An internet search said it was either the fuse or the igniter. Since the dryer was 17 years old we figured it was time to replace both. APP made finding the right parts for our model super easy and even included a video of how to replace that part on the part page. How convenient! We got the job done in about 20 minutes, 4 days ahead of the earliest time a repair man could come look at it. So nice to be wearing clean clothes again!
