Frost-free freezer "modification"
VanMarco:
HELLO!
I bought a freezer today at the usual store that sell used/refurbished ones. here where i live there are many shops that import appliances from Germany and fix it and resell it. I have already bought 4 from them, unfortunately one died recently and i needed urgently another one.
I didn't want to buy another 25 years old one, even though very reliable, the gasket can be ruined.
They had some nice frost-free ones, but, none, the electronic board worked. The price was quite low though, so I bought one.
They call these "modified". Essentially, the electronic board that controls the freezer is faulty, so they simply bypassed it, using a regular mechanical thermostat (which I plan to replace with a nice electronic one with numbers and all) and a defrost timer.
Now for me it does not matter if the board is not working anymore, but am I going to encounter any issues or downside of this mod?
Thank you in advance.

The electronics are unnecessary for a fridge or freezer to perform its functions, as the older models didn't have any. A bimetallic thermostat and mechanical defrost timer should work fine and are much more reliable.
VanMarco:
ah thanks, i also figure that in theory it would be better, as those parts they used, are simple and common to find a replacement for, my other miele freezer got faulty, the part costed 40 euro :( yes, a simple ptc probe.
sorry for the weird question, i bought based on general condition, gasket is new :)
thankssss

You can check that the condensor coils are getting hot and the inside and outside fans are running, and that the compressor pump starts smoothly. That pretty much covers the mechanical aspects.
If the compressor's start capacitor is weak it may not start smoothly. Replacing the capacitor (or replacing it with a higher value) is very simple.

Agreed; a mechanical thermostat has far less to go wrong, and when it does, is also much easier to fix. A lot of fridges from the pre-electronics era are still working perfectly well today.
