7-5. Trouble Diagnosis of Electric Filter Board

   

Visual examination: as the circuit is simple, the connection may be checked visually to see whether 

any loose or poor connection. 

Voltage test: the voltage at the input end shall be the same as the voltage at the output end. 

 

7-6. Trouble Diagnosis of Electric Communication

   

 

Step one: to determine whether the connecting cables and tether cables of indoor/outdoor units are 

correctly wired. If not, change wiring order and test connection. 

Step two: to determine whether there is loose connection. 

        Fasten the connection in the case of loose connection and then conduct verification. 

Step three: measure the voltage between SI and N with multi-meter and see whether the voltage 

fluctuates between 0V and 24V. Please directly replace indoor and outdoor control boards if there are not 

voltage fluctuations.
