power relay seems stuck,try to replace it or replace the main control board

Yes, unless a technician may have removed it during a previous service. It should be located behind the controller assembly, sometimes in a small envelope.

At my Web site, I have a video showing you how to remove a typical microwave controller in about 5 minutes.

Most microwaves should be similar to this https://producthelp.kitchenaid.com/Cooking/Microwaves/Microwave_Product_Information/Setting_the_Clock_for_the_Microwave

Yes, it is probably a bad relay. Usually appliance techs just replace the whole control board, because those relays can be hard to find and buy.

you cant fix the fan you got to take it to someone who knows about things like that?

Yes, it is most likely a bad relay on the control board.

Hi Jill, what the screen indicates is that the door is not closed There are a number of internal contacts that have to be closed for the microwave to work If any of them are wrong, they can give you that information. Depending on the brand there may be between 2 or 3 contacts in the door area that generate that warning Indicate brand, model and type of equipment you are commenting on, in order to find the best possible solution I wait your answer Regards Franco Dosil Hola Jill, lo que te indica la pantalla es que la puerta no esta cerrada Hay una serie de contactos internos que tienen que estar cerrados para que el microondas funcione Si alguno de ellos esta mal puede darte esa informacion Derpendiendo de la marca pueda haber entre 2 o 3 contactos en la zona de la puerta que generan ese aviso Indica marca, modelo y tipo de equipo del que estas comentando, para poder encontrar la mejor soluci?n posible Espero tu respuesta Saludos Franco Dosil

Adjust the door switch mounting strip as adjustment is provided if not o.k check door switch connector on the PCB assembly for loose contact or soldering.

To fix this issue you really need to hire a professional for safety purposes. You are looking around $500 + or - $50 for this repair.

Here's a diagram of the door. On the inside of the door is the frame, #2. This can be removed very carefully with a small flat bladed screwdriver and work slowly around. The frame is held in place with plastic tabs on frame. Once frame is removed, you should see the two screws that hold the handle in place. Good Luck!

I'm sorry to say that it's most likely the magnetron that's shorted out (the high voltage device that produces microwaves). It's usually the case with ovens this old that a compatible replacement won't be available. There's also the fact that your oven is likely way past it's 'end-of-life' date so even if you could find a replacement, other components will begin to fail as more time passes. In short, save yourself the money, time, and frustration with a new unit. Good luck!

Hello, Cher -The microwave touch pad may need to be replaced.Since you have experienced the problem for "some years," have you contacted a business in your area which is authorized to repair KitchenAid microwave ovens? If not, I suggest you do so, if you wish to have the problem properly diagnosed and fixed.Best wishes.

You must presume Tech knows what he is talking about , but get 2nd opinion, then you will be sure.

For the KitchenAid microwave, model: KHMS2050SSS2 I found that i did not have to remove the screw. what i did was loosen the screw as much as it would go before getting tight again.(hard to screw) then on the bottom end of the door hinge (lying on its side) i pryed the bottom hinge off its mount. (with flat head screwdriver) from there i was able to get at the screws to separate the black surrounding stuff from the outside door... then finally i could get inside to get at the door panel controls. I noticed a whole bunch of condensation and on the back of the touch panel (electrical board).. i will replace that part as I think that is the culprit as to why the keys get pressed randomly, beeping randomly and wonkiness :)

It sounds like the door spring had broken. Take the covers off and it should be apparent what had happened. It may be a part you can get at the hardware store or it may be an OEM part.

try to turn the coupling, either stripped broken coupling, or bad gear in drive motor. should not be able to turn by hand

have it inspectied my a real company . if it was wired wrong, such as the oven was 220 volts and the microwave was 110 volt they tried to split the 220 down to 110 and wired it wrong. my question is was there a oven there before, if not did they run new wires for that oven . 220 volt needs 4 wires to run it , to be right. It sounds like 220 was put to the microwave.

If the magnetron is still operating when off, needless to say , its pretty dangerous. The door lock unit usually has at least 3 microswitches to ensure that the door is closed and ready to operate. 1 of the switches is a safety switch which will cause a dead short if the door is forced open or something goes wrong with the door not closing correctly. This will "blow" the internal fuse in the machine. If the magnetron keeps going, its possible one of these switches have failed or there is an electronic fault causing power to the magnetron in the off position although, I would strongly feel this would be unlikely. These machines are made with a lot of safety devices.

Checking and replacing the three microswitches would help.
