3k. Electrical fault - compressor
Remove the start relay from the compressor and use an ohmmeter to test the compressor head
and start recovery. Connect ohmmeter between the common connector and start winding, then the
winding is to debug. See the picture below.
Dimensions of the compressor connections to determine whether driving and startwinding are intact.
This is done by measuring the resistance of these. Carry out three resistance measurements on
compressor penetrations. The sum of the two smallest measurements, the intact windings will be

By measuring the compressors with built winding protector it
is extremely important to measure between K and S, as this
measure will tell if this is burnt windings or an open winding
protector.
Since it is relatively small value to be measured, it would be
a great advantage to use a digital ohm-meter.
Indicates the measurement error, the compressor is replaced.
