Here you can find the short version of my german article about the repair of my freezer (AEG ARCTIS G 8 88 50 i or 8 88 59 i) that regularly failed to turn the compressor on. So if your freezer is also regularly running into the high temperatur alert, then have a look at my instruction of repair. The reason of failure is often that the 1µF capacitor has a much too low capacity, i.e. 0.4µF in my case.
instruction of repair:
This repair requires a qualification as electrician. I do not take over any warranty or responsability for any damage that might occur!
