It is usually on the other side of the control knob you use to adjust the temperature.

Thanks but this fridge freezer has an electronic temperature control.ler. The external control dial (accessable from outside the fride/freezer) is at the very top of the fridge compartment (mounted

Show us a picture. If it's a control dial then it's more than likely connected to a thermostat immediately behind it. I'm a little confused tbh.

If it is electronic controlled, the pcb does the switching of the compressor based on readings from a thermistor (s) in the fridge and or freezer compartments, does it have a fast freeze switch, if so have you tried it ?

Can't say as I've seen a PCB based one with a dial tbh. If it is then the thermistor is likely to be somewhere towards the rear of the fridge behind the cooling plate.

Some do its a potentiometer on the pcb you are adjusting with the control knob, the thermister is usually inside the compartment surface mounted (behind a grill or similar) so it reads air temperature rather than plate temperature for more accurate control.

I have now removed the control dial and the PCB behind it. There is a

Thanks everone for your suggestions.

The fast freeze button doesn't turn on the compressor when pressed in.

Is it likely that a triac is used to switch on and off the compressor?
