The mabe refrigerator with timer at startup does not turn on the unit but if I connect it with another direct cable if it turns on how I can measure each cable of the connection so that the relay and thermal power arrive

Hi Ralesme, if you can get a multimeter, verify continuity of the input cable and, if possible, of the cables inside your refrigerator, for this you have to disconnect each component, if you have continuity in all the cables, you will fail In some component, for this I leave you an address where all the information about failures and possible solutions comes, hoping it will be of great value.
