Faults occur during the operation of the air conditioner
The reason why there is no cooling at all under refrigeration conditions
The fan motor does not rotate
1. Poor plug contact or power cord breakage is the main fault, the power cord must be replaced and the plug checked.
2, the electrical contact is poor or the thermostat is faulty, find out the cause of repair or replace the components.
3, capacitor contact is poor or damaged, need to be repaired.
4, parts break, fan motor power loss, find out the cause after repair.
5, fan motor, check whether the fan leaf is stuck, whether the motor winding is damaged, if damaged should be replaced.
Fan motor can run, compressor can not work
1, the voltage is too high or too low (need to be equipped with 2.5 times the power of the regulator), the current is large, resulting in the compressor overload protector action.
2, the power capacity is too small, the pressure drop is large, the compressor is protected and stopped.
3. Wiring error.
4, there is a problem with the electrical line, the compressor can not run.
5, overload jump off.
6. The control line is faulty.
7, the compressor itself is faulty, need to replace the new compressor.
The compressor works, but there is no cold air
The compressor works, but there is no cold air
1, refrigeration circulation system leakage.
2, the refrigeration circulation system is blocked, the capillary or dryer filter is all blocked, the evaporator can not get the refrigerant and not cooling.
3, the compressor itself is faulty, please replace the compressor.
Insufficient heat under heating conditions
There is hot air, but the room air is not warm
1. Improper installation position, poor air flow, please adjust or reinstall.
2. The air filter is dirty.
3. The system is blocked. Check capillaries, filters, bivalves, etc.
4. Doors and Windows are not tightly closed.
5. The room is too big.
6. The outdoor temperature is too low.
7. The condenser frost is too thick.
8. If the air volume is small, whether the fan power is small or the capacitor is invalid, or the fan speed is slow or the fan is bad.
9. Insufficient refrigerant.
The compressor is running, but the air supply is not hot enough
1. The installation position is not good.
2. The outdoor temperature is low, the temperature difference between indoor and outdoor is large, and the room cannot be heated up.
3. The cooling circulation system is blocked.
4. The refrigerant leaks, and the cooling circulation system cannot perform the normal heating function.
Stop the compressor as soon as it starts
1. The installation position is not good, the air flow is blocked, the condenser (indoor side heat exchanger) effect is not good, the exhaust pressure is too high and the automatic shutdown.
2. If the voltage is too low or too high, the compressor protector acts.
3. The power supply capacity is insufficient, the line voltage drop is large, and the compressor current is too large, causing the compressor protector to act.
4. The capacitor contact is poor or damaged, so that the compressor can not operate normally.
