9.1 Troubleshooting for Normal Malfunction
The remote controller does not receive signals (after it is powered, the buzzer will sound, unless it has malfunction)
Trip of breaker or
blow of fuse
Air conditioner can not
start up
Measure insulation resistance
to ground to see if there is any
leakage.
The circuit or the part of the air conditioner has malfunction. They heat and break the insula­tion and lead to short circuit or creepage. Measure the insula­tion resistance or eliminate the malfunction one by one. If the breaker itself has malfunction, then replace the breaker.
The transformer connection is loose or has bad c ontact or the transformer has malfunction.
Fasten the wiring; measure the output voltage of the trans­former , if it is incorrect, change the transformer.
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.
Fuse of controller burnt out
The air condi­tioner does not react after it is powered ( after the plug is inserted, the buzzer does not sound and the remote startup has no response)
Remote controller malfunction
Receiver loose or poor connection
Receiver is broken
Change controller fuse
Controller is broken
Check remote controller
Remote controller is short of power
Change batteries
First, press the manual switch button AUTO,if there is no response,check based on the above methods. If it runs nor­mally after pressing the button, check again whether the instal­lation position and the connec­tion wire of the reception head is correct. If it is correct,then re­place the receiver or the remote controller.
Power voltage is too low
Check the voltage. If it is lower than 10% of the rated voltage, check the cause, improve the power supply condition and add the sta-
bilized voltage power supply.
