Tripping Ground Fault Circuit Interrupter

So I cooked some spare ribs last week with no issues. Today I went to cook some pork chops. I set the temp as always and everything was fine. Hit the start button and GFCI tripped. Tried several times with same result. Moved to a room with a different GFCI, same results. Unit is about 3 years old. Any suggestions?
