Error codes for air conditioners MDV

As you know, there are no eternal things and a situation may arise when the MDV air conditioner simply does not turn on. Before grieving over costly repairs, you should call a wizard or independently determine the nature of the malfunction using the error codes given in the electrical diagram or instructions for the device.

Most of the faults and errors are identified by the internal control system of the device, and the corresponding codes, separate for the indoor and outdoor unit, are indicated by LEDs on the panels and control boards. The LED can be on, blinking, and the specific combination indicates the nature of the error. These can be prerequisites for cleaning, adjusting or even repairing the device when it does not react at all to control programs.

Signal lamps 4. These are Run, Timer, Defrost, Alarm. The Run light, when blinking, most often indicates a failure of various sensors. The number and frequency with which the indicator flashes determine the error codes. As an example, a group of errors can be given: E2 - E4 - "Run blinking" - malfunction of the room air temperature sensor, evaporator control sensor, errors in determining the outlet flow temperature. Also, when the Run lamp is blinking, this may mean a failure of the internal memory or an E7 error when reading data from it.

Timer LED displays communication error codes. For example, when it blinks at a frequency of 5 Hz, it means communication errors between the outdoor and indoor unit. The batteries may even just run out.

Sometimes block error codes directly indicate a malfunction of the associated equipment. For example, when the Alarm indicator flashes slowly at the indoor unit, it means that the air conditioner does not turn on due to a malfunction of the outdoor unit. Conversely, a similar LED on the outside is an error code indicating problems with the indoor unit. You may even have to change some parts.

Detailed error codes for each model are given in the user manual. It also contains information on how to fix some faults and problems yourself. A complete list of codes can be found in the reference materials for Midea air conditioners - most of the LED signal combinations are the same as MDV products.
