Description
The Daikin-McQuay 128855J Thermistor Assembly is a temperature sensing component used to monitor changes in air or coil temperature inside equipment. The thermistor changes its electrical resistance based on temperature variation, allowing the control board to read accurate temperature signal and adjust system operation accordingly. It is commonly used for sensing indoor coil or air temperature feedback. Within HVAC systems, it is installed in air conditioning and heat pump units where precise temperature monitoring is needed for stable system control.
