The breaker trips at once when it Measure insulation resistance to ground to see if there is any leakage. is set to "ON". Trip of breaker or blow of fuse The circuit or the part of the air conditioner has malfunction. They heat and break the insulation The breaker trips in few minutes when it is set to "ON" and lead to short circuit or creepage. Measure the insulation resistance or eliminate the malfunction one by one. If the breaker itself has Air conditioner can not start up malfunction, then replace the breaker. The air conditioner No power Check power supply circuit. Power plug is not well plugged in and poor connection Check if the plug is properly plugged in and make the loose contact firm. does not react after it is powered ( after Fuse of controller burnt out Change controller fuse the plug is inserted, the buzzer does The transformer connection is loose or has bad not sound and the contact or the transformer has malfunction remote startup has Fasten the wiring; measure the output voltage of the transformer, if it is incorrect, change the transformer no response) The remote controller Controller is broken Check remote controller Remote controller is short of power Change batteries Remote controller malfunction First, press the manual switch button AUTO, does not receive signals (after it is powered, the buzzer above methods. If it runs normally after will sound, unless it has if there is no response,check based on the Receiver loose or poor connection malfunction) pressing the button,check again whether the installation position and the connection wire of the reception head is correct. If it is Receiver is broken Power voltage is too low correct,then replace the receiver or the remote controller. heck the voltage. If it is lower than 10£¥ of the rated voltage, check the cause, improve the power supply condition and add the stabilized voltage power supply. Controller malfunction (IC2003 broken, creepage of parallel capacitor of relay loop, relay is broken etc.) In cool, heat mode,the outdoor unit and compressor will not run. Change controller Wire loose or wrong connection Correctly wire according to the drawing Improper setting of temperature Adjust setting temp. Improper set of temperature Adjust set temperature If cooling (heating) load is proper Check the forecasted load of cooling (heating) The refrigerant has leakage or is insufficient Malfunction of refrigerant flow Leakage between the high pressure and the low pressure inside the compressor Malfunction of four-way valve Poor COOL(HEAT) operation Local block of capillary Blockage of cooling system Heat insulation for the connection pipes of the indoor unit and the outdoor unit is bad. heck and fill the leakage, then vacuumize it and supplement the refrigerant as required Replace the compressor Replace the four-way valve Replace the capillary Judge whether the system is blocked by observing the condensation of evaporator and the pressure value of the high pressure manometer and take measures to deal with the system. Make sure that heat insulation for the thick and thin pipes is good. Heat insulation must also be provided for the joint andthe exposed part of the copper pipe . Block of outdoor heat exchanger Clean the dust accumulated on the surface of the heat exchanger. Air filter were blocked Clean the filter Fan speed was set too slow Air circulation is insufficient Fan rotation speed becomes low The installation position of the outdoor unit is not appropriate. The outdoor temperature is too high. The air tightness is not enough. People come in and out too frequently. There are heating devices indoors. To set the fan speed to high or middle speed Capacitor damage Replace the capacitor Motor damage Replace the motor Good ventilation must be provided for the installation position of the outdoor unit. Properly install the rainproof plate or the sunproof plate. If the maximum cool air still can not meet the requirement, it is suggested to replace the air conditioner. Keep certain air tightness indoors, try not to use electricalappliance with large quantity of heat The indoor fan motor is burned or breaks or has the heat protector malfunction. The fan does not run when it is set to supply air. In the cooling and heating mode, the compressor runs, but the outdoor fan does not run. The compressor is too hot and leads to the action of the protector. The built-in heat protector of the motor breaks frequently because the motor is abnormal. Replace the fan motor Wrong connection Make the correction connection based on the circuit drawing. The fan capacitor has open circuit or is damaged. Replace the fan capacitor of the same type and same specification. The outdoor fan motor is damaged. Replace the fan motor Wrong connection Make the correct connection based on the circuit drawing The outdoor fan capacitor is damaged. Replace the fan capacitor Malfunction of compressor Replace the compressor Breakage of running capacitor of compressor Replace the capacitor The voltage is too low or too high. Manostat is recommended. Wrong wire connection Connect the circuit diagram correctly The protector itself has malfunction. The refrigerant is not enough or is too much. The compressor is too hot and leads to the action of the protector. Replace the fan motor or the defective part. The capillary is blocked and the temperature rises. The compressor does not run smoothly or is stuck. The air discharge valve is damaged The protector itself has malfunction. Use the multimeter to check whether the contact of the compressor is on when it is not overheated. If it is not on, then replace the protector Adjust the volume of the refrigerant Replace the capillary Replace the compressor Replace the protector The torque of the swing motor is not enough The swing fan does not run. Wrong connection The controller is damaged(IC2003 is damaged, the swing relay can not close, etc) First, check whether the connection is wrong. If no, replace the parts Drainage pipe blocked or broken Change drainage pipe Water leakage Wrap of refrigerant pipe joint is not close enough. Re-wrap and make it tight. Fan of indoor unit contacts other parts. Adjust fan location. Foreign object in indoor unit Take out the foreign object. Compressor shakes too much. Abnormal sound and shake Adjust support washer of compressor, and tighten loosen screws. Touch of pipeline of outdoor unit Separate the touching pipeline. Touch of inner plates 1. Tighten connect screw. 2. Stick absorbing clay between plates. Louver of outdoor unit touched outer case. Adjust location of louver. Abnormal sound inside compressor Change compressor Abnormal solenoid sound from 4-way valve when heating Circuit-short inside solenoid of the valve and change the solenoid valve. There are no heating malfunctions in the above for the cooling only unit. PG motor locked protection H6: Probable reasons: 1. Air vents were blocked which may cause the fan speed is too slow; 2. Fan blade locked; 3. Motor locked; 4. Fan motor capacitor damaged; 5. Motor damaged (ordors, winding, open circuit or shortcircuit are not normal, when testing the winding, pls distinguish whether the motor body cause temperature is too high so that bring on the thermal protector starts up) 6. IC board damaged (during normally running, there are voltage at both capacity input and output) 7. Mainboard damaged. 8. Motor thermal protection. Disposal methods: 1. Remove the obstruction; 2. Reassembling; 3. Replace motor; 4. Replace capacitor; 5. Replace motor; 6. Replace circuit board; 7. Replace mainboard; 8.Under the normal circumstances, the motor will not act, but in other circumstances, such as evaporator is very dirty, to much dust attached on the fan blade that will cause the motor overload running, so that during the operation, frequent thermal protection will happen, so it is need to be cleaned or replaced.
