●What to do if E6+Room Temperature/e6/e4 fails?
In some inverter air conditioners, there is a fault code of E6+room temperature/e6/e4, which you may rarely encounter. So, what is this fault? How should after-sales service handle it? Let's discuss it together.
1. What is E6+Room Temperature/E6/E4 Fault?
The indoor unit displays "E6+Room temperature/e6/e4" which indicates a communication failure between the indoor unit mainboard and the display panel. As shown in the figure above, E6+Room temperature display is code+Room temperature indicator light, and the figure below shows the e6 and e4 fault codes.
2. Why does a fault occur?
In order to distinguish the internal and external communication failures of E6, some models have these codes. Usually, when the air conditioner is running, normal communication information is carried out between the main board and the display board. When the detection signal is abnormal, the control system reports a fault and shuts down for protection.
3. What are the common causes?
1. The internal mainboard is faulty.
2. Connection between the main board and the display board.
3. Display panel failure.
4. How to troubleshoot?
