Go to this link....you can download the users manual. The procedures for setting the clock are on page 22 of 68. JVM1950SR1SS GE MICROWAVE Manual

If I'm going to reply at all, I have to warn you not to go near the insides of a microwave unless you understand how to discharge the HV capacitor. It can hold lethal voltage even when the oven is unplugged. Do not depend on a self-discharge resistor, it may be faulty or not there. I can't find a photo of that particular model, but here is one of a typical layout. http://www.appliance-repair-it.com/images/microwavelayout.jpg The HV capacitor is typically a metal can about 5" long, like this http://thumbs4.ebaystatic.com/d/l225/m/m95TA3ZdkVPdKC7vYn0zvog.jpg It may also be cylindrical.

It can be related to short in the main capacitor , short in the transformer or the surge capacitor. Also it can be due to short in the Magnetron or even the fault in the board.You can isolate the short by disconnecting these one by one till the circuit holds which will confirm the case.

This is usually caused from a bad magnetron. The door interlock switches couls be bad or the high voltage diode could be bad.

There could be a bad interlock switch. I have seen this blow the fuse. The high voltage capacitor could be shorted. This will blow the fuse immediately. Take care around the high voltage circuit. Make sure you short the capactor terminals to groound before touching any connectors.

in control panel replace buzzer

Some oven u have to open the cover wrapping ur oven.

Check the door switches.

It will get hot in a very short period of time. Could you have set the time for a few seconds instead of a few minutes? Thermal issues normally take the unit out until replaced. They are one shot thermal protect devices.

No battery. You will need the control board.

Wrong part or the fan blades installed backwards

For that sound it will need atechnician but for not heating you cqn replace fuses

That is a hard one without looking inside the workings to isolate the loss of power.
