Refrigerator Model:HBC-70/200（India） MAINTENANCE SERVICE AND TROUBLE SHOOTING 12.1 System Trouble shooting 12.1.1 Servicing refrigerator (1)Check the whole circuit of refrigerator, if there are wire connections came off, any wires broken, or a short circuit. (2) Check the insulation of the whole refrigerator. At normal situation, the resistance is greater than 2 mebohms; if it is less than 2 mebohms, please make a further check of the refrigerator resistance. Set the voltmeter to R1 Ohm position, put the two voltmeter leads pencils into L and N terminals respectively, watch the indication of odometer. The normal value is several Ohm to tens of ohm. If the resistance is zero, means that there is a short in the refrigerator circuit or there is a short caused by a bad compressor or fan motor. The reason should be found out and repaired. If the resistance is too big or infinite, this means that there is broken circuit, please check and solve it. After the above checks, the refrigerator will not have any electrical problem and you can switch power on for further completely check. １５ PDF created with pdfFactory trial version www.pdffactory.com

MAINTENANCE SERVICE AND TROUBLE SHOOTING
12.1 System Trouble shooting
12.1.1 Servicing refrigerator
(1)Check the whole circuit of refrigerator, if there are wire
connections came off, any wires broken, or a short circuit.
(2) Check the insulation of the whole refrigerator. At normal
situation, the resistance is greater than 2 mebohms; if it is less
than 2 mebohms, please make a further check of the refrigerator
resistance. Set the voltmeter to R1 Ohm position, put the two
voltmeter leads pencils into L and N terminals respectively, watch
the indication of odometer. The normal value is several Ohm to
tens of ohm. If the resistance is zero, means that there is a short
in the refrigerator circuit or there is a short caused by a bad
compressor or fan motor. The reason should be found out and
repaired. If the resistance is too big or infinite, this means that
there is broken circuit, please check and solve it.
After the above checks, the refrigerator will not have any
electrical problem and you can switch power on for further
completely check.
