I have a GE Profile Dryer Model #UPSR475EW1WW. Dryer came with the house when we bought it last month. It takes pretty much and hour and a half to dry a medium load of clothing (not towels or heavy stuff) The dryer gets warm but not hot. We cleaned a bucket of lint out of the innards of the dryer, with no noticeable results in drying time. We suspect an element is dead or malfunctioning. Help???
