Likely not the grid. The grid is pretty solid. I will guess it is the
wave traps seals arround the microwave door (often they are made
rubber part mixed with conductive stuff) that are too old. These seals
tend to expand when hot and are therefore more efficient. You could
change it for cheap ($10), ask our local general store. As a quick fix
(not recommended) you could add some electrical conductive grease but
it will further decreade long term abilty of these seals (grease tend
to crack rubber), and these kind of grease are not really food
compatible.
