Dryer ignites but does'nt light

Problem is an obstructed gas oriface. The burners light from the burner closest to the pilot assembly out like a dominoe effect. The explosion is because the gas has to make its way over to the pilot from a further burner thus filling the firebox full of gas before it ignites. This blockage is most commonly from a spider web inside the oriface itself. Pull the burner tray, remove the orifaces from the tray and look through each one cleaning them out with a toothpick from the backside. The orifaces should be threaded on the gas line coming off the gas valve (looks like a silver box inside the front panel)

This dryer has no pilot light. When you turn dryer on the igniter turns on and lights gas. If yours is not igniting, you could have a bad igniter or a bad heater cavity switch located behind back panel attached to dryer vent area, has two wires connected to it.

Replace the igniter. It’s not enough to lights up; it has to get to an appropriate temperature to ignite the gas.

you dont light it manually it has an igniter operated by electricity off the control board

Replace the flame sensor on the side of the heat canister. You may also have to replace the gas valve coils.

Most new dryers don't actually have pilot lights. They use an electric heater that turns red hot, and ignites the gas at the right time. If your trying to light the pilot light (which probably doesn't exist) because the gas isnt being ignited,,, its possible that the electric igniter needs to be replaced.

could be dirty heater you have to clean the runners and the smole nozzles that are in the manifold below the gas valve it's like a 9/16 size you pull them off and check make sure they are clear through, sometimes little spiderwebs build up inside them. if it's all clean, then it could be you flame rectifier/ aka: flame sensing rod, that tells the htr that there is fire so it keeps running. Let me know what happened.

That model does not have a pilot light.  It has an electronic ignitor.  If it is not igniting, either the igniter is not getting a signal to ignite, the igniter is burned out, or the gas solenoid is broken.  Probably the igniter is burned out.  It is item number 3018 at RepairClinic.com.
