4 things to test on a dryer
What happens here
With the dryer safely unplugged from the wall outlet, locate the thermal fuse. This is typically a small, white, rectangular component often found mounted near the heating element or the blower housing. Set your multimeter to the continuity setting (this is often indicated by a speaker icon or a diode symbol, and it will produce an audible beep when continuity is detected). Touch one probe of the multimeter to each terminal of the thermal fuse. If the multimeter beeps, the thermal fuse has continuity and is functioning correctly. If there is no beep and the multimeter displays "OL" (Open Loop), it means the fuse is blown and needs to be replaced. A blown thermal fuse frequently indicates an overheating issue, commonly caused by a clogged dryer vent.
Goal: Determine if the thermal fuse is functional
