my advice if you have little knowledge about electronic, please take it a qualified technician. Still you want to repaire it by yourself then you need to very slowly do not damage any cables or connectors in the unit. Ashwin

This fault is cheap repaire if you try Check relay on the control board, mostly the contacts on the relay are carbonised and get attached together so when the oven shakes like you open the door the contact is present in the relay and the microwave starts.

There few things which can stop heating -your magnetron can be heating up very fast - your themostat mounted on the magnetron must have failed - the electronic board can also stop heating process Ashwin
Open the back cover and you will surely be able to identify the bulb location. Make sure your power is pluged out before you attempt any repaires. If you cant locate the bulb send me picture of the opened oven Ashwin
