Strong warm air means the duct is clear and the problem is heat; weak or cool air means the duct is the job. Check the breaker as well — on an electric dryer, one of the two legs tripping leaves the drum turning and the heat gone. ### Why the duct comes first here Ducting in South Florida buildings runs further than the manual assumes — through a wall into a corridor, or up a riser shared with other apartments — and nobody cleans it. A dryer that cannot exhaust recycles moist air, the clothes stay damp, the cabinet gets hot, and eventually a safety device opens and the heat stops altogether. Fitting an element to that machine gives you a working dryer for a few weeks and then the same call. ### What an open cutout is telling you A thermal cutout is a one-time fuse that protects the machine from overheating. When we find one open, the useful question is not which part to fit but why it got that hot — and the answer is almost always airflow. Replacing the cutout alone is the classic false economy on this appliance: the new one opens too, because the reason is still in the duct. The vent is blocked Long runs, sharp bends and years of lint. The machine overheats, the safety devices trip, and the clothes stay damp. The heating element or the igniter An element that has failed open on an electric machine, or an igniter drawing too little to open the gas valve. Different parts, same complaint. Half the supply is missing An electric dryer on one of its two legs tumbles and does not heat. That is a breaker or a connection, not a dryer part. Feel the outside vent Strong and warm, or weak and cool. That is the fork in the road. Check both halves of the breaker It is free and it explains a share of these calls entirely. Look at the lint screen and the housing below it A screen that is clean and a housing full of lint is a common combination. It tumbles, and the clothes come out cold and damp What it usually means Airflow is the commoner answer here, and it is not a part An electric dryer running on one leg of its supply tumbles cold with a perfect element A thermal cutout that has opened is a symptom: it opened for a reason What to do in the next ten minutes Clean the lint screen, then go outside and put your hand at the vent while the machine runs.

Classic restricted airflow: the machine reaches its limit and shuts the heat off, then cools and starts again. The duct is where to look. ### The dryer is new and it does this. Then look at the installation. A new machine on an old duct, or one connected with foil concertina hose behind it, will do exactly this from day one. --- **[Read full article: Dryer not heating](https://frigidairemiami.support/symptoms/dryer-not-heating/)**
