Troubleshooting
BY MEANS OF DIAGNOSTIC FLOW CHART :
Generally, there are two kinds of problems, i.e. starting failure and insuffi cient cooling/heating. “Starting failure”
is caused by electrical defect while improper application or defects in refrigerant circuit causes “Insuffi cient
cooling / heating”.
i) Diagnosis of Electric Circuit
