GFCIs are not used on refrigerators for same reasons you have suffered.

GFCIs can be surge damaged if proper 'whole house' protection is not installed. So newer GFCIs will trip open on power loss. And will not reset if surge damaged. That is a problem for you.

So many have posted myths. For example, any ground fault before that GFCI is completely irrelevant. The only relevant ground fault is after the GFCI. AFGIs and GFCIs do not 'fight' - another myth based in not understanding what these devices do. GFCIs do nothing for surges - for so many obvious reasons.

A GFCI measures an electromagnetic field around both wires. Obviously, this causes no power changed or problems. If those fields are not same, then a GFCI opens. IOW if current after the GFCI finds some other path to earth, then GFCI trips.

This is considered a major human safety problem for refrigerators. Therefore GFCIs are exempted on appliances that cause safety problems when tripped.
