Hi, I'm Ana. I have a Bosch freezer that works perfectly, but after 3 weeks of being plugged in, the high temperature alarm starts to jump and it doesn't go back even if I put the super function on, so that the food is defrosted. The case that if I turn it off and leave it 2 days off, plugging it in again works perfectly for another 3 weeks, and so on. What could be your problem, thermostat, compressor? What I never see is water in the tank or ice anywhere, nor does it lose water, etc. I called a technician and he told me that I didn't know for sure what it could be and that it could be an expensive repair. Total that for fear that I would not compensate I did not accept the budget, in quotes, because I think it was a pirate who just took my money and did not even know where to move, but of course I feel sorry that it is something not very expensive and to be able to repair it and the truth that I wanted to call more technicians; Let's see if someone could help me, thank you very much, in advance.

The defrost system should be checked to see if it is working properly since it says that for three days the refrigerator cools well and then loses temperature. Make the controls that NG indicated online and comment the results. Regards
