I have a Kenmore gas HE2 dryer. I have owned it since new. age of dryer--6 yrs. My question is.. this dryer never seemed to get hot like some of the older dryers did. I checked the ductwork on interior and brushed and vac'd the best I could, and also ran hard pipe for vent, total of about 6' of pipe and 3 elbows. Is there an adjustment to be made that will increase the actual temp of air? Maybe this is just how these work. It runs a long time to dry a load of clothes. thanks, jeff
