Sanyo HVAC CWA50C2800 Temperature Sensor

The Sanyo HVAC CWA50C2800 Temperature Sensor is a critical OEM replacement thermistor designed for precision thermal monitoring in split and multi-split air conditioning units. Engineered to provide high-accuracy feedback to the main control board, this NTC temperature sensor ensures the system maintains stable refrigerant cycles and indoor air temperatures while preventing coil freeze-ups or compressor overheating. This specific Sanyo HVAC part is calibrated for a standard operating range of -50°C to 150°C, delivering the low-resistance tolerance required for high-efficiency inverter systems.

For field technicians, the CWA50C2800 is often cross-referenced as a Panasonic HVAC sensor, supporting a wide array of ductless mini-split models including the CSS, CS-E, and CS-XE series. Replacing a faulty or drifted sensor with this genuine component restores proper energy-saving performance and prevents HVAC error codes related to ambient or discharge temperature faults. Its robust, moisture-resistant housing is built to withstand the high-humidity environments found in evaporator cabinets and industrial air handlers.

• Precise Thermal Feedback: Maintains ±2% accuracy to ensure optimal delta-T and system efficiency.
• OEM Compatibility: Exact drop-in replacement for Sanyo and Panasonic mini-split sensors, eliminating the need for universal field splicing.
• System Protection: Critical for monitoring evaporator temperature to prevent ice accumulation and liquid slugging in the compressor.
• Energy Efficiency: Provides the data needed for the inverter to modulate compressor frequency, reducing unnecessary cycling and wear.

Is the CWA50C2800 interchangeable with other Sanyo thermistors?
This sensor is specifically calibrated for a defined resistance-temperature curve. While it may look similar to other air or pipe sensors, you must verify the specific Ohm rating at 25°C (77°F) against your service manual to ensure the control board receives the correct voltage signal.

What are the symptoms of a failing Sanyo temperature sensor?
Common indicators include the indoor unit "short cycling," evaporator coils freezing over, or the system throwing specific self-diagnostic LED codes. Always test the sensor's resistance with a multimeter before replacement to confirm it has drifted out of spec.

Does this sensor come with the connector?
Yes, this is a complete OEM temperature sensor assembly, including the pre-terminated plug for direct connection to the PCB, ensuring a secure and corrosion-resistant interface.
