Since my last post, I have guessed that the two ISPRA Black switches are in fact probably fuses in series with the heating element (one on the live and one on the neutral) Both appear to be ok. The heating element impedance is approx 3.5kOhm (The fact that there is continuity suggests the element is ok)

There is a thermistor which lies behind the freezer coils it also measures about 3-4 kOhms I would think this is ok (I had expected this to be a thermostat either open or closed but it seems that this thermistor must control a switch on the electronic board – how I wish I had a schematic for this). My thoughts are if the heating element impedance appears ok then the electronic board/timer has gone faulty.

I would appreciate your on how to assess further and how much a new electronic board/defrost timer unit would be.

Thanks

Re: MFI APM6855 Fridge Problem

Hi all 😀

Seems like a common problem with the APM6855, likewise my fridge stopped cooling yesterday (Hottest Day of the year nearly) but the freezer was ok and it too is only 13 months old.

I prised out the plastic cover at the back of the freezer compartment and pulled forward the freezing element cover that houses the circulation fan to find that there was quite a bit of ice surrounding the element.

I switched off the fridge/freezer completely, defrosted it overnight, started it up again this morning and it is now running great again. I am unsure if there is an underlying fault with a heating circuit which should reduce the ice build up surrounding the element. I’ll check the element again in the next few months.

I was thinking that the problem lay with a faulty thermostat initially as well, I’m glad I read this thread first.

Thanks, Mystick
