Re: Dud Hygena/MFI fridge-freezer
There is no thermostat as such in this model as it is controlled electronically.
The £150 estimate you were given is correct as the control pcb is £118 inc VAT just for the part from MFI. The part however can be obtained from the manufacturer, Brandt for about £80 inc VAT.
That should give you some idea of possible costs, best to ask an engineer to attend though as we are only assuming that the pcb is at fault.
