Hi all, i have a problem with a Lg (GR~B207GUQA) Side by side fridge freezer, the problem is the freezer wont go down to -20c, I think the compressor may be shot as it stays on all the time to try and get it down to -20c but only manages -12c then must cut out because it then gose back to 0c and then try's again.

I dont know a deal about theses appliances as i repair washers/dryers cookers etc.etc... The compressor dose get hot, the fan cooling the condensor is running and ive removed all the dust from the fins, the appliance is just 3yrs old and has had no problems up till now. Ive tried the test function button on the power board but it shows no errors.

On the Uk site i go on ive been told it may well be the compressor thats worn and giving low preasure.
any help would be great as i can see me putting it on ebay if i calnt find the problem.
