No matter how good you are at darts, you get bounce outs when you hit the wires.

Home recreation stores sell thick rubber mats to put down.

Refrigerators should be on their own dedicated circuit.

My guess is that, as your fridge has gotten older, it is drawing more power when the compressor kicks on that it used to.

It is also entirely possible that the fridge compressor has developed a legit ground fault that needs to be addressed.

The first step is unplugging or shutting off everything else in that circuit and leave it off to see if the fridge alone will trip the GFI.

One other question: are you plugging anything at all into the GFI outlet? How about the switched outlet?

Yes. If the box is grounded either through conduit or older wiring. You can check by installing a two to three adapter, making sure to put the screw through the tab, and then use a "circuit analyzer", also called an outlet tester, to see if there is a ground.
