PM Clipperjay, he's quite good with freezing things to near absolute zero. You never know maybe an easy fix.

Looks like short of gas or dryer could be partialy blocked need to stick gauges to check pressures TBH
When there is not enough gas it boils off quicker and starts to freeze on closest coils i.e not enough liquid refrigerant going through show me better pictures of whole system?

hi thanks for reply, i cant work out how to take rest out i.e condensers i not great with things like this what parts did you mean to take pics off. will it be damaged if ran getting frozen, i didnt relise was freezing at first. there was a small cylinder about 2cm thick at top of right side getting frozen too. I used the fan loads since last summer to sleep as white noise maybe it full dust further in grills or inside, its one them homebase ones cheers

Okay simple system to me, Its something you can't fix TBF, but best option would be to find a good A/C man to help out they usually charge about £50 call out and insist on a nitrogen leak test there is a reason why its loosing gas usually from valve ports.
The ice is no problem its the leak that important.
Who ever you hire to take the job on make sure they
Nitrogen Oxygen Free (Pressure test) 
Use a VAC pump to take air and moisture out.
Change the sausage looking item made from copper its called a Spun drier!
Regass R134a
If the leak is on the (heater matrix (rads) looking parts) it might not be worth fixing!
Anywhere there is copper and valves can be braised/replaced to plug up the leak!
I would charge roughly £150 you might get charged more though dark arts 
You could just charge it yourself, but it won't last long depends how fast its leaking? 
Yeah £45 quid just get a new one this is a domestic jobbie I rarely touch them as I cost too much to help!   



I do freeze the odd animal and sometimes they do come back to life Honest, Cryo is a dark art

thanks a lot mate really appreciate the reply, i usually lucky with stuff it never fails, most things arnt worth fixing knowadays due to cost, i seen a few sell for 50-70 and people say hardly been used usually but never really know i guess. are these worth much as scrap? and metals in them? what could i sell it for? may ebay it, cheers i been using it as a fan lol it quite powerfull on high and only uses same as normal fan it takes up a lot of room though for a fan, they weigh like 38kg too

probably worth £20 in scrap.
