Midea air conditioner error codes

Midea air conditioner error codes

The tables below contain lists of error codes for several models of the Midea air conditioners. For each error code, there is a short explanation of the type of the malfunction. There are separate tables for the following series of Midea ACs: R series, 9V, 9A, and the Cassette/Ceiling&Floor series. If you’re looking for information on AC Outdoor Units, you will also find it below.

Midea e1 error

Midea e1 error

E1 signals that a thermistor in the indoor unit is faulty. There are two thermistors: a plastic and a copper one. If the plastic one is bad (for example, its continuity is very different from standard or the signal from the PCB fails to reach the thermistor), you will see an E1 code. Please, check the thermistor for continuity and be sure it is well connected to the main control board.

Midea e3 error

Midea e3 error

The E3 error code appears when there is a problem with the fan motor or Start capacitor. Test your AC by turning it off and then on again. If the code appears again, turn it off and push the fan toward you. Then try to run the unit again. If the motor fan starts, there may be a problem in the capacitor.

Check the condenser in the outside unit. Most likely, it has grown dirty and needs to be cleaned. Do that and see if the error has gone. If it has not, contact your local technical service provider.

Midea p5 error

Midea p5 error

If you see the P5 fault code on your unit’s display, there must be a mode conflict. In other words, one of the indoor units is operating in the heating mode, while another one – in the cooling mode.

You cannot set these units to operate in different modes simultaneously. To clear the error, disconnect the breaker and wait about 4 hours to ensure that the capacitors have discharged completely.

You can test-run your indoor units by letting them operate in a cooling or heating mode for a little while.
