Connecting/"shorting" the temp sensor connector "T" and "C" on the pump circuit used to make the compressor start up and it would cool down (which ended up as a workaround for the last year or so and delayed me fixing it properly as effectively it worked in a way that was fine for our short trips), but this no longer does anything. Instead the controller makes a faint noise for 3-4 secs when connecting connectors T & C then nothing. The fuse inside the controller is intact and the fridge has power. On the Westfalia control panel when turning on the fridge the snowflake symbol flashes to indicate a fridge problem (which it has done since it first had a problem).
