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

  1. Turn off the air conditioner and disconnect from power for ~5–10 minutes, then reconnect.
  2. Check and clean air filters and ensure proper airflow.
  3. Verify remote control settings and replace batteries if necessary.
  4. Look for obvious loose connections around the sensor leads (only if comfortable doing so).

Technician Only Service diagnostics and repair

  1. Access the internal ambient/room temperature sensor and measure its resistance with a multimeter to check for open or short circuit.
  2. Inspect and reseat sensor connectors, replace wiring if damaged.
  3. 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)

🛑 When to Call a Pro:
  • If error persists after basic reset and filter cleaning
  • If you are not comfortable accessing internal components or using diagnostic tools
  • If sensor or PCB replacement is required and you lack HVAC repair experience
