    LG French door Refrigerator LFX31925 cap tube size

    Gday from Australia
    Would you guys know what size capillary tubes id need for an LG Refrigerator LFX31925?

    It has dual Evaps and I might replace both tubes
    This model is on R134a

    Thanks

    No I don't have information on that. It's probably 2 different size tubes as well.
    In a case like this I'd be pulling out my cap tube measuring tool.
    You don't squat with your spurs on.
    And you NEVER put the torches away before pressure testing.

    The thing is the fridge was on R600 but Im retrofitting it to r134
    Its a actually a different model here in Australia but that US model I can see looks exactly the same except for the input voltage .

    Ive changed the compressor to a r134 1/4 Hp Danfoss but need to change the capillary sizes .

    Does it have a linear compressor ?
    Ohh I see now you already pulled that one.

    I would be pulling out my running shoes.

    I am interested in seeing how this works out. It sounds like a really interesting project although I would have stayed with r600a because it really is good stuff.

    Did you bypass the electronics that control the compressor? If so what about the valve that controls which evap is cooling?
    I have thought about doing something like this but it seems extremely complicated.

    I did try and use the r600 but had heaps of r134 and welding on the system with any r600 I was a bit nervous

    Na not hard at all , just put a relay in to control the compressor when the condenser fan cuts in .
