Re: bosch KAN58A40GB/07 freezer not freezing
i dont usually do domestic but block of ice on the evap coil sounds like a defrost problem (check heaters/defrost settings). Is the temp sensor/ probe in the evap coil or surrounded by ice? if so it would explain why your getting a reading of -18 on the display. Another possibility is that temp sensor/probe is out of calibration causing freezer to run all day long causing evap coil to ice up, is evap fan running?

Re: bosch KAN58A40GB/07 freezer not freezing
no evap fan running just pulled it out and i cant get a reading off it with my mutimeter , its all over the place on the scale goes to o/l and back to 58 ohms and back to o/l constantly thats with the fan stationary its a 13v dc motor so i presume same rules apply when checking for earth leakage and comtinuity through the control wires
