Check the circuit breakers for the dryer to make sure that one is not tripped. Some houses have fuses for the dryer. Check the house fuses for the dryer outlet if your home has these. This basic troubleshooting step should not be overlooked. The dryer will run if only one of the 120 volt legs of 240 volt electrical power is supplied to the dryer (traced in red on the wiring diagram below). If the second leg of 120 volt power (traced in green) is missing, the dryer will not heat.
If the breakers (or fuses) are okay, then you could have a problem with the dryer outlet. If you have a volt/ohm meter, you can carefully check the voltage at the outlet using the diagram in the second image. NOTE: You should only check this live outlet voltage if you are completely confident in your technical ability to safely measure it.
You could have bad heating element. The link for a previous answer that Barbara provided shows how to check that component with a volt/ohm meter.
Unplug the dryer
and remove the back panel of the dryer to access the heating element.
If the heating element is okay, you could have one of these failures:
Open high limit thermostat
Failed operating thermostat
Blown thermal cut-off fuse
Bad timer switch #2
Failed motor centrifugal switch
Wiring failure in the circuit
The third image below shows a drawing with the location of some components in the heating system of this dryer. You can check the first 3 components in the above list using a volt/ohm meter. With the dryer
, measure the resistance through these components. They should all measure near zero ohms of resistance. If any component is "open" (measure Ol -- open load or infinite resistance) then it will need to be replaced.
If the thermal cut-off fuse is blown, you will need to replace the high limit thermostat and the operating thermostat at the same time since these components should have "opened" to prevent the fuse from blowing.

These tips may help you determine the cause of your heating failure in the dryer.
