Thank you waiting. here is the instructions that are very simple to follow.
the first thing you need to do is
Go to the front of the dryer, and insert a flathead screwdriver between the toe panel and the front panel. Push the screwdriver handle up to pry the top of the toe panel away from the dryer. Move the toe panel away from the work area.
Disconnect the wiring harness that connects to the flame sensor on the burner can. The harness will pull apart with your fingers. Remove the wiring harness from the burner connector on the base of the dryer below the burner.
Remove the two screws that secure the burner assembly bracket to the base of the dryer with a socket wrench. The burner assembly fits inside the burner tube, and the mounting bracket is in front of the burner tube.
Push the burner assembly forward to release the assembly from the bottom tabs. Pull the burner assembly out of the dryer. go ahead and
Disconnect the wire connector from the burner assembly to the igniter with your fingers. The igniter mounts to the front of the burner assembly. Remove the screw securing the igniter to the burner assembly with a Phillips-head screwdriver.
