an older more discerning machine ,wont switch off,compressor runs constantly .Now what i want to know is how does the fridge part of the machine cool ? i just about understand the refrigeration process and have taken the temp of the fridge which is not getting below 8c ,the freezer is thick with ice and am currently defrosting .Its an old banger about 20 year old ,ready to chuck it but i think it is repairable maybe . 
What i want to know is  how does the fridge part cool ? 
Does the cold air just waft up from below ?  could a lot of ice actually prevent this process ?
also what does the "super" switch do ?  and could this be part of the prob ?  think super just increases the temp of the freezer but could the freezers gain be the fridges loss in the mode ?

cheers .

lol i think youre being a bit optimistic!

now if youd asked for experts on immigration, farting or pies youd be odds-on asking the chitchat muggs! Laugh

I started to reply, but it should be much easier and clearer for you just to Google 'refrigerator'. Happy

SIDESHOW ....beat it ...i need help Laugh

i am not being optimistic ,everything is repairable ,i just need some basic info .

i need a fridge dude .

Google 'refrigertor' or 'refrigeration circuitry'...it's all there on the other side of your keyboard.

Switch off, turn upside down for 24 hours, stand up, plug in, and you may have a good fridge or a **** one, gl.

so how does the fridge cool ? it does not cool off the refrigeration circuit imo ,metal plate at the back behind a panel ? ducting a void ?

liam your blocked bud ,once the decision has been made its irreversible so your wasting your time on this one .

thats not very fookin friendly now is it!

i was only trying to help ffs.

well, i wasnt trying to help really, but... ok i get ya point Laugh

seriously though ive wondered this myself. my fridge bit gets too cold, gets ice in it.
the ice starts around a hole in the fridge that i presumed was to drain condensation. seeing as its this bit that gets ice, maybe that hole is where cold air enters from the freezer bit??

It works on the physical fact that gasses cool when they expand, and heat up when compressed. You fridge has a closed circuit where the cooling/expanding gas circuit INSIDE the fridge and the hot/compressed gasses are OUTSIDE the fridge and dissipate their heat out of the back of the fridge. Google it. It should be clear. Happy

nawe thats to drain the condensation panel ,it deposits the H2o on a pan on top of the  compressor and it condensates away due to the heat from said compressor .The ice monster in the fridge is not the issue here sideshow ,would love a bit of ice in there .although it does ice at the bottom corners occasionally .

i understand the refrigeration process Naydam but thats NOT how the fridge works you ****

the fridge not the freezer ,the fridge is not piped imo ,but unsure

the fridge is staying above 8c but freezer is -20

think there is either a metal plate or ducting which may be frozen with ice and preventing enough surface area being in play but i dont really know .i will if i have to strip the bastid to bits Wink

stat is in fridge hence compressor runs constantly .

should be below 5c

Naydam has explained the physics perfectly.
All the ice build up is insulating the cooling surfaces inside the fridge so it doesn't cool enough for the thermostat to switch off the compressor, which is why it runs continuously.
First thing to do is defrost it completely and sop up the water then make sure that the drainage hole is unblocked. You can probably do that with a pipe cleaner. Make sure that there is good air circulation around the external radiator panel and site it away from any sources of heat if possible.

Well, I Googled '****' but they couldn't help. It just said 'No documents were found'. Sad

You could try Googling 'Freezer icing up'...there are some posts on there about it. With 'fridge not cool', too. Happy

the drainage hole is nether here nor there and has nothing to do with the fridge not cooling,it allows the condensation to escape and helps keep ice out of the fridge .

a drop of washing up liquid keeps the drainage hole clear .

You are saying the ice in the freezer is insulating the fridge ,just that it has a "super" switch and this decreases the temp of the freezer and on some it closes flaps and sh1t so think this may be the problem ,hopefully the defrost will do the job .

sorry Naydam ...it was a slip of the fingers ...apologies
a know you are trying to help ,just a hate asking for help to be told what i already explained i already understand .Wink

the freezing circuit is A1 its a big upright ,they dont use that circuit directly to cool the fridge they use either metal plates or ducting but unsure about this one ,some have a flap operated by a wee motor/solonoid some have fans ,but i am unsure about that side of things hence the question .

Good luck breadnbutter. Used to have similar problems with my old fridge-freezer and eventually got fed up and bought a new Samsung. This is a much better design and there's no ice or condensation anywhere after two years continuous running.

yea TBH i defrosted with the intention of taking the thing out the back and giving it a good hiding with a sledge hammer but then started to think it may be savable ,the technology has moved on a bit and really need a new one  ,the american machines are probably the best as they are made for warmer climate but you can spend as much as you have got on a good one .Samsung good for electronics but not sure about their fridges and freezers .

Separate units will be the way ahead if i renew
