By opting out you mean you can't be of any help which leaves me none the wiser. What do I owe you for your time? Or is it 'no help, no charge'
In your intial post, did you mean that defrosting the freezer manually no longer gets it working again?
First thing is that I'm in the UK...does that make a difference?
Anyway, to answer your question, when the freezer stops working I usually apply a hotgun to the horizontal grid at the base of the plastic back panel...I don't actually get to the coils which, I assume are behind the back panel ( which I don't know how to remove). The panel seems to held in place by plastic studs which don't appear to be unscrewable!
Hope this helps.
Being in the UK is ok, I'm there too. LOL.
OK, the first thing to do is just do a manual defrost, ie, turn the machine off, 24 hours with the doors open. This will clear the evaperator in the freezer.
Turn it back on and if it starts working again then the initial post here from Bryan will be on the right lines.
There are 3 parts associated with the defrost function.
The first is the pcb, this controls everything.
The next is the defrost heater and the last the defrost thermostat.
I would suspect the heater (or thermal fuse if fitted) is open circuit.
This means it's not defrosting properly and ice builds up on the evaperator. Once this the fan is unable to circulate the cold air so the freezer gets warmer.
Carry out the manual defrost. See how it goes and let me know.
Good luck with the diagnosing.
Thanks, I'll do that and let you know what happens
Many thanks, XXXXX XXXXX worked and freezer now running OK. Nothing else seems to be wrong so I'll leave well alone!!
Just come back if the fault returns quickly.
No problem, I'll notify them what's happened.
