Microwaves My husband said that you are not suppose to open the microwave without pushing stop first!! (meaning don't just open the door while it is still cooking) I disagree and I think every American has opened the door before it stopped on it's own!! This has been a fun, but irratating conversation between the two of us!! Help!!

These above range microwaves "hoods" automatically turn on a cooling fan even when the microwave is not in use. If you read the manuals you will see warnings about the fans automatically starting. Even when the microwave is not in use opening the door likely interrupts the power to the automatic cooling fan.

My microwave will not heat up its in a defrost mode. How do I change it?

Sounds like one of the interlock switches(most microwaves have 3) is stuck or broken.The "hooks" on the door latch push these switches in when you close it.Take the cover off and you should be able to tell which one isn't working right.

You can tell if microwaves are being emitted if you get warm standing in front of it (seriously). But I wouldn't recommend that unless you want to cook yourself.

First thing that comes to mind is the door interlocks are out of adjustment or bad. Home microwave ovens are not supposed to operate like that. Some commercial models start the fan right away and run it after the cooking cycle is completed but I've never heard of a consumer model that does that.

Find your closest servicer here and have them take a look.

The fan may be on when the door is open but the oven is not generating microwaves at that time. Replace defective microswitch.

Do you mean that when you close the door, the fan comes on? If so, it sounds like a bad door switch. Probably the secondary interlock switch.
This failure is caused by opening the door when the unit is in cook mode. On ALL microwaves, not just one or two brands.......
Be sure to push the stop button before opening the door to add or stir... Or wait for the cook cycle to end. (This is why microwaves have a two step function on the stop/clear button. Hit stop once to stop cook mode and twice to reset timer).
You should use an ohm meter to check all 3 switches. The switch can be either stuck 'closed' or physically closed but not 'making' electrically.

the most common problem with microwaves is the door protection circuit blows a fuse. the door catches operate switch that if they do not operate correctly( normally after the door has been slammed). the good part is they place the fuse inside the casing. so remove the power open the casing( several screws) and check all the fuses in side.

The microwave has a safety door switches (2-3 micro switches)
The door mechanism should hit these micro switches. If you can open the machine, you can see that these micro switch has a holder that you can adjust and tighten to make sure that the hook of the door should activate them.

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 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.

If it jumps or moves just a little when you open the door, that is normal. It it actually runs, then you have a problem. Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP button) is the primary cause of door switch failure.
