Likely when you cleaned it, grease mixed with the cleaner you used got between the button panel and the actual button switch behind the panel, making it stick on. Will need the model to determine how to remove the panel to clean underneath...OR, it may dry out and start working normally again.
SOURCE: FAN!!!
Oh, it turns out the the microwave was over heated and the fan was cooling it. The fan will automatically turn on and stay on until your microwave reaches normal temp. just unplug your microwave and let it cool off. then plug it in and everything should be just fine.

This
is usually caused by either a bad door switch, a loose door switch
mount (which are pretty simple problems to fix) or
occasionally a
problem on the control panel.
Even though a door
switch clicks, it may still be bad inside.
Door switch
or mount trouble is usually 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.
If you or someone you
know decide to look
into it, we have critical information on safety, disassembly and door
switches at our site, and our link is at our listing here on
FixYa:.
You can find helpful
exploded view diagrams and order parts by entering your full model
number here.
There should also be a "mini-manual" hidden inside the unit behind the control
panel or hidden on the left side behind the grille, which is very
helpful when troubleshooting & testing.
If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.
If you only need a
switch, you can order a universal type here for $5 postpaid.
If you think the problem
is on the control panel, we repair these nationwide by mail
for $39.95 postpaid in most cases in about a week or so.
We're
happy to help you with free advice and we'd appreciate your thoughtful

SOURCE: Microwave doesn't heat anything
Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.
The cost of the magnetron is about 95% of the cost of a microwave oven.
Most people don't, for this reason, replace the magnetron, they replace
the whole oven which is probably what you will end up doing.
There is a possibility that the circuit that provides power to the
magnetron is faulty and you need to take it apart, find the proper
electrical leads and test them with a volt meter. To do this you have
to remove it from its mounting and take it apart. It is a fairly
lengthy process however.

We have a similar problem! It sounds like a problem with the microswitch inside the unit that the door is suppose to engage when closed. If not engaged properly, it will not cook. We had the switch replaced last March but it has started acting up again. We can press in on the door and/or lift it slightly and it will cook. Try putting time on the counter and hit start. It the word "cook" appears then try moving the door slightly and see if the turntable starts turning. If not, then you may have a more serious problem. Good luck!
Unplug the oven and unfasten the cabinet body, using a screwdriver. The body should be attached along the back as well as along the sides or bottom.
Slide the cabinet body back slightly to clear any internal brackets, then lift it off.
Clean the oven, using a vacuum with plastic crevice attachment. Vacuum the fan and other internal parts, then vacuum the vents underneath the oven, on the back and inside the chamber.
Reassemble the oven and plug it in.
Fill a small bowl with a 50-50 mixture of water and white vinegar, then set it in the oven and turn the oven on high for 5 minutes. When the mixture boils, it will remove stubborn smells inside the vents and loosen food particles on the oven walls.
Wipe down the oven walls with a clean sponge.
