Hi
Just returned from my son’s house and his Hotpoint FF72 is completely dead – no lights – no sound.
I’ve checked that power reaches the junction box on the compressor but don’t know where to start looking for the fault.
I’ve searched this forum but have been unable to find any suitable advice.
Any guidance to finding the fault would be greatly appreciated.
Many thanks
Re: Hotpoint Fridge Freezer FF72 completely dead
Check if power is arriving on the control PCB in the top of the unit.
To gain access open the fridge door and release the three recessed cross-head screws that hold the control/display panel in place.
Lift the panel front edge and pull forward and up.
If the PCB has “Procond” on it you will see there are two edge-connectors on the right, one with the two leads, the other with six.
On the connector with six leads, counting from the *back* of the board is pin 1. AC live is on pin 6, neutral on pin 5.
These come directly from the compressor terminals via the three-way connector (leads coloured white, red, blue) that plugs into a socket in the base of the rear cabinet.
If you’re sticking multimedia prongs into the controller PCB connector be aware that you can think you’ve got a good electrical contact but in fact not have any, so you might need slim prongs and wiggle them about a bit.

Hi feefifofum
Thanks for your reply. As I will not be at my son’s for a few days it would be useful to know what the next step is assuming that there is power to the PCB.
Would this mean that the PCB is faulty if so are they repairable? Is there a particular component that fails and can this be replaced cheaply? Both my son and I are qualified electronics engineers.
Many thanks
Doug
Re: Hotpoint Fridge Freezer FF72 completely dead
The control PCB is pretty straightforward; if you’re an electronics engineer you’ll easily be able to decompose the circuit in your head.
One thing I misled you on. The three-way connector in the base of the rear cabinet is wired into the freezer compartment. There are two thermal fuses, one each in the live and neutral circuits, clipped to the right-top of the evaporator.
You should be able to trace the terminal connections from them up to the control PCB and back to the compressor using a continuity test, too.
