The following information is based on your ability to use a multimeter
either to check olms or voltage, and is for a Whirlpool dryer with the
removable rear panel and the element in the rear. This type of dryer
has the lint screen on the top of the dryer.

1. Set your meter to volts and check for 240 at the outlet. Remove
plug and check prongs of pigtail to make sure they are not burned.
Leave dryer unplugged.
2. Remove rear panel, check connections of pigtail at terminal block.
3. Set your meter to ohms. Check for about 20 ohms on terminals for
the element. This reading is based on 5200 watt element. You can do
the math: watts/volts=ohms. Also, check for continuity from the
element terminals to the element housing. Reading should be very high.

4. Check for continuity on all thermostats and thermal fuses back
there. Reading should be around zero or .1 ohms.
5. Change any component that doesn't show proper reading.

This is based on most common reasons for no-heat problem. There are
more exotic answers to the problem, such as timer contacts, but this is
the simpler side of things. It also does not give you ideas about how
to keep the problem from happening again.
