Hi @mostelectorlux ,
In the link you posted, there are two parts that may be of interest.
Click on Cooling System 017, then Please select a number, part #11 the running capacitor and also part #8 the starting device with motor protector part.
When the motor is initially started it operates on the start and run windings. When it gets up to speed an internal centrifugal switch operates and disconnects the start winding as the motor can continue to operate on the run winding only. The start winding is only used to help overcome the inertia of the motor from the at rest position. If the capacitor is faulty then it can’t continue to run and it will stop and then try to start again etc.
Is the compressor motor getting too hot to touch even in the short time that it is on?
They are designed to be able to run continuously for long periods so it can be warm but not too hot to touch. If the capacitor is faulty then the motor might be getting too hot as there is a lot of current flowing when both windings are being used. If so, then the protector is just doing what it is designed to do and turning it off.
It could also simply be that the starter/protector is faulty and cutting out when it shouldn’t.
Worst case is that it may be that the compressor is faulty or perhaps there has been a loss of refrigerant from the sealed cooling system. Check for any oily residues on the condenser coils or on or under the compressor motor. There is a special oil mixed in with the refrigerant to lubricate the compressor. If there is a leak, then the refrigerant will escape to the air undetected but the oil may leave a trace.
Depending on your location, you may need a licensed fridge repairer to check the sealed system and compressor etc so as to comply with the government’s environmental regulations regarding the handling of refrigerant gases.
