Most generally the problem will be a burnt out heating element, but the second most likely cause would be a bad thermal fuse. There are usually 2 of these fuses mounted near the heating elements, they are silver in color, and about the size of a quarter. All can be tested with a continuity tester. The heating units are aboy $15 -$20, and the fuses are about $5.00. Unplug the dryer before testing the units.

If the clothes have gems or anything that can come off then yes
Clothes may come out of the dryer smelling burnt due to overheating, prolonged drying time, or a buildup of lint in the dryer. This can cause the fabric to scorch and emit a burnt smell. It is important to clean the lint trap regularly and ensure the dryer is not overheating to prevent this issue.
When clothes come out of the dryer still warm, the fabric fibers are more susceptible to static electricity, which can cause them to cling together. This is due to the friction created as the clothes rub against each other in the dryer. Adding a dryer sheet or reducing the drying time can help reduce static cling.
Electrical energy is converted to heat in the heating element. It is also converted to magnetic energy in the motor, which is converted into mechanical energy (and turns the drum). If it is a gas dryer, chemical energy is turned to heat at the burner.
a heating coil. Like a blow dryer
The coefficient of drying is a number about the utility of a dryer. A simple example : You have dirty clothes dry, and you wash them. So now, you have a totally of 4kg wet clothes and you put them on the dryer. The coefficient of drying K come from this formula : K = Weight of wet clothes / Weight of dry clothes So it depends from the speed of your dryer!
Clothes rubbing against each other and the dryer drum create friction, causing electrons to transfer between the materials. This transfer of electrons builds up electric charge on the clothes. When the clothes are separated or come into contact with another material, this charge can be discharged as static electricity.
In the early 1800s, prototype clothes dryers were first starting to be invented in England and France. One common kind of early clothes dryer was the ventilator, made by a Frenchman named Pochon. It was a barrel-shaped metal drum with holes in it that was turned by hand over a fire. One early American patent for a clothes dryer was granted to George T. Sampson on June 7, 1892. Sampson's dryer used the heat from a stove to dry clothes and was another type of ventilator machine.
It's caused by static cling. As the clothes tumble around together, it causes friction between the fabrics, and certain fabrics (which is usually most fabrics) have the ability to create static electricity, or static cling, that keeps clothes stuck together. (Hint: try using Bounce sheets or other dryer sheets, because they prevent static cling on clothes).
Hard wired means that there is no plug and receptacle in the circuit powering the dryer. What you will find is a metal jacketed cable that will come out of the wall or floor and go right into the dryer.
There are a number of possible problems when a dryer is not getting hot. If it's an electric dryer the heating element may have burned in two. Or the relay that switches power to the heating element could have gone bad. If it's a gas dryer the igniter that lites the burner could have failed. The control that commands the heat to come on could have failed. These are other possibilities
