Hello. Ok to answer your question, the ignitor and burner assembly is located at the bottom of the dryer under the drum. To gain access, remove the lint filter and remove the 2 screws under the filter first. I would use a plastic putty knife, there are two tabs on the left and right front in between the top panel and front panel. Take the putty knife press in on the clips and it should release the top. Then there should be two screws 1 on the left and 1 on the right. Remove those screws, then unplug the door switch. Pull panel forward and lift up. This will gain you access to the burner AP3607674 and ignitor AP3094138.

To access the thermal fuse, you will need to remove the back panel of the dryer. The thermal fuse AP3176214 is located on the side of the heater housing. To test the thermal fuse, you will use multi-meter. If its good it should read closed for continuity. Good Luck!
