Laundry in an apartment with no exterior wall depends on dryers like the WTG86400UC, a discontinued 300 Series model with a drum of 4.0 cubic feet and a width of 23 1/2 inches. The price of going vent-free is heat: a condensation dryer releases its waste heat into the room it stands in.
In a small, shut laundry closet that heat makes a measurable difference. It keeps recirculating warm air, so drying slows, and propping the closet door open for a cycle really does help. It has touch control and a condensate reservoir, and needs no outside duct.
Inside the drum, moisture sensor bars read how damp the clothes are. A film of fabric softener on them blinds the sensor, so loads finish damp even though the cycle says dry. A little vinegar on a cloth often brings back normal results, which is where we begin.
Heat that the dryer cannot send outdoors ends up in the room. Shut in a closet, the air warms and condensing becomes less efficient, so cycles drag. Propping the door open helps.
The bars inside the drum that sense moisture. A film left by fabric softener stops them reading properly. A little vinegar on a cloth often fixes it.
Somewhat, yes, for a vent-free dryer in a small space. It is not a malfunction. If the room becomes uncomfortably hot, better ventilation of the space is the fix, not a repair.
