In the past two weeks we have noticed that our dryer is taking forever to dry a load of clothes. Where normally we would be able to dry a load of towels in an 80 minute cycle, if not a little bit longer, it is taking us almost 3 of those cycles to dry a load. Or we only have to put in a few towels at a time it takes the 80 minute cycle. When I open the dryer I notice that there is indeed heat coming out, but also I have noticed maybe a little bit more humidity than normal. I don't know if its due to the clothes being in there not drying fast enough or if this is a result of the problem. Anyone have any ideas what I should check for?
