The E6 error code is common in air conditioning systems across various brands, with different meanings depending on the manufacturer. These can be grouped into four main categories:
Group 1: Issues with Ambient Temperature or Evaporator Sensor
Errors in this group are related to failures in the ambient temperature or evaporator sensors. Typically, the solution involves disconnecting the unit and contacting a technician for repair.
Examples by Brand:
- General Electric: Open or short circuit in the ambient temperature sensor.
- Split R Midea: Failure in the ambient temperature or evaporator sensor.
- MIDEA Outdoor Unit: Faulty sensor or coil connector.
- Samsung: Open or short circuit in the outdoor heat exchanger sensor.
Group 2: Communication Issues Between Indoor and Outdoor Units
These codes indicate communication failures between the indoor and outdoor units. This can halt the system’s operation entirely. A fault analysis or a technician’s inspection is recommended.
Examples by Brand:
- BOSH: Communication failure between indoor and outdoor units.
- DAEWOO: Malfunction in the indoor temperature sensor.
- TRANE: Communication failure between units.
- GREE: Communication error that stops the compressor or the entire unit depending on the mode.
- ELECTROLUXE, SHARP, KELVINATOR, PANASONIC: Similar issues with signal transmission between units.
Group 3: Pressure or Thermistor-Related Problems
Errors in this group are associated with pressure issues or faulty thermistors. These failures are often critical and require professional attention.
Examples by Brand:
- York (Central A/C): Low-pressure discharge protection.
- HAIER: General pressure protection.
- FUJITSU: Open coil thermistor.
- PANASONIC: Failure to receive communication signals from the indoor unit to the outdoor unit.
Group 4: Compressor Start-Up Problems
In this case, the E6 error code is associated with compressor start-up issues, particularly in Daikin systems. Both the compressor and the electrical system need to be inspected to resolve the fault.
