Wet packs are appearing intermittently across several loads. Which of the following is the least likely cause?

解析

Dynamic-air-removal cycles generally dry better than gravity cycles because the post-cycle vacuum helps pull moisture out, so cycle type is not a likely cause of wet packs. Overloading, dense packing, short drying times, premature door opening, clogged drains, faulty steam traps, and wet incoming steam are all recognized contributors. Cooling loads on a cold metal surface or in a drafty area also produces condensation.
