SOURCE: Microwave works with the door open

The top door switch is almost certainly defective or loose. Most likely the latter, and possibly due to a loose or broken mount. Chances are that only the fan and light are on, but it's not wise to take chances with microwave energy, whuch can cause burns and fire. One way to possibly test this theory is to pull up gently on the door and see if it stops doing it. But that's not a foolproof test. A broken or loose mount can be caused by inadequate plastic or improper assembly techniques during manufacturing, by slamming the door, or other physical damage. Bad door switches are usually caused by opening the door while it's cooking instead of hitting the STOP KEY first. I have a helpful text file on door switches with safety tips that will help you. You can find it by searching on Yahoo.com (not Google) for microwave safety.txt Good luck and be safe!

SOURCE: Microwave runs when door open

This is probably a a bad door switch or door switch mount. Chances are only the fan and light are running when you open it, but better safe than sorry. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure but not the only one. I have a text file called "doorsw.txt" which helps in diagnosing and repairing door switch problems, and a file called "safety.txt" which is of vital importance. You can find these files by searching at Yahoo.com (not Google) for this: microwave display safety.txt If you still have a problem, please write back with more detail. Be safe!

SOURCE: Microwave does not turn off

This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

SOURCE: when I open my microwave door, it starts running

.
In most cases, it's not actually cooking, but instead the fan, turtable and light may be on. Yet it does need attention.

What this usually means is that you have a shorted door switch or a bad door switch mount.

It's easy to tell if it's actually cooking, just place a cup of water inside and see if it heats.

If so, that could mean a stuck relay on the control board. If so, we repair these for customers nationwide with our guaranteed $39.95 service. Far less than a new board.

I would recommend changing the diodes as well. This will usually take care of the problem.

Makes random beeping noises all hours of the day & night. Annoying but wondering if something is wrong or if there is something we can do to stop it? Works fine otherwise!


I have never heard of that happening before. I think you need to ask Kitchenaid direct. Once the machine is off and dead, it should stay quiet until you press a button or open the door.

Kitchenaid microwave model KCMS1555RSS-2 door stuck, does not open


Hi Chan Sing,
If your microwave oven is brand new and under warranty then please take it to the place where you bought it from to claim for warranty.
If it over warranty then try this;
First off the power and unplug the microwave oven, open the screws off the cover and slightly lift and pull out the cover from the microwave oven. If you are not a technician then be care full what you are doing.
After you have removed the cover then you will see that at the place you posh the door eject button, behind it there is the mechanism that opens the door when you push the button from outside.
Now you have to analyse the simple mechanism if you are a non technical person, in here you will have to lift a small plastic up which we can call the lever. this is made up of plastic and it should be white in colour.
If you have any problem please let me know.



Regards
Ashwin

Microwave will not run a cook cycle. Touchpad functions until door is opened or start button is pressed. When door is opened display goes dark. When door shuts display lights all characters and then says...


BEFORE DOING ANYTHING DISCONNECT OVEN FROM POWER. I do NOT recommend doing repair by yourself, if you NOT are really very familiar with electric repair, or have at least basic training in electric device repair and maintenance.
"When door is opened display goes dark. When door shuts display lights all characters and then says "touch clock"."
Obviously, by opening door, oven gets disconnected form power line.
This is mostly caused by loose connections on wiring socket, and can be anywhere inside. Check security micro switch on door latch. This switch normally disables only running the oven when door is open, for security reasons. In your case, it seems that opening door disconnects oven from input power. Sometimes the switch is loose, or wires are not firmly pushed in the socket. If the power line wiring is loose, and by opening door looses contact with socket, it can touch metal housing inside, cause short, electric shock, serious even mortal injury and fire. This is dangerous high voltage switch, and to access it one must open oven from the back and take off the cover. I do not recommend doing it by your self.
Rem: Replacement micro switch is couple dollars.

Why is the microwave running without being turned on?


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.

Inconsistent power


If it's totally dead, the main fuse may have blown. However, since it was inconsistent before it went dead, it might lead me to think that you have a loose connection. Sometimes they heat, lose continuity, and then work again when they cool. A defective thermal protector might also cause this.

My GE XL1400 over-the-range Microwave does not power on to cook. The inside light will not turn off when the door is open or closed. Unplugged and re-powered with no change....where to start?


Easy....the reason the light does not go out when the door is closed and the microwave gun is not activating...is due to your door switch not "sensing" it being closed. Sometimes there two electrical switches on the door...yours probably have one and the actuating arm...metal tab on the switch is probably bent and need to be re-bent to sense door closure. Take apart the microwave and re-bent this switch tab...it's relatively easy to find and correct. The door switch might be bad too...won't cost much. 9 times out of 10 it's a bent switch bar.

Model KCMS1555R KitchenAid Microwave Oven turntable continues to operate even when the door is open. It seems to work otherwise. I disconnected it from the power hopping it would reset but that did not...


This is an extremely dangerous situation, if the microwave oven is running with the door open it means the safety interlock switches are not working the way they were designed to, and needs to be checked out for safety reasons. I recommend unplugging the device and not use it until it has been checked by a qualified technician.

Microwave has no power the powe sourse works


Hi, your microwave can be dead for many reasons.

It may be the fuse, which is usually located on the floor of the oven behind the control panel or between the door switches.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO)/ thermal fuse on or near the magnetron or on top of the cavity / bodyof the oven.

If it goes dead for a while during or after cookingthen comes back on, the magnetron is probably overheating and causingthe magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should readopen, as opposed to the others, which should read closed.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

Ifit goes dead or blows the breaker (or GFI) when you plug it in or open or closethe door, then there's a problem with a door switch or door switchmount.

If it's intermittent or random, it may be a badconnection, usually on the control board or a loose fuse holder, oreven an intermittent fuse.

You should do a continuity test onthe fuse while it's in the holder (with the microwave unplugged, ofcourse) then turn the fuse by hand or take it out and put it back in,then test it again.

If you remove the fuse, then press the meterleads against the ends, it can allow internal contact to be made andmake a bad fuse appear to be good.
