Ao Smith 100110715 Blocked Inlet Switch

Product Description

The AO SMITH 100110715 is a blocked inlet switch designed to detect airflow obstruction at the inlet of a water heater or combustion air system. When the inlet becomes blocked, the switch interrupts the control circuit to shut down the appliance and prevent unsafe operation. This is a safety-critical component found in gas-fired water heaters and similar appliances where proper combustion air flow must be confirmed before operation. Installation is typically performed by a licensed plumber or HVAC technician during routine service or warranty repair.

The 100110715 blocked inlet switch is used in residential and light commercial gas water heater applications where inlet airflow monitoring is required as part of the safety control circuit. It is installed in the combustion air inlet path and wired into the appliance control board or gas valve circuit. Where specific compatible model numbers are available, they should be confirmed against AO SMITH service documentation prior to installation.
