I bought this a month ago.  run time for a program is especially long.  i just had the repair guys here and they are ordering a new sensor which will not be here for a week. Between every dry there is a lot of dust on top of the dryer and very little in the lint trap even for towels.  the repair person told me maybe it wasn't connected good or there was a hole in the line. Since I bought all connecting parts new and have had it reconnected (after having ductwork throughly cleaned) I know this is not the problem. this has been going on since the first day I received it..  I'm hoping a new sensor will fix the drying time but still have the dust problem.  so far not worth the price i paid but will revise review if the situation improves.
