It gets very hot and can't contain that much heat without melting.
Above is true but what happens is the item (load) protected by the fuse is pulling more current or number of electrons through the circuit than what it was designed to handle. The more friction from electrons fighting each other, to get through the wire (fuse), the more heat is produced, the material that the fuse is made of, can only handle so much heat and then it burns open. This can happen by a number of things that may change.
The actual load can change or the voltage pushing the electrons through the wire may have gotten higher. It's not a simple answer to say why the fuse actually burns open.

Fuse to ECU melted in fuse panel of 99 Tahoe replaced fuse and car runs fine what would cause the fuse to melt what would you adivse to do next?
A FUSE IS A SUBSTANCE OR METAL THAT CONTROLS ELECTRICITY A FUSE IS A SUBSTANCE OR METAL THAT CONTROLS ELECTRICITY A FUSE IS A SUBSTANCE OR METAL THAT CONTROLS ELECTRICITY
Is it a safety hazard to replace a 3 amp fuse with a 5 amp fuse?
Yes. You put a bigger fuse and you will melt the wire and cause a fire hazard.
What will happen if there is a gap in electric circuit?
If the gap is small then you may get 'arcing'. This is where the electricity will jump from one point to another (cable end to cable end). This could cause a fire. If the gap is too large for the electricity to jump then in effect there will be no-circuit.
What is fusing current?
The fusing current is a value of current that causes the fuse to melt and interrupt the flow of current. Usually, reference is made to the minimum fusing current which is the smallest value of current that will cause the fuse to melt.
What is the use of fuse?
A fuse is a weak point in an electrical circuit designed to fail if too much electricity passes through the circuit. If there was no fuse and too much electricity went through it it could cause fires or damage the equipment.
If a over sized fuse is used instead of the correct fuse what could happen?
if you use the a fuse that is larger than the amount of current that the wire can safely carry you could cause the wires to get hot (even possible melt) and cause a fire You could burn your house down.
What is uses of fuses?
A fuse is a weak point in an electrical circuit designed to fail if too much electricity passes through the circuit. If there was no fuse and too much electricity went through it it could cause fires or damage the equipment.
Define fusing current?
The fusing current of a wire is the current that will cause the wire to overheat and melt, which will break the circuit, acting like a fuse.
What can cause no electricity to the dash on a car?
more than likely a blown fuse if not that a loose or cut wire most likely
What would be the cause and solution of partial electricity going out if wires may have touched when fixing a closet switch?
Blown fuse or tripped breaker. Replace the fuse or reset the breaker.
What safety devices provides a weak link in a circuit that will melt if it received too much current thus breaking the circuit and stopping the flow of electricity?
The device that has a melting link in it is called a fuse.
Will a component in my car work if I remove it's fuse?
Not if that component requires electricity, which it probably does or it wouldn't have a fuse. If you remove a fuse, no electricity can flow through the circuit.
