Will burnt smell eventually go away?

Yes, a temporary burnt or smoky smell caused by minor dust burning off a brand-new heating element during its very first cycle or a minor lint particle scorching will eventually dissipate on its own after running a few normal loads. However, if the burning smell is caused by an active structural problem—such as thick lint caked directly against hot heating coils, a failing motor with shorted windings, or a severely restricted exhaust vent trapping extreme heat—the smell will never go away on its own and will worsen until a fire occurs or a fuse blows. You can troubleshoot burning odors easily by checking exhaust airflow. You can verify that your corrective action is successful when thoroughly cleaning out all trapped lint and repairing faulty components eliminates the burning smell permanently.
