As far as I know, modern appliances use gasses without this problem. It also holds for fridges.

As far as I know, gases that cause holes in the ozone layer aren't used anymore, but they're still extremely strong greenhouse gases (recent newspaper article I read mentioned 2000x CO2).

There is a move to more environmentally friendly gasses, but the new gasses are still in the hundreds of times Co2 equivalent (Down from thousands)

  How can I find out if my fridge uses R410A?

Modern refrigerators usually use a refrigerant called HFC-134a (1,1,1,2-Tetrafluoroethane), which does not deplete the ozone layer, unlike Freon. R-134a is becoming much rarer in Europe.
