When I start script I have the door open(no real door) photocell led on for open, door open switch set to open (on).

In this case shouldn't you setup the switch 11 to PUD_UP?, e.g.
GPIO.setup(11, GPIO.IN, pull_up_down=GPIO.PUD_UP)

Pull up / Pull down resistors

If you do not have the input pin connected to anything, it will 'float'. In other words, the value that is read in is undefined because it is not connected to anything until you press a button or switch. It will probably change value a lot as a result of receiving mains interference.

To get round this, we use a pull up or a pull down resistor. In this way, the default value of the input can be set. It is possible to have pull up/down resistors in hardware and using software. In hardware, a 10K resistor between the input channel and 3.3V (pull-up) or 0V (pull-down) is commonly used. The RPi.GPIO module allows you to configure the Broadcom SOC to do this in software:

GPIO.setup(channel, GPIO.IN, pull_up_down=GPIO.PUD_UP)
# or
GPIO.setup(channel, GPIO.IN, pull_up_down=GPIO.PUD_DOWN)

(where channel is the channel number based on the numbering system you have specified - BOARD or BCM).

Maybe I'm not correct - not sure
