The Zanussi ZX77/3W(SI) fridge freezer alarms about once per month. If I reset the fridge freezer (when it alarms) by pressing down and holding the power on/off button and then turn it on the same way then the error disappears and the fridge works fine (for a few weeks).
I’ve monitored the temperature over time and it appears stable in both the fridge and freezer compartments. Also I’ve tried defrosting for a day and also cleaning the air inlet at the very bottom of the fridge, both to no avail.
Any suggestions what might be going on?
Thanks (in advance)
