When you open the door to the dryer there are 4 screws you need to remove (2 on each side) in order to remove the front panel. Once I removed the front panel I then turned the dryer on to see what was happening inside. The heating element was turning orange with a glow but the gas wasn't igniting. After looking on-line I figured my next option would be to replace both gas valve coils (one is 2 terminal & the other is 3 terminal). Once you have the new parts & are ready to install them unplug the dryer. All you need to do is first, unplug the 2 plastic sockets that feed the electricity to the coils (they have wires attached to them) unscrew the bracket that holds the 2 coils in place, pull the old coils out & put the new coils in, replug the electric plugs, re-attach the bracket that holds the coils into place, plug in the dryer & turn it on. Test it without the panel on so that you can see that the gas ignites. My husband was very happy when I told him I repaired the dryer - beats paying another repair man.
