What does Midea E1 error code mean?

There is an error code in both the outdoor and indoor unit. We are assuming that you are looking at the error code from the indoor unit. As most of the time consumers won’t randomly climb out of their window to access the outdoor condenser unit. For most of the Midea Aircon models, E1 error code means that there is a communication problem between the indoor and outdoor unit. This means that there is a signal issue between the indoor pcb and outdoor pcb. Therefore, they are not communicating effectively. Typically the indoor unit will communicate to the outdoor unit to let it know how hard it needs to work. As a result they can provide sufficient cool air to cool the room. If there is an issue with the communication E1 error code will appear.

How to troubleshoot E1 error code?

The first step in troubleshooting for E1 error code is to examine how many indoor units are having E1 error code. We are assuming that it is a multi split unit. However, if yours is a single split unit, then obviously only 1 unit will be having that error. If this is a multi split unit and all units are having E1 error code, then the issue is definitely with the outdoor pcb.

We will then proceed to check the outdoor unit for parts that may be malfunctioning. However, if only 1 indoor unit is experiencing E1 error code in a multi split unit. Then chances are, the indoor pcb is malfunctioning. Nonetheless, we have experienced quite a number of cases in which the outdoor pcb is malfunctioning even when only 1 indoor unit is having this error code. Hence the technician may have to check in depth to find out. Also do note that there are 2 pcb units in a multi split system 3 Midea condenser unit. The technician will also have to figure out which particular pcb is malfunctioning.

Solutions to Midea E1 error code

As mentioned in the troubleshooting steps earlier. If we can isolate and find out that the issue is from the indoor unit. We will just have to change the indoor pcb. Otherwise, we will typically need to replace the outdoor main control board or the inverter board. That will depends on which item is faulty. Do note that sometimes E1 error code may occur with other error code as well. Hence, multiple items will need to be replaced instead of just one. Other items that may require further check include the reactor. However there are some models that do not contain reactors.

Estimated Cost of Repair

The estimated cost of repair that we provide below is for a system 1 unit that contains a reactor. For multi split unit the price may differ significantly from the price listed below. Do check with us if there are any spare parts available. As some parts may be obsolete. And we can only use refurbished parts to repair for you.

Conclusion

To sum up, assuming if you are using a multi split model. The issue can typically be isolated by figuring out how many indoor units are facing E1 error code. Though from time to time, even one unit having E1 error code may be due to outdoor pcb having issue. Also for outdoor pcb, the technician will have to figure out which particular pcb is causing the problem. Hence it makes sense to engage a trained technician to do your Midea Aircon repair. Do let us know if you need any help in your Midea Aircon repair.
