What Does Error E1 Mean?
The Candy Air Conditioner E1 error indicates a communication failure between the indoor and outdoor units, primarily linked to issues with the ambient temperature sensor. This can include a faulty thermistor, loose connections, or problems with the control board. When E1 occurs, the unit may stop cooling and the display could become unresponsive, often persisting even after a restart.
Common Symptoms:
- Unit displays E1 on the digital display
- System may stop cooling or shut down when E1 occurs
- Error persists after device restart
Possible Causes
- Faulty ambient temperature sensor (thermistor) (medium)
- Loose or defective sensor connector wiring (medium)
- Control board (PCB) degree of failure related to sensor circuit (low)
How to Fix Error E1
DIY Fix Basic troubleshooting for E1 error
- Turn off the air conditioner and disconnect from power for ~5–10 minutes, then reconnect.
- Check and clean air filters and ensure proper airflow.
- Verify remote control settings and replace batteries if necessary.
- Look for obvious loose connections around the sensor leads (only if comfortable doing so).
Technician Only Service diagnostics and repair
- Access the internal ambient/room temperature sensor and measure its resistance with a multimeter to check for open or short circuit.
- Inspect and reseat sensor connectors, replace wiring if damaged.
- Test or replace the control board if sensor circuit issues persist after verifying sensor and connections.
Parts needed: Temperature sensor (thermistor), Wiring harness/connectors, Control PCB (if needed)
