The temp setting is not an "exact science" and is conditional:

The unit may be too close to a wall or other obstruction, such as an enclosure. It must be able to sense the temperature in the general area. When you move it, give it a few minutes the first time. After that, it will work correctly.

Hello LILSHAUNLSS5,
I am not sure I understand the description of the problem but let me take a shot at helping you. First off, you obviusly had a short of some sort that drew excessive current , causing a fault and ultimately got hot enough while drawing that excess current to melt something.. Here is where I am a bit confused. Power going to the heater elements comes off the thermostat and onto one side of your elements. If that is where the screw melted, can you remove th eoriginal screw and redrill and tap a new hole for a new screw to be used? If there is any question about the integrity of that termination then I wouldn't mess around with it since anything you do wrong , may result in a fire. So whatever you decide, be careful. If you can provide a picture or sketch of what it is that failed, I may be able to assist you further.
Good Luck,
Regards,
Rick

Probably the thermostat contacts have become worn and a certain amount of arcing is happening when they close. Replacement thermostat units used to be easy to change and were readily available for quality domestically manufactured oil filled radiators but these days it would probably be cheaper to buy an imported heater. You wouldn't lose by asking your local supplier and if they are still available check the internet price. It would be wise to check the wiring and internal connections before junking it.

check your fuses, may have blown the heat side. If fuses are good, and still no heat? replace the unit.

It is more cost effective to replace the unit.
