Introduction of maintenance methods for common faults of Midea air conditioner

1、 Troubleshooting method of filter reset

1. Check whether the connecting line group of the filter reset switch is broken, broken or connected reliably, and make corresponding adjustment if there is any problem;

2. Check whether the dust removal mechanism of the filter screen of the air conditioner is stuck or not, and make corresponding adjustment if there is any problem;

3. Short circuit the reset switch on the electronic control main board. If the air conditioner fault cannot disappear, it can be determined as the main board fault of the air conditioner;

4. Block the reset switch with light, and use a multimeter to detect the reset switch terminal. If the photoelectric switch is detected as open circuit, it is determined that the reset switch is faulty;

2、 Troubleshooting method of water full

1. Check whether the water level switch connecting line group is broken or broken, and whether the water level switch connector contacts reliably. If there is a fault, corresponding adjustment is needed;

2. Turn the water level switch to the bottom to detect whether the water level switch is in the short circuit state; then turn the water level switch to the top to detect whether the water level switch is in the open circuit state with a multimeter; if there is any discrepancy between the two, it can be determined that the water level switch is faulty;

3. If the water level switch connector on the air conditioning main board is short circuited, if the water full fault does not disappear, it can be determined as the air conditioning main board fault;
