What Does the E6 Error Mean?

The E6 error in Giatsu air conditioners typically indicates a problem with the internal fan motor or communication between the indoor and outdoor units. This may stem from a fault in the electronic board that controls the motor or an incorrect connection.

Steps to Solve the E6 Error

Connection Check

Before panicking, let’s go through some basic checks:

  1. Inspect electrical connections: Ensure all connections are secure without loose or improperly connected wires. Sometimes, a simple error in connecting the wires can cause this problem.
  2. Restart the air conditioner: Disconnect the unit from the power source, wait a few minutes, and reconnect it. This may reset the system and resolve the error.

Fan Inspection

If the connections are correct, the next step is to take a look at the fan:

  1. Verify the fan spins freely: If the fan is stuck or not rotating correctly, it could be the cause of the E6 error.
  2. Cleaning: Dust and dirt buildup can sometimes hinder the proper operation of the fan. Clean the blades and surrounding areas carefully.

Consult with a Technician

If, after checking connections and the fan, the problem persists, it’s time to call a specialized technician. There might be a more complex issue with the electronic board or the fan motor that requires professional repair.

Real Cases of E6 Error

In some instances, users have reported that the E6 error was due to a reversed connection in the 4-wire hose going from the indoor unit to the outdoor unit. Specifically, the network cables going to terminals N(1) and L were placed in reverse. If you’re comfortable checking this and have electrical knowledge, you could attempt to verify it. Otherwise, it’s best to let a technician handle it.

Preventive Maintenance

To avoid future problems, regular maintenance of your air conditioner is crucial. Cleaning the filters and ensuring all connections are correct can save you a lot of headaches.
