My Bosch upright freezer motor runs and gets hot, but the appliance does not freeze inside. What could the trouble be??

I would suggest either the coolant has partially escaped and needs re-pressurising or the compressor is damaged. Both of these faults would result in the motor overheating and both would need the attention of a service engineer.

The freezer alarm won't go off.

Possibly a problem with one of the components in the automatic defrost system in the freezer then.. this is the only reason why the alarm would keep sounding. Perhaps some of the moisture from the defrost has gotten in and damaged the electricals somehow. It might be worth it to store your freezer contents elsewhere and completely defrost the freezer and then heat the inside cabinet up with a hair dryer or something similar. This will dry out the cabinet and the electrical components. Once the freezer has warmed up let it stand for as long as possible with the doors open so that it reaches room temperature and then close the doors and switch back on. If this doesn't work you probably need a service engineer visit.

Fault in the controller board as it must be tripping off the alarm without the sensor giving the signal.
You will need to check the conttroller board for sorting out , other wise just disconnect the alarm as the freezer working and the thermostat is controlling the temperature correctly

Bosch fridge freezer stops working after approx 8 hours. Starts OK and freezes OK but next day it's warming up. Turn it off and back on again and it starts all over again and the problem reoccurs..

Found a solution at

Short out the dark blue and the dark brown wires that lead into the temp control dial. Everything now works. This bipasses a dodgy thermister or something. Of course this might not solve all similar problems but it does seem a common fault.
