Question about Microwave Ovens
The turntable works as does the light and display it just won't heat could it be as simple as replacing a high ampage fuse and if so were can I find it
No the problem is more than your fuze! Micro waves have a high voltage output transformer inside that goes bad. You can fix it yourself but if your not good with electronics I would have someone else do the job!

That doesn't sound good at all. Microwaves are death traps. It could have melted some metal inside. A fuse could have gone, but most likely the magnetron is shot. Might be safer to recycle and reinvest in a new microwave, especially for safety sake when dealing with controlling radiation.

Inspect the turntable base wheels and guides. If they are gummed up with food or other gunk, they will not turn and the turntable will not rotate. Clean as needed.
Remove the microwave case by unscrewing the casing screws with your screwdriver. Locate the turntable motor which will be directly beneath the oven floor.
Inspect the belt that connects the motor to the rotating table. If the belt is broken, replace it.
Touch the probes of a continuity tester to the electrical contacts on the motor. If the tester lights up, the motor windings are good, which means the motor is functional. If there is no light, the motor needs to be replaced.
Check the wires leading from the cord to the motor itself. Look for any breaks in the wire, or a wire that has been pulled off of any electrical connection. Any connection that has been compromised can be soldered back into place, but if the cord is damaged at all, it needs to be replaced.
Attempt to spin the motor by hand if the continuity is good and the belt is in place. It should spin freely, but if it is difficult or doesn't move at all, you will need to lubricate the bearing. Either apply spray or bearing lube to the motor axles to solve this problem, and allow the motor to spin freely once again.

you will have to replace the microwave, sounds like a burned out magnetron, replacing the magnetron is almost as expencive as a new oven...

Usually, power for the turntable motor and the magnetron tube (the microwave source) are controlled by a couple of things. One is a relay on the control circuit board, and the other is a switch that's operated by one of the door latches. It's possible the control board has gone bad or bad connections have developed. It's also possible the door switch has failed or is out of adjustment and the oven thinks the door isn't closed.
Diagnosing this kind of trouble may require working on the oven while it's operating. MICROWAVE OVENS USE HAZARDOUS VOLTAGES WHICH CAN KILL YOU. You might want to leave the repair to a professional because of safety concerns. Unless the circuit board requires replacement, it's probably worth having this repaired. Unlike some repairs, this one won't cost as much as a new oven.
