Hi Bruce my name is ***** ***** you let me have the product code usually beginning with a 3............... that is located on the rating label. Once I have this to hand I can have a look at the wiring diagram for you ~ do you have a multimeter?
Leave this with me a short while, according to my data this is not a UK model but designed for the French market. Just doing some further research.
Ok when you are ready we can proceed I have a wiring diagram but cant get the exploded views first thing I need you to do is find the main power control pcb.
OK multimeter set to measure 240v AC. Find connector CN101 and test that you have power at blue and brown cables?
Do you have voltage between blue and white on the same connector
OK looks like you need to change the board as you have no power going to the compressor and the interior light is also fed from this pcb too. If you flip the board over can you see any track damage or burn marks?
Look at the contacts where the relays go through the pcb ? As you dont have any light in the fridge when you open the door Im fairly sure this board is faulty.
Try contacting this company - www.qer.biz - they will repair it for you if you send it off.
