Please i am working on a samsung Refrigerator which had a problem with the compressor(inverter type). There was a similar working samsung refrigerator (different model) so the Mechanic i was working with swap the compressors but did not work. l tried checking the voltage at all the three terminals f eeding the compressor but no voltage (both ac and dc). surprisingly when we fixed another compressor from the same model it worked. What i don't under stand is how will the compressor work when no voltage is present? The compr essor has three pins which reads 14 ohms all round. Please i will be very h appy if the expects here can explain things to me. Thanks in advance.
