Tuntable keeps rotating when microwave door is open
My sunbeam (smw700) has stopped working. When I set the timer and tried to reheat, the timer would count down but the microwave light would not come on and the turntable would not rotate. When I opened the door the light would come on and the turntable would begin to rotate. Any idea what the problem might be?

Main control boardIf
your microwave runs for a few seconds and stops, the first thing to
check is the main control board to ensure that a shortage has not
occurred. If the part is defective then it will need to be replaced to
prevent continual shut offs. If this is not the issue, the next step
would be to check for a faulty touchpad.
the control board is not the issue and your microwave continues to shut
off after running for only a few seconds, the next thing to check is
your touchpad, which is also known as a control panel. Although uncommon
for this issue, symptoms are usually that the display and some buttons
are working properly; however, when selected some buttons are not
functioning. If this is the case the touchpad will need to be replaced.
What you are to do to solve the problem is to do a general troubleshooting on your oven below are instruction to follow.
The Microwave is a counter top model with a variety of preset
cooking options, including timed cooking at a variety of power levels and
sensor-cooking settings for popcorn, rice, beverages and single-serving
The sensor cooking and reheating features detect increasing
humidity levels inside the microwave and automatically adjust cooking
time for various types and amounts of food. This microwave
also includes a turntable and an electronic control panel.
Instructions below are step by step solution for your oven
to see if the microwave will start. If it will not start and the
display panel is blank, you may have a power problem. Unplug the
microwave and then plug it back in, making sure that all three prongs
of the power cord are fully inserted into the wall outlet. If this
doesn't work, check your home's fuse box. Reset the circuit breaker to
restore if necessary.
that the microwave door is fully closed. Press the Clear/Off button to
cancel any previous cooking instructions. Re-enter your cooking
program, including cooking time and food weight if necessary, and press
"Err" appears on the microwave display, press the Clear/Off button and
reenter your cooking program. The "Err" message will appear during the
sensor-controlled programs (Popcorn, Rice, Beverage or Reheat) if the
door is opened before steam is detected or if no steam was detected
within the maximum amount of time allowed by the microwave. Be sure to
leave the door closed during these programs, at least until time is
shown counting down on the display panel.
your control panel will not work or if an "L" is displayed on the
screen, press and hold the Clear/Off button for a full three seconds to
unlock the control panel.
your sensor reheat program is resulting in under- or overcooked food,
first try decreasing the amount of food in the microwave; the sensor
programs are designed for single servings of food. The sensor reheat
function works by measuring humidity inside the microwave--do not use a
tightly-covered dish with this setting because no moisture will be able
to escape and the food will overcook. Be sure that cooking containers
are dry; moist containers will increase the humidity in the microwave
and mislead the sensor, resulting in undercooked food.
your turntable is not rotating, first check to ensure that your food
container is positioned so that it can freely rotate without hitting
the microwave's interior walls; using a smaller food container can fix
this problem. If the turntable still will not rotate, lift the
turntable from its support and replace it carefully, ensuring that it
rests evenly on its support.
Check to make sure the plastic on the shelve holders or tuntable guide did not wear and expose metal. If these holders or brackets are wore and exposed metal it shorted out your micro wave. They need to be replaced and a fuse needs to be replaced inside the control panel,
Sounds like you have a bad door switch. Will have to take control panel off and test switches resistance to see if they are opening and closing properly. If a switch is stuck in or bad the microwave thinks the door is closed. This is where I would start. Let me know what you find.
