This is usually caused by either a bad door switch, a loose door switch mount, or occasionally a problem on the control panel.
Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.
Door switch
or mount trouble can be caused by slamming the door or by opening the
door while it's cooking without hitting the Stop pad first.
There are
plastic mounts inside the microwave which hold the door switches and
onto which the door latches lock when you close the door.
The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.
Sometimes it's
a broken tab on the switch holder, allowing the switch to rotate just
out of position. This tab can be hard to see, since it is under the
bottom edge of the switch.
One test that sometimes helps is to
gently lift up (and/or push down) on the door or handle as you try to
start it. If it works or tries to work, then it's a door switch mount or
door alignment issue.

In all
likelihood the mangnetron is failed or failing, or perhaps even the Power Supply is
faulty. You need to have it serviced by a reputable service centre/man.
Ensure
you get a firm "Quote" before proceeding, and remember these days the
cost of repair can equal or exceed the price of a new one

Replacement of the
turntable motor should be carried out by a qualified appliance repair
service. YOUR
SAFETY IS PARAMOUNT! Attempt
this only if you are competent. But here is a basic method if you are
mechanically minded and have electrical safety knowledge. The motor assembly is fixed to the base
of the oven usually with two screws and access is obtained usually by
removing the inspection plate directly beneath the motor. It is
usually a plug in synchronous motor that revolves at a few revs per
minute but the plastic cogs in the motors gear box fail and the motor
assembly must be replaced. They are fairly inexpensive and obtainable
usually from a domestic appliance repair shop.
If you feel
confident, disconnect it from the mains power, remove anything in the
cavity and turn it upside down if it is a tabletop model, a little
more complicated if it is built in!
Remove the inspection plate,
sometimes it must be cut out with sharp cutters, and disconnect the
motor. Remove the motor and go and get a new one. Fit the new motor
and fit the inspection cover back on the base by turning it to fit
and using an extra screw fix it then put the microwave back in its
position. Plug it back in, with the turntable and plate. Put a cup of
water on the plate inside of the oven and heat for 20 seconds to
check the plate goes round.
Hope this helps.
