Friends. As the title says, my refrigerator is advancing about an hour every two days. It is enough. Do you use an internal battery for a clock oscillator or do you sample the line frequency to set the clock? It is the 6th sense with digital panel and water dispenser. In itself, it works perfectly. You only have this clock time problem. I think that this did not happen before, so my query if it has an internal battery or something similar. Thank you all.
