just wont dry

my dryer was wroking fine 1 day the next day wouldn’t dry. it sounds like its working, but there is no heat. I was told to change the fuse but I’m not sure where to find it. Do I have to take the big panel of the back or the little one… and I did make sure the vents were clean.

Slide out dryer and lay on its front… Remove rear large panel… look at the back the heater and heater thermal fuse are in and on the long siver box… Heater at botton with the thermostat and the fuse at the top… Remove 1 wire from fuse and check the terminals on the fuse , they shld have continuity… if not replace / if does do same on heater below, remove 1 wire to heater and check it for continuity…
