Judith P Warren , VT June 27, 2019 Dryer heating but not shutting off, timer stopped before triggering shut off Replaced timer. Didn’t change anything. Paid $25 to get help from Appliance Pro. He first suggested replacing the heat sensor. That didn’t make sense. We talked further and decided the PC board was the culprit. I replaced that today. Hooray, it works. Spent about $170 solving the problem Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
