Take away the airflow and everything else follows: the cycle runs long, the cabinet gets hot, the thermal fuse does its job, and the machine looks broken. That is why this page treats the two together — on the great majority of these calls, the part that failed was doing exactly what it was supposed to do. ### What actually goes wrong - **The vent**, which is not the appliance and is behind most drying-time complaints. - **The heating element**, or on gas machines the igniter and valve coils. - **The thermal fuse**, which is a symptom of the duct rather than a cause. - **Cycling and high-limit thermostats.** - **The moisture sensor bars** in the drum, which end cycles early when coated with softener residue. ### These machines are no longer built, and that is fine KitchenAid stopped selling dryers in the United States in the second half of the 2000s. The vented electric and gas machines still working here are simple appliances, which is why so many of these calls end well — elements, thermostats, thermal fuses, belts, rollers and idlers are commonly still available because the platforms were shared with other badges from the same corporate group. ### What it costs From $165. The exact cost is confirmed after the on-site diagnostic. What this involves Double breaker checked before any part is discussed Element, thermal fuse and thermostats tested as a circuit A blown thermal fuse treated as a symptom of the duct The breaker first, on an electric machine These run on a double breaker and half of it can trip on its own, which leaves the drum turning and the heat gone. That single check has saved a lot of people a service call and it costs nothing. Measure the airflow Before condemning any part. A machine that cannot exhaust cannot dry, and everything downstream of that — long cycles, a hot cabinet, a thermal fuse that keeps going — is the duct talking. Test the heating circuit as a circuit Element or gas valve coils and igniter, thermal fuse, cycling thermostat and high limit. They fail in a chain and replacing one without reading the others brings the appointment straight back. Deal with the cause, not only the part A thermal fuse that has blown is almost always telling you about a restricted vent. Fitting a new fuse and leaving the duct is how the same machine blows another one in a month. Heat and airflow are one problem A vented dryer works by heating air and throwing it outside.

What it costs From $165. The exact cost is confirmed after the on-site diagnostic. ### It runs but there is no heat. On an electric dryer, check the breaker first — these run on a double breaker and half of it can trip, which leaves the drum turning and the heat gone. If the breaker is sound, it is the element, a thermal fuse or a thermostat. On a gas machine it is the igniter or the valve coils. ### It takes three cycles to dry one load. That is the vent until proved otherwise. Lint fills the duct behind the machine, the run through the wall and the flap outside — and here the air going in is already humid, so a partly blocked duct that would be survivable elsewhere is not. Clean the whole run rather than only the lint screen. ### Is a blocked vent actually dangerous? Yes, and it is the one thing on this page worth treating urgently. A restricted duct traps heat in the machine and lint is the fuel. A dryer that is hot to the touch on the outside, that smells scorched, or that keeps blowing its thermal fuse is telling you about the duct rather than about itself. ### What does the repair cost? From $165, with a thermal fuse or a thermostat at the low end and a heating element or gas valve coils above it. The exact cost is confirmed after the on-site diagnostic and agreed with you before anything is ordered. --- **[Read full article: Dryer heating & airflow repair](https://kitchenaidmiami.support/services/dryer-heating-and-airflow-repair/)**
