Re: Hoover HNMF 2605A L Fridge / Freezer.
I think the sensor may be foamed in on this Model.
If you turn the control Knob to off and the fridge continues to run it will be a module fault.
If it turns off then it is the sensor faulty.
The module may be obsolete now but you can get an alternative but you have to break off a part of he PCB depending what version it is.
The module normally comes with instructions.
If the module has a foamed in sensor then I would say it is ber.
Hope this helps
