By the way I am beyond the 60 days retour policy they have at cateringparts uk. The return period is 30 days from purchase.

Bummer, anyway a new one is on it's way.

Nike123, does the treshold of the ice thickness thermostat starts at - 8 C(to -15 c)?

I think I can never do a test with a piece of ice. Cause that is less then -8 C? I might be not thinking clearly now.
A piece of ice can probably be lower then -8 C.

I was thinking to use a piece of ice to test the ice thickness thermostat right away when i have it in 2 weeks. To check if the defrost cycle will kick in.
