Microwave has power. set time to cook. hit start you here a click and timer counts down. it don't run and turntable dose not turn. Is this the new quiet mode.
No! The problem is one or two bad door switches, or possibily the keypad control board.
SOURCE: Microwave turns on, but no heat or turntable movement
The problem is that the magnatron is not getting power. Chance is that if could be a bolwn fuse inside the unit. If the fuse don't fix it then that leaves the charging diode, capacitor or the magnatron, or high voltage xformer of which without technical epertize I would not recomend attempting to replace. good luck

The door switches go bad...little micro-switches. Check them for switching on and off. Some are closed when the door is open, some are open when the door is open. It could even be that the catch has moved out of adjustment. If that isn't the problem, you have to consider the brain board which is usually so expensive that the microwave is not worth fixing.

This is usually caused by either a bad door switch, a loose door switch mount, or occasionally a problem on the control panel.
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.

is usually caused by either a bad door switch or a loose door switch
mount, which are pretty simple problems to fix.
Even though a door
switch clicks, it may still be bad inside.

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.

So the oven lamp comes on but the turntable and internal cooling fan do not?
If that is incorrect, please reply back and correct me.
If that's the scenario you have, then you have a bad primary interlock (bottom door switch) or its mount is broken or loose.
