the sampling tube must be ordered separately to match the specific width of your ductwork

This high-density sensor is built to withstand high-temperature combustion environments

By replacing a worn or missing dust proof cover

This is critical for HVAC zone control when the radiator is located in a recess or under a cover where a built-in sensor would be "fooled" by trapped heat

Friedrich Air Conditioning 68700152 Temp Sensor 320819-301 the sampling tube must beThe Friedrich 68700152 Ambient Temperature Sensor is a critical OEM replacement part engineered for precise thermal feedback in Friedrich air conditioning systems. As a veteran technician knows, a drifting or failed thermistor leads to short cycling or incorrect compressor modulation. This HVAC temperature sensor monitors outdoor or intake air conditions, providing the control board with the resistance values needed to maintain energy efficiency and
