Dryer heats but only runs for about 30 secs

SOURCE: Dryer runs & heats but shuts off after 3-10 minutes

the motor overload can caouse that problem in that case new motor is needed if the dryer turn right back on after it turns off the even heat control board in panel bad if it humms are no noise after turn off and you have to let cool down the motor is the problem

SOURCE: Dryer heating element(s) are inconsistent

there is only 1 element. were you taking these readings with the wires on them?
the other 2 were thermostats.was there lots of lint?
sounds like you may have bad thermostat.

SOURCE: runs but does not heat

Sounds like the timer may have failed if the dryer continues to run for hours and hours. And this may be what keeps the heating elemnts from coming on.

Reply your findings and I can help you more.

SOURCE: Element heats, dryer tumbles, no heat in drum, never shuts off

Hi, If the dryer heats but will not advance in either time or auto cycles, you need to change the timer.
You can test to see if the timer is getting voltage. Remove the top rear panel and locate the two wires going to the timer motor. There should be 120V when the dryer is running in time dry.
Please let me know if this helps or if I can assist you further.

Thanks
Vic
