Common Questions:

What are the signs that a blocked outlet switch has failed?
Technicians typically observe a specific error code on the digital controller indicating a "Blocked Outlet" or "Pressure Switch Open" fault, even if the venting appears clear. This often points to a diaphragm failure or electrical continuity issue within the switch.

Is the 100111058 compatible with both LP and Natural Gas units?
Yes, this switch is designed for use in BTH/SUF/HCG units ranging from 100,000 to 250,000 BTU for Natural Gas and up to 199,000 BTU for Propane (LP) configurations.

Can I use an aftermarket universal switch instead?
For commercial safety circuits, it is highly recommended to use the genuine A.O. Smith 100111058. Calibration points for blocked outlet detection are specific to the blower and vent assembly; using an incorrect part can lead to nuisance tripping or unsafe operating conditions.
