12.1.1 Servicing freezer
(1)Check the whole circuit of freezer, if there are wire connections
came off, any wires broken, or a short circuit.
(2) Check the insulation of the whole freezer. At normal situation,
the resistance is greater than 2 mebohms; if it is less than 2
mebohms, please make a further check of the freezer 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 freezer
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 freezer will not have any
electrical problem and you can switch power on for further
completely check.
