Dumb question I’m assuming dollar bill test is close doors, griddle, ash pan... see if dollar bill is removable from test spot? Testing sections of gasket.
Searched for this test.
Yes. Close the griddle with the bill (or piece of paper) 1/2 way in, then try to pull it out. If it comes out easily then the gasket failed the test. If you cannot move the bill, then it is a good sign. Move say 5” further and repeat. Same for the doors and ashpan
