Good glue to withstand heat and weight?

Hello everyone! I’m having an issue where the front panel of my dometic fridge keeps sliding down. It’s no harm to anything other than one extra layer of insulation. I tried some heavy duty double sided tape that is supposed to hold 20 lbs per whatever small square strip of it. Didn’t work. Figured the 5 pieces I used was not enough so doubled the amount. Just picked up my rv from storage and it had slid again (this was after several camping trips with additional tape. So I’m guessing I need to find some kind of glue that will withstand summer heat in South Carolina and apply a generous amount to the back and to the sides where the panel inserts into the plastic side frames of the door of the fridge. Any suggestions on a glue that will work to hold that front panel in place? Thanks!
