GFI issue in bathroom -trips 3 recptaces - will not reset

I had s similar situation. Took MH (97 Coachmen F-53) in for refridgerator recall and explained to tech what was happening with GFI. He knew where to look right away and solved the problem by replacing a rod that goes to fridge. The rod gets super hot and how that works on a fridge is beyond me. I was just amazed and happy that he got it fixed so quickly.
