Everything on this page depends on the answer, and almost no article asks it. **Vented.** There is a hose or a pipe going out through a wall. The machine heats air, passes it through the drum, and throws the now-wet air outside. **Condenser.** No duct. The moisture is condensed inside the machine and collected in a container you empty, or sent to a drain. **Heat pump.** Also no duct, empties the same way, and runs noticeably cooler and longer than either — by design, not because anything is wrong. ::: ## Every load: the lint filter The one thing everybody does, and it is the right habit. Peel the lint off, and if the mesh has a waxy film on it — which builds up from dryer sheets — wash it in warm soapy water occasionally and let it dry fully before it goes back. ## Every few months: the housing under the filter The one thing almost nobody does. Lint gets past the filter and settles in the **slot the filter lives in**. Push a vacuum crevice tool down into it as far as it will go. Most people are startled by what comes out of a machine whose filter has been cleaned religiously for five years. ## On a vented machine: the whole run This is where a surprising share of slow-drying, long-cycle and no-heat calls actually end, and it is **not the appliance**. The duct is not just the flexible section behind the machine. It is the whole path to the outside wall — through a cabinet, along a ceiling, around two corners — and the flap at the far end that lint and birds both like. **The test that matters:** run the dryer and go outside. Put your hand at the vent. Strong, warm airflow means the run is clear. Weak airflow with a clean filter means it is not, regardless of when it was last done. A restricted dryer runs hotter than it was designed to and trips its own thermal cut-out — which is exactly why a blocked duct produces a **no-heat** complaint that looks like a failed element. Replacing the element on a machine with a blocked duct buys you a second failure and a second bill. It is also, straightforwardly, a fire subject. ## On a condenser or heat pump machine: the second filter Most owners of these do not know it exists. Behind the lint filter, usually behind a flap at the bottom of the door opening, there is a **finer filter or a heat exchanger** that catches what the first one misses. It packs slowly with fine lint, and the machine dries a little worse every month as it does — which is why the complaint is always "it has got slower" rather than "it broke". ::: Pull it out, rinse it if the manual allows, dry it fully, and put it back. On some machines the heat exchanger behind it also lifts out for rinsing; on others it is vacuumed in place. ## Once in a while: the sensor bars Two metal strips inside the drum read how wet the load is, and the machine ends the cycle when they say it is dry. Fabric softener leaves a film on them. A film means they read **dry too early**, and the cycle ends with damp clothes on a machine with nothing else wrong with it. A little detergent on a damp cloth, wiped along both bars. One minute, and it fixes one of the commonest complaints on any dryer. ## The heat pump footnote A heat pump dryer is **slower than a vented one on purpose** — that is the trade for drying at a low temperature, which is gentler on fabric and cheaper to run. ::: What is not normal is a machine that has become slower than it used to be. That is filters, then the heat exchanger, then the sensors — in that order, and two of the three are cleaning rather than a repair. ## The reason this page exists Fisher & Paykel no longer lists a washer or a dryer for the United States, while continuing to sell laundry spare parts and stacking kits. The machines are still here and still repairable, and replacing one with the same thing is not an option. That makes maintenance worth more on these two appliances than on anything else in the house. --- **[Read full article: Cleaning a Dryer and Its Duct: the Maintenance That Prevents the Expensive Repair](https://fisherpaykelmiami.support/blog/clean-a-dryer-and-its-duct/)**
