Step by step procedure. http://www.repairclinic.com/vwo12 make sure your vent hose is not crimped/plugged, also clean out the vent housing at the end of hose, outside. House fires/plugged dryer vents. The dryer stays cool by having an UNrestricted air flow thru hose, otherwise parts heat up and fail. Clean the filter after every load or else you will develop the habit of not cleaning it.
