if its leaked it finished if it hasnt leaked but stopped working you can try turning it upside down fow a few hours

No not leaked have turned it upside down it’s is working for now but been told it will block again just trying to sort it for peace of mind domestic don’t make replacement without a bit of woodwork

The cooling circuit contains a mixture of gas and liquid, and it has to be just the right quantity of each, for each different fridge model. It's not as simple as the re-gas process for a compressor fridge. There's a place in the US that does it, and I seem to remember someone on this forum mentioned someone he knows in the UK who can do it. So it's possible, in theory, but I'd say it's impossible in practice.

I think it's possible to buy the complete cooling circuit as a spare part, but I don't know where from.

I had one replaced in an R-V back in the 90`s. But I know for a fact the guy retired years ago. The only places I know of are R-V related and based in the USA. By the time you have sourced and had it fitted. I would think you are within pennies of a brand new one.

I would be better tempted to bite on the bullet, fit a New one and get a good Carpenter to build some nice polished wood surrounds?.

If my understanding is correct it doesn't get blocked.
The cooling fluid and gas, which must be in a suspension, eventually separate out and turning it upside down remixes the fluid with the gas as the fluid drains to the lowest point.
Maybe turning it a few times may have an even longer lasting effect.

The correct way, is to turn in the direction of the coil on the rear of the unit, and keep turning until you are satisfied the Liquid/gases have returned to the heat source, often 3 or 4 full turns!.

Back in the dark ages. We had fridges on ships using the same system as they did not have models which operated at 110V DC. They where the size of a modern fridge freezer and turning them needed a set of 1/2 ton Chain Blocks!! and large webbing strops.
