I’ve inherited a bosch classixx kgu30605 fridge freezer that’s not working. Turning it on it comes to life briefly, including whirring sounds from the compressor and then after half a minute a click sound comes from a relay-type-plastic box (not the danfloss relay attached to side of compressor which has been checked and seems fine), inside which is what looks like a cylindrical (relay?) which has copper pipes making contact with it. The unit turns off at this point, then the relay-type-box immediately clicks again and it begins to start up again and cycles through this process over and over without cooling the fridge or freezer. This cylindrical (relay?) is connected to brown and blue wires fed down from the above, not (seemingly) from the mains.
Does anyone know what this part is and if replacing it might fix my problem?
Also the temperature light on the front of the fridge freezer show red (indicating the thermostat knows it is too warm and is working?). No clicking noises from the top of fridge either.
Many thanks
