converts pressure differentials into electrical signals, preventing hazardous exhaust buildup. Designed specifically for compatibility with A.O. Smith BTH 100-250, SUF, and HCG series models, it provides reliable HVAC pressure sensing in demanding environments. The 100111056 assembly includes the integrated mounting bracket and necessary pneumatic tubing, facilitating a streamlined installation for service technicians. By accurately "proving" blower operation, this commercial water heater switch maintains system efficiency and prevents nuisance lockouts caused by inadequate venting or blocked flue collectors.
Key Benefits:- Direct OEM Compatibility: Verified 100111056 replacement for the Cleveland Controls NS2-0544-00, ensuring exact fitment and electrical calibration.
- Enhanced Safety Logic: High-precision differential pressure sensing prevents the gas valve from opening if exhaust flow is restricted or the blower underperforms.
- Comprehensive Kit: Includes the blower prover switch, mounting hardware, and tubing for immediate field replacement.
- Versatile Application: Optimized for use with both natural gas and propane high-efficiency high-recovery commercial units.
- What are the signs of a failing prover switch? Common indicators include the unit failing to spark after the blower starts, or "Air Proving Switch" error codes on the digital controller.
- Will this fix a blocked flue error? While the switch detects the error, technicians should first inspect the pneumatic tubing for condensation or debris and verify the venting is clear of obstructions.
- Is the mounting bracket included? Yes, the 100111056 comes as a complete assembly with the pre-installed bracket for standard bolt-on replacement.
