Air conditioners Jax issue error codes due to the presence of a self-diagnostic function. This option is present in most modern air conditioners. It allows you to quickly find the problem using only the instructions for use. In some cases, the user can independently eliminate the violation and start the system without calling the service center and saving money and time. You can find the error codes for jax air conditioners in the tables below.
Jax air conditioner errors
Air conditioner Jax E2 - No contact with the room air temperature sensor;
- E3 - No communication with the evaporator temperature sensor;
- E4 - No communication with the condenser temperature sensor;
- E5 - Failure in pumping condensate;
- E6 - Malfunctions in the outdoor module;
- E7 - EEPROM failure (details in the instructions);
- E8 - The condensate container is full for more than three minutes.
Error codes on the indoor unit display
| Jax air conditioner error code | Breaking | Instructions |
| operation + timer + def / fan | Too much voltage applied to the compressor | Disconnect the device from the mains |
| water alarm LED (blinking) | Water collection container exceeded less than 3 minutes | Manually start the pump down |
| water alarm LED (continuous) | The water collection container has exceeded the quantity for more than 3 minutes | Emergency mode is deactivated when unplugged |
| pre / def (def / fan) | No communication with the condenser temperature sensor | Repairing the sensor |
| All the lights are blinking | No communication with outdoor unit | Repairing the sensor |
| timer | No communication with room temperature sensor | Repairing the sensor |
| operation | No communication with the evaporator temperature sensor | Repairing the sensor |
| timer + operation | EEPROM failure | Replacing the main board |
