The light is on, but no one home...
The interior light will not turn off at all. The interior fan will only turn off if the door is open. The clock works, and all other functions except any cook functions. The turntable is not moving when door is closed and light and fan are on.
Turntable function set to on
Child lock set to Off
New wiring and breaker were installed for this. I did plug the microwave (using a heavy duty extension cord) to an existing plug on a different breaker. No change.

Re: Microwave was installed yesterday by "handyman"
Sounds like you have a defective door switch, door switch mount, or (worse) possible damage to the "hooks" which go into the holes in the chassis to activate the switches.
Be sure to unplug it first.
If this is an over the range model, you should not have to remove it from the wall to fix it.
Generally speaking, you remove the grille across the front, then you'll see a screw holding the control panel frame on. Once that's removed, you lift the control panel assembly up and out.
Then you can see the door switches and lathces, etc.
If you or a friend decide to work on it, we have *critical* safety and disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk

Light bulbIf your
microwave light bulb is not working, perhaps it has blown. The first
step is to replace the bulb and power on the microwave. If this does not
correct the issue, the next step is to check the socket and wiring to
verify if that is the problem.
Light bulb socket & main control boardIf
your microwave light bulb is not working after the installation of a
new bulb, check the light socket as well as the wiring to ensure they
are properly operating. If these sources are functioning properly, the
next step is to check for a faulty control board as a possible root
cause to your microwave light bulb malfunction.
Exhaust fan motorIf
your exhaust fan motor is not running, there are a couple of things that
you can check involving the motor to locate the problem. After removing
the fan motor, you can manually attempt to turn the fan blades with
your hand. If the fan motor is working properly, the blades should spin
effortlessly. If this does not occur and the blades are taught, the
motor will need to be replaced. Secondly, the fan motor itself can burn
out due to time and usage. Using an ohm meter, the exhaust fan motor
should read open for continuity. If it does not, then the fan motor has
expired and will need to be replaced.
that could cause the microwave exhaust fan to not work is a faulty
thermostat. A thermostat gauges the air temperature, which activates the
exhaust fan when required. If this part becomes flawed, the exhaust fan
will not energize and the thermostat will need to be replaced.
Main control boardIf
your exhaust fan is still not working and the microwave fan motor,
wiring, and thermostat are operating accurately, the root cause could be
with the main control board. Replace the main control board.
We had this happen to us tonight. We unplugged the microwave oven for 15 seconds and then plugged it in, but it the fan was still running. We then unplugged it for 30 minutes and the fan worked properly when we plugged it in again.
