Friedrich Air Conditioning 67812094 Sensor 323613-751 the Armstrong 812 series is

the Armstrong 812 series is renowned for its resistance to water hammer and its ability to handle dirt and scale through a self-scrubbing action

this specific part number is designed for a 1/4-inch hub bore

This 1-inch NPT gas valve is a normally closed solenoid valve designed to provide positive shut-off when de-energized

the 383-500-601 is used for both supply and return temperature sensing depending on how it is mapped to the boiler's control terminals

you should typically see resistance between 5 and 10 Ohms if the circuit is intact

Friedrich Air Conditioning 67812094 Sensor 323613-751 the Armstrong 812 series isThe Friedrich Air Conditioning 67812094 Sensor is a precision indoor air inlet temp sensor designed for accurate thermal regulation in select HVAC systems. Engineered as a high sensitivity thermistor, this ambient temperature sensor monitors the intake air to provide real time data to the control board, ensuring the unit maintains setpoints with minimal deviation. This 10k? resistance component (at 77F) is critical for preventing common system errors
