I did the 120x120v / 325w calculation and it comes out to 44.3, so the 45.5 resistance is good or outside the limits ?
The resistance is reasonable. The problem when the GFCI trips is not that the element is shorted or open across its leads, but rather that the electrical insulation between it and the fridge chassis has broken down and leaks current. It needs replacement.
X2 GFCIs do go bad so replacement is another option.
Plug the refer into an extension cord and then into a pedestal GFCI if that doesn't trip then it's likely to be your GFCI.
