2 wire transformer

Along with close up photo, tell us the symptoms.
Is it making noises like the compressor is trying to start?

It's doubtful that a choke is bad. More likely the overload in series with the compressor or
something external.
Take voltage readings with everything connected at terminal comp pins 1 and 5.
If it's not passing power look at something external like a thermostat or maybe even a door switch.

Btw, Your picture can be just the portion of relevance, not the entire schematic or circuit board. That way we can see details and your file size will not be too large.

There is a class action lawsuit against LG alleging their linear compressors are defective.

I am aware of the class action lawsuit. The voltage across the terminals which take power to the compressor started at 149v and rose to about 154v. Incidentally the voltage across the capacitor was only 70v rising slowly. Once the refrigerator booted up the cooling fan started as normal but there was no noise from the compressor at all. When I tested the voltage at the compressor plug with the compressor disconnected I only found 111,6v. I have left the refrigerator running for several minutes, returned to test the voltage on the circuit board output and the voltage has risen to 204v. Still no noise from the compressor but the cooling fan has become very noisy.

I have left the unit running and now the output voltage is approaching our mains voltage of 220v, and I will have to accept that the refigerator will have to be dumped, shame I have wasted money on a circuit board and solenoid valve for nothing, but being retired and on a pension I have to try to keep things going as long as possible. I won't be buying LG again, their support staff were most unhelpful and there are no LG specialists in this area and even had there been the charges would have been extortionate. I know about the class action against LG in the states but there isalso a class action against Samsung due to faults with their icemaker. It is difficult to find a maker with no negative feedbacks and I don't have $4000 to pay for a Neff. May I thank you for your valuable assistance and would you accept my apologies for wasting your time. Regards, Michael

Sorry about your luck.
If you're nearing mains voltage at the compressor terminals, its obviously bad.
The compressor runs at variable speeds which explains the odd voltages.

Too bad you replaced the board.
Measuring current is better for determining open circuit failure rather than just measuring applied voltage.

You might try asking a local repair shop before scrapping it. Who knows, perhaps they can retrofit another compressor into it?

The sad irony here is that newer appliances boast their energy savings, but it's offset by filling our landfills due to their shorter lifecycles.
