Ref. Sensor Gree, Copper Head 15K. SNR-009
The image shows an SNR-009 Senser Gree, Copper Head 15K, a specialized NTC (Negative Temperature Coefficient) thermistor probe used for temperature monitoring in HVAC systems.
Core Specifications & Use
- Model Number: SNR-009.
- Sensor Type: 15K NTC Thermistor. This means at a standard temperature of the sensor should have a resistance of 15 kilo-ohms (k)
- Copper Head Design: The sensing element is encased in a copper probe, which is used specifically for detecting tube temperature. Copper provides high thermal conductivity, allowing the sensor to react quickly to temperature changes in the refrigerant lines.
- Function: It monitors the temperature of the evaporator or condenser coils to prevent freeze-ups and ensure the unit operates efficiently.
Application & Compatibility
- Primary Brand: Specifically designed for Gree Air Conditioners.
- Error Code Solution: Replacing a faulty sensor often resolves common Gree AC fault codes such as F1 or F2.
- General HVAC Use: While optimized for Gree, 15K copper head sensors are also found in various other household appliances like refrigerators, water heaters, and dishwashers for temperature control.
How to Test for Faults
If your AC is showing a sensor-related error, you can verify this part using a multimeter set to the Ohms
setting:
setting:- Measure Resistance: At room temperature it should read approximately 15k
- Check for Change: Hold the copper head in your hand or dip it in warm water. Because it is an NTC sensor, the resistance should decrease as the temperature increases.
- Identify Failure: If the meter shows “OL” (Open Loop), 0 ohms (Short Circuit), or if the resistance doesn’t change when heated, the sensor is defective and must be replaced.
