Hi - We have a dryer in the rental unit (Model # dsks433etOwb) and it takes awefully long time to dry. With a full dryer (barely 1 towel and mostly dress shirts and pants) it takes atleast 3 hours for a complete dry. We have checked the vents to make sure they are clean, we remove lint after every cycle and the internal parts of the dryer seem to generate enough heat.
Any ideas/suggestions?
If you have sufficient heat, the clothes tumble and the air flow is correct, your clothes will dry in regular time.
It seems like you have two out of three, so the third, the air flow must be your problem. You need to examine the blower/fan to make certain it is not broken, or clogged in any way. Plus to really check the vent system you need to partially disassemble the machine and really clean it out.
Good luck, hope this helps.
