Oaks cabinet air conditioner shows E4

Oaks air conditioner shows E4, which means that the air conditioner compressor is not working properly. Common causes include exhaust temperature sensor failure, system fluorine deficiency, dust accumulation on external machines, and short circuit of motherboard capacitors. The details are as follows:

1. Exhaust temperature sensor failure: A faulty exhaust temperature sensor will cause the system to misjudge the state, causing the air conditioner to display an E4 error. If the air conditioner is cooled normally, but the error sign is still displayed, you need to contact the after-sales service to replace the sensor;

2. Lack of fluorine in the system: Insufficient refrigerant in the air conditioner will cause the compressor to work more intensively and the tube temperature will overheat, thus displaying an E4 error. At this time, it is necessary to contact the after-sales service to replenish the refrigerant;

3. Dust accumulation in the external machine: Serious dust accumulation in the external engine can easily lead to the difficulty of heat exchange between the outside air and the radiator, resulting in excessive load and failure of the compressor. Generally, it can be solved after cleaning the external machine;
