sensor fault

1、Check whether the resistance of the sensor is normal

(the resistance is 5КΩ in the normal temperature

25 )℃ , when it is abnormal the sensor should be

replaced.

2、Check whether there is short circuit or open circuit in

the wire of the sensor, and whether the plug is

connected well, whether there is welding off or

rosin joint on the electric control board, if there is

any, it should be repaired.

3、When the 1 and 2 are both normal, then the

components or integrated circuit is damaged, the

electric control board should be replaced.

abnormal

1、 Check whether the winding resistance and

operation current of the compressor are normal.

2、Check whether the high and low pressure is normal

when the unit is running.

3、Check (whether the coil pipe sensor is normal)

whether the contact of the inserter on the circuit

board is well, the coil pipe temperature sensor is

fixed, the evaporation of the indoor unit is well,

the key is to check the evaporator temperature

detected by the coil pipe temperature sensor has

reached the cooling or heating temperature.

4、Check whether the surface of the condenser is too

dirty, it should be cleaned when it is too dirty.

5、Check whether the capacitance of the outdoor motor

and the fan is damaged, it should be replaced when
