A dryer that needs two cycles is rarely a broken dryer. Nine times in ten the machine is fine and the air has nowhere to go. In a house that is your problem to solve. In an apartment building with a stacked riser, it very often is not, and knowing which you are in saves you a service call.
How a dryer actually works
It heats air, passes it through the drum, and carries the moisture out. Everything depends on the last part. Restrict the exhaust and the moist air stays in the drum, the clothes stop drying, the cycle runs longer, the element runs longer, and the cabinet gets hotter than the design allows. Eventually a thermal fuse opens to protect the machine and you get a drum that turns with no heat at all.
People then replace the fuse. It lasts until the next long cycle, because nothing has changed.
The stack is the difference
In a lot of the pre-war and mid-century buildings around here, individual apartments feed into one shared vertical duct with a fan at the top. Three things follow from that. Your lint is not the only lint in the duct. A booster fan problem upstairs presents in your apartment as a slow dryer. And you cannot clean any of it, because it is common property.
The tell is that the machine tests fine. Element good, thermostats good, airflow at the machine outlet good, and drying time still terrible. At that point what you need is the managing agent, not a technician.
What is yours to fix
- The lint screen, every load, and a wash under a hot tap monthly if you use dryer sheets, which leave a film that blocks airflow you cannot see.
- The four feet of duct between the machine and the wall. Rigid or semi-rigid metal, not vinyl, and no more bends than the layout forces.
- The gap behind the machine. Pushing a dryer all the way back crushes the duct into the shape of the problem you are trying to fix.
If all three are right and it still needs two cycles, get the reading taken before you buy anything. Call 914-527-5055.
