A heat pump dryer recirculates the same air through a refrigeration circuit that pulls the water out of it. A HybridCare machine sits between the two. Whirlpool documents all three and gives the compact heat pump machine its own section with its own codes, because a fix that makes sense on one is meaningless on another. The first question on any dryer call here is which of the three is in the room. ### Why the vent is the story in South Florida Whirlpool publishes AF as Check Vent, and in this city that code earns its place. Damp air makes lint stick to the inside of a duct instead of leaving with it, so the run silts up from the outside in and the machine slowly loses the airflow it needs to dry anything. The symptoms arrive in order: longer cycles, then a hot laundry room, then a machine that shuts itself down on the high-limit thermostat, then a blown thermal fuse. Every one of those is a repair, and every one of them has the same root. We check the duct on any no-heat or long-cycle call before quoting a part, because replacing the part without clearing the duct is selling the same repair twice. OEM parts are ordered against the model number, and exact cost is confirmed after the on-site diagnostic.

On a vented machine this is airflow until proven otherwise, and Whirlpool agrees with that strongly enough to publish a code for it: AF, which its own pages label Check Vent. Pull the machine out and disconnect the duct at the back. If the clothes dry with the duct off, the restriction is in the run to the outside, not in the dryer. Then check the exterior flap, which seizes shut in this climate and packs solid behind it, and any flexible foil duct, which crushes behind the machine when it is pushed back into place. Only after airflow do you look at heat: the element, the gas valve coils, the thermal fuse and the cycling thermostat. ### It heats sometimes and not others, or it stopped heating entirely. A dryer that has stopped heating but still tumbles has power at one leg and not the other, or an open in the heat circuit. On an electric machine that is the heating element, the thermal fuse, the high-limit thermostat or a tripped half of a double breaker — and a breaker that looks on can still have failed on one side. On a gas machine it is the igniter, the flame sensor or the gas valve coils, in that order of likelihood. Important: the thermal fuse blows because the machine overheated, and it overheated because the vent was blocked. Replacing the fuse without clearing the vent buys you a few weeks. ### Mine has no vent at all. What changes? Everything downstream of the drum. The heat pump and HybridCare machines condense the moisture out of the air and either pump it to the drain or collect it in a drawer, so there is no duct to restrict and no exterior flap to seize. What replaces them is the condenser, which loads with lint and has to be cleaned on a schedule, and the drain path, which blocks. These machines also run cooler and longer by design — a two-hour cycle on a heat pump dryer is not a failure, it is how the technology works, and we say so rather than sell you a repair for it. ### How often does the vent actually need cleaning here? Once a year for a short straight run, and twice for a long one or one that climbs through a ceiling — which describes most condo installations in this city. Humidity makes lint pack rather than blow through, so a Miami duct loads faster than the same duct in a dry climate. Clean the lint screen every load, and wash it with soap once in a while, because dryer sheets leave a film on the mesh that you can feel but cannot see. --- **[Read full article: Dryers](https://whirlpoolmiami.support/appliances/dryer/)**
