The ceramic ignitor probably is broke. turnoff power and gas, then remove burner assembly ther are two screws holding it in. also loosen gas connecter .pull burner out an visibly check igniter you most likely will see the ceramic coil broken remove it and bring it and model # to a part house then reassemble burner

If the ignitor glows but does not light the burner you need to replace the gas valve coils. If there is no glow you must check all the thermostat safeties and thermal cutout fuses for continuity with a ohm meter. No continuity is a bad component. Remove at least one wire from each component before testing. Unplug the dryer before any test.
Modern gas dryers do not have a pilot light. They have an electronic ignitor (glow or spark). A glow ignitor turns on several seconds before the gas turns on and should get orange hot. A spark ignitor should make a clicking or buzzing noise.
Most likely the ignitor is bad but you can check it fairly easily to make certain. The best instructions I have found are at
If it is the ignitor it can be replaced with a few hand tools. Remove the bad ignitor. Write down the make, model, and serial # of your dryer. Call your local appliance parts store to see if they have one it stock before driving over there.
Thre is no pilot light. This dryer uses an ignitor (glow bar or coil).
Open the lower front "door" (small access door) and turn on dryer.
If the ignitor does not glow (bright orange), then the ignitor needs to be replaced ($60).
If it does glow, then the gas valve needs replacement ($60).
If it isd the valve, the internal spring is stuck. Do not try to repair it, you must replace it.
Check the thermal fuse on the blower housing. That is assuming the glow bar does not light up. If the ignitor is glowing and it will not light it is likely one or both coils on the valve are bad. (replace as a set) Eric
Should be a cover about the size of a quarter on the front lleft bottom...pop off with a small screwdriver and start dryer....look inside and see if the glow bar lights up...if glow bright orange, probably good, may need gas solenoids or ignitor
HI, Remove the front lower panel. Start the dryer and see if the ignitor glows. If it glows but the gas valve does not open, Change the coils on top of the gas valve. If the ignitor does not glow, test the ignitor for 120V. If there is voltage to the ignitor but no glow, change the ignitor. If there is no viltage to the ignitor, check continuity on the thermostats and the fuse that are located on the blower housing. Also test the sensor located on the burner. I hope this helps. Please let me know if I can assist you further.
Need more info. Does it rotate? If it has a viewing door on the front, you may see if the ignitor is glowing. If the ignitor glows, the ignitor (flame) sensor may be bad, and the ignitor will shut down.
