Whirlpool / Maytag Dryer Won't Start or F01 Error: Thermal Fuse (#WP3392519)
Quick Answer: When a Whirlpool, Maytag, or Kenmore dryer will not start (makes a single click when pressing Start) or stops heating, 85% of the time the disposable white Thermal Fuse (#WP3392519) on the back blower housing has blown. If the display explicitly flashes F01 or F1 E1, the main control board relay has failed.
⚠️ The $9 Part That Saves Perfectly Good Dryers From the Curb: On Whirlpool and Maytag electric dryers, a blown Thermal Fuse (#WP3392519) doesn't just cut off the heat—it cuts power to the drive motor so the dryer won't even start! Replacing this $9 stick fuse on the back panel brings a 'dead' dryer right back to life.
