Panasonic cwa50c2867 Ambient Temperature Sensor

Product Description

The PANASONIC cwa50c2867 is a complete ambient air temperature sensor assembly designed for use in Panasonic room air conditioning systems. Known in service documentation as the Ta sensor, this thermistor-based component monitors the ambient temperature of the conditioned space and sends that signal to the unit control board to regulate compressor and fan operation. It is a direct OEM part sourced from Panasonic and is installed by licensed HVAC technicians performing sensor diagnostics or component-level repairs on ductless and room air systems.

This sensor is intended for room air conditioner applications where the ambient temperature input has failed, drifted out of calibration, or been physically damaged. The Ta designation refers to the ambient air thermistor function, distinguishing it from pipe or discharge temperature sensors used elsewhere in the refrigerant circuit. Technicians replacing this part should verify the fault code or sensor resistance reading against Panasonic service documentation before ordering to confirm this is the correct sensor for the failure mode present.

Key Features

• OEM Panasonic replacement sensor assembly for room air conditioner ambient temperature monitoring
• Ta designation confirms ambient air thermistor function, not pipe or coil temperature sensing
• Complete assembly replaces the full sensor and lead wire as a single service part
• Thermistor-based design provides accurate temperature signal input to the main control board
• Direct Panasonic part ensures correct resistance characteristics and connector fit

Compatibility

Designed as an OEM replacement ambient temperature sensor for Panasonic room air conditioner and ductless mini-split systems. Verify the specific model number against Panasonic parts documentation before installation to confirm fitment.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with Panasonic room air equipment. Disconnect power to the indoor unit at the breaker and confirm voltage is absent before accessing the sensor connector on the main control board. Handle the thermistor element carefully to avoid mechanical damage that would affect resistance readings. Confirm the replacement sensor reads within the expected resistance range at ambient temperature using a calibrated multimeter before restoring power.
