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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInlet-type blocked airflow detection for combustion safety shutoff\u003c\/li\u003e\n  \u003cli\u003eInterrupts control circuit upon detection of inlet obstruction\u003c\/li\u003e\n  \u003cli\u003eOEM-style replacement for AO SMITH water heater safety systems\u003c\/li\u003e\n  \u003cli\u003eDirect integration with appliance control board or gas valve circuit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement inlet switch for AO SMITH gas water heaters requiring inlet-type blocked airflow safety switches.
