Miele Fridge Freezer not cooling Please Help

jmsa7

Hello,

My Miele Fridge Freezer stopped cooling following a storm causing an electrical surge that also damaged other appliances. Everything else works fine like lights, fans, touchscreen control unit but seems like compressor is not running.

I found some swollen capacitors in the control unit which were replaced but didn't fix the problem.

There is an Embraco VES Inverter unit next to the compressor and 2 cables connected to it. I can confirm 240V going to Inverter and the other cable has 3 wires which come from the control unit and are labelled TX, RX and Gnd. I believe the compressor is being controlled with some kind of serial communication, maybe RS232.

Is there a way of checking that the inverter is receiving the right signals?

I would also like to check and maybe replace the inverter unit as I believe it might be faulty but can't figure out how to take out and the compressor pipework is blocking it. Please see photo attached.
