The failure for
temperature sensor of
indoor coil temperature
a. The indoor coil temperature sensor loose;
b. The indoor coil temperature sensor is failure;
c. The indoor control board is failure.
a. The EEPROM chip loose;
b. The indoor control board is failure
Indoor fan motor run
abnormally
a. There are something block the indoor fan motor;
b. The fan motor cord connect loose; c.
The fan motor is failure; d. The indoor control
board is failure
The failure for Indoor
grounding protective
The indoor control board is failure
a. It is normally for protection,When the
indoor pipe temperature below T<-1℃(-7℃).Outdoor fan motor and
compressor will stop running. When the Indoor pipe temperature is
higher than -1(-7℃),the unit will restart normally
b. The indoor coil temperature sensor is loose;
c. The indoor coil temperature sensor is failure;
d. The indoor control board is failure.
a. It is normally for protection, When the
indoor pipe temperature between 53℃<T<63℃, the outdoor fan
motor will stop running. When the indoor coil temperature is higher
than 63℃, the error code will display. After the indoor pipe
temperature is lower than 49℃, the air conditioner will restart
normally.
b. The indoor coil temperature sensor is loose;
c. The indoor coil temperature sensor is failure;
d. The indoor control board is failure.
Remark:
The failure is detected when the room temperature sensor broken or shorted over 5 sec.
The failure is detected when the temperature sensor of heater exchange broken orshorted over 5 sec.
The failure is detected when each setting data is not match after the EEPPOM self-check twotimes.
The failure is occur when the grounding signal is not detected after the appliance power ON.
