    My fridge/freezer (Samsung SR-L3928B) intermittently goes off then comes back on by itself, When this happens I hear bleeping.

    When it is off there is no display and no light inside the fridge. When it comes back on the disply shows ‘–‘ and the light comes on in the fridge.

    If I press a few buttons, i.e. Freezer, Ref, Eco then the temperature shows or Eco shows. They usually flash but sometimes they are static. When it comes back on it is okay and then could work for a few days before the same thing happens but usually this occurs every day.

    I have had the control PCB out to check connections and it looks okay. To me it appears to be the PCB that is causing the problem but I would appreciate any guidance available.

    If it needs a new PCB then suggestions as to where and how much would also be helpful.

    HI

    Check your defrost heater.

    We are having exactly the same problem. It occurred a few months ago but rectified itself after a couple of days just when I was going to call someone out, now it has returned.
    How do I tell if it is the defrost heater that is at fault?

    I went with the advice and bought a Defrost Heater. Unfortunately, after taking panels off: lower back outside, fridge inner rear, freezer rear and control panel top outside, I could not find where the Defrost Heater is located.

    Does anyone have any idea where I can find it?

    When I said ‘Freezer rear’ I meant the lower back inside. I couldn’t find anything there other than some cables at left and no further access into anything else that may be ‘hidden’.

    If the Defrost Heater is definitely on the sinde at the back of the freezer I will have a look again.
