YES
Check if the compressor
normal ?
YES
Check if the starting current of
compressor excess too much?
Test the resistance parameter of the compressor; if it
is
is ZERO, inner winding is short circuit. If it is
infinite, inner winding is break circuit
If all technical parameter of compressor and
compressor accessories (PTC starter, overload
protector, run capacitor) are normal after above test,
but compressor still can not be started, and overload
protector action, the actual starting current excess
too much. This phenomenon usually caused by
compressor inner mechanical failure (cylinder-block
or axis-hung problem).
