1. |
Q £º No power supplies or fuse blew |
|
A £º Check if there is no power supplies, check the socket and plug to see if they are loosen and repair them, change the blew fuse. |
2. |
Q £º Voltage of power is too low |
|
A £º Find out causes when the power voltage is 10% lower than the rated voltage |
3. |
Q £º There is no response for switch |
|
A £º Check if the switch is broken off or if there is mechanical malfunction, check by multimeter to see if it is connected, if the melt points are not connected, change another switch of the same model and specification. |
4. |
Q £º Temperature controller is out of control |
|
A £º Turn the temperature controller to the lowest temperature first, if the compressor cannot be startup, check with multimeter to see if the contact is connected. If the contact of temperature controller cannot connect in high indoor temperature, change a new temperature controller. |
5. |
Q £º Burned of compressor motor |
|
A £º Check by multimeter, if there is circuit-short, circuit-break or wires earthed in the coil of hermit compressor motor, change another compressor that has the same model and specification. |
6. |
Q £º Compressor crankshaft jammed |
|
A £º Knocks and librates the shell of compressor with rubber stick or hammer that is underlaid by wood block may startup the compressor; if the compressor still cannot run, change compressor |
7. |
Q £º Malfunction of crystal oscillator or resetting circuit |
|
A £º Change the blooey elements |
1. |
Q £º Lack of refrigerant or leakage happened |
|
A £º Leak detect, then vacuumize after filled in the leakage, fill in refrigerant according to stipulation. |
2. |
Q £º Cooling system is blocked. |
|
A £º Check if the system is blocked by the same method of observing condensation on evaporator and pressure value on the high pressure meter, and settle it by system. |
3. |
Q £º Fan don't run or airflow is not enough |
|
A £º Check if the fan is burned, or incorrect wire connection; change a new fan if it is burned. |
4. |
Q £º Too much dust on filter |
|
A £º Clean the filter |
5. |
Q £º Malfunction, circuit-short or circuit-break at electric regenerator |
|
A £º Change a new electric regenerator |
6. |
Q £º Compressor is in a low efficient |
|
A £º Change a new compressor |
7. |
Q £º Refrigerant is too much |
|
A £º Discharge the redundant refrigerant in system |
8. |
Q £º Circuit-break or circuit-short at indoor sensor |
|
A £º Change sensor or relative elements |
9. |
Q £º Relay in compressor cannot suck and close normally |
|
A £º Change compressor relay |
1. |
Q £º The set temperature of temperature controller is too high |
|
A £º Lower the set temperature |
2. |
Q £º The filter is so dirt that the inlet vent is blocked |
|
A £º Clean the filter |
3. |
Q £º Outdoor condenser is blocked for there is obstruction at outlet. |
|
A £º Clean condenser |
4. |
Q £º Power voltage unsteady |
|
A £º Adjust power voltage |
5. |
Q £º The indoor sealing performance is not enough; people come in and out frequently, or there is heating equipment in the room. |
|
A £º Adjust indoor environment |
6. |
Q £º Outdoor temperature is too high (above 43 ¡æ ) |
|
A £º Turn off the unit |
7. |
Q £º Refrigerant is not enough or too much |
|
A £º Add refrigerant or discharge redundant refrigerant in system |
8. |
Q £º Door or window is opened |
|
A £º Close the door or window |
9. |
Q £º There is obstruction in air inlet or outlet vent |
|
A £º Remove the obstruction |
1. |
Q £º Air filter is dirty or blocked |
|
A £º Clean filter to improve airflow |
2. |
Q £º Doors or windows aren't close well |
|
A £º Close the door or window to preserve cool (heat) |
3. |
Q £º Room temperature is set too low to heat |
|
A £º Rise the set temperature |
4. |
Q £º Heat pharmaceutical leaks |
|
A £º Contact service center |
5. |
Q £º The outdoor environment temperature is lower than -5 ¡æ |
|
A £º Affect the function of air conditioner |
6. |
Q £º Abnormal of control circuitry |
|
A £º Contact the service center |
