Kenmore Coldspot trips GFI, Occasionally

Hello all-

We bought a new fridge and moved the old one to the garage. Everything worked fine.

Then it started to trip the GFI. It will trip as soon as I plug it in, sometimes. Other times it runs for hours and trips the switch. I’ve tried it at another outlet with the same results.

When it starts on it cools/freezes fine.

Right now I am befuddled and can not think about it logically.

Does anyone have new ideas?

Thanks
Charles
