Refrigeration Sensor Error — the cabinet temperature sensor (thermistor) is reporting an out-of-range reading or has lost communication with the controller
Equipment: Dixie Narco Glass-Front Vending Machine
Step-by-Step Troubleshooting
- Test the temperature sensor with a multimeter — an NTC thermistor should read approximately 10K ohms at 70°F; infinite resistance indicates a broken wire or failed sensor
- Inspect the sensor wiring from the thermistor to the control board — look for chafed, pinched, or corroded wires, especially where the harness passes through the cabinet wall
- Check the sensor connector at the control board — a loose or corroded connector causes intermittent sensor errors
- Compare the sensor reading to an independent thermometer placed in the cabinet — if readings differ by more than 5°F, the sensor is out of calibration and should be replaced
