i need a schematic diagram of a fridge

SOURCE: I have a beko fridge freezer. I had an error code

I got the answer myself and thought I would share it.
The E4 code means that the auto defrost is not working. Call beko and tell them the code and they will tell you what part it is. I think the part number is 421445. It is a little black tube with two wires comming out. The part costs about £10. To fit the part you have to go into the feezer side of the fridge and carefully remove the white plastic at the back which is held with clips and one screw. To find where the part goes look for a long white fatish wire. The black fuse or thermostate is hidden in that. You will see where the wires go when you remove the old one. It is easy to do. Once you replace the part the error light will still be on but will go out after the fridge is back to being cold. Don't forget to replace the inside of the freezer when done! Hope this helps. John
