if the flame is liting most likely problem is bad air movement.go outside with thedryer running and check the hood to see how strong the air is blowing out,if there's a cage or anything blocking the hood remove it,if the vent line is a long run remove the vent line from the back of the dryer,stick a leaf blower into it and blow out the lint to the outside.also with the dryer unplugged,remove the bottom panel,remove the lint filter and metal duct the filter slides into,clean that out and blow out the blower wheel with a shop vac,you can blow out the gas tube where the flame ignites to make sure it's clean blow off the motor and the cabinet and vac up all lint that blows forwards.you can try running the dryer with the vent line removed to see if it runs any better.when the dryer first heats up the flame will come on until the temp. is reached and it will shut down,one more thing to check,when gas coils start to fail you'll have heat for like the first 15 to 30 minutes,then when the coils heat up the ignitor will glow but no flame,after the coils cool down they will work again.how are you running it on timed dry or more or less dry,if you run it on auto or more or less dry there's a sensor inside where the lint filter is,try cleaning it up or try running it on timed dry to see if it runs any different,when on auto the heat comes on,when it reaches temp. the heat stops and the timer will advance,when it calls for heat the timer stops and the heat comes back on,it will do this until the clothes are dry.your model has an even heat board in it that can also cause problems but if the flame is liting it sounds like you have a block somewhere.go here this will tell you a little more about your model dryer. http://fixitnow.com/wp/2009/03/17/easy-fixes-for-two-common-problems-with-the-whirlpool-even-heat-dryers/
odess, sounds like you need a new set of coils for the valve. Easy job. Remove the bottom access panel and you will see the gas valve. Remove the top screws from the coils and the coils will lift off and then unplug the harnesses. Install the new coils. Part number for your coils is 12001349. Price about 18.00 Check them out at repairclinic.com This should take care of your heating issues. Catriver.
pop off the bottom panel,there's two clips that are on top of the bottom panel,stick a screw driver or putty knife in and pop the clips and pull out the panel to remove,start the dryer,if the flame ignites and then after a few minutes it doesn't ignite any more you have bad gas coils located on top of the gas valve,part number 279834 and they're around 25 dollars,if the flame ignites but goes out to soon most likely you have a blockage somewhere from lint buildup,pull off the vent line from the back of dryer and see if it runs any better,also unplug the dryer,remove the lint filter,remove the bottom panel and then remove the metal duct that the filter slides into and clean it out,vac and blow out all lint with a shop vac on the motor and inside the cabinet,if your vent line is a long run,remove it from the back of dryer and blow it out with a leaf blower,first check outside to make sure there isn't a cage or anything blocking the air flow before you blow out the line,if there is remove it and don't put it back.let me know how you make out and good luck.
If electric then the thermostat or the heating element has failed. If gas: First thing to check is the ignitor underneath the drum. (You have to open the panel to see it) It should glow shortly after the dryer starts, then the flame starts and the ignitor shuts off. If the ignitor does not glow then it or the thermostat is bad. If the ignitor is glowing but the gas does not light then the flame sensor may have to be replaced. If the gas ignites but does not stay on either the flame sensor or the coils are at fault.

I find that quite often the ignitor is out of alignment or the glass window is covered with lint. a gas dryer blows air through a
burner assembly to heat the air. The burner assembly consists
essentially of a gas valve, ignitor and a flame sensor. If any
part of the burner assembly malfunctions, the result will be low
or no heat and slow drying of the clothes.
There are two common styles of ignitors,
glow ignitors and spark ignitors. The ignitor ignites the gas
either by heating up and glowing, or by sparking. If the ignitor
fails, the dryer will not heat.
The easiest way to check the ignitor
is to observe it. Remove the small access panel in front, select
a high temperature setting and start the dryer. Watch the burner
assembly, shortly after starting the dryer the ignitor should
begin to glow or spark. If you see it glow or spark, then the
ignitor is working.
