The warning beeper keeps going off on my old Bosch fridge-freezer, but temperature's OK. This sound is really irritating but I don't want to pay the UK £117 callout and possibly the cost of a new circuit board for what is a 20 year-old machine, when the machine is keeping temperature OK.
I have the idea of cutting off the loudspeaker but does anyone know whether this can be accessed easily behind the top panel?
The Bosch ENR is KGU32163GB.
I've replaced or disabled such piezo devices on several appliances (I don't even like that noise when it's working properly). It's usually not difficult to get access to the control board. There you can desolder or cut a leg of the buzzer. There's some risk that this will cause a fault, though. Do any modifications such that they're reversible if necessary.
Note that if your buzzer is sounding falsely there's probably more going on than you imply by your question. Obviously the temperature control circuitry is having a problem, and you risk losing or freezing food if you continue use of the refrigerator without addressing the core issue.
Note also that even a seemingly modern 20 year old refrigerator likely uses much more energy than a new one would. That may make replacement more appealing.
