I keep getting "DOOR" message on display. I've changed the 20 amp fuse, but cannot locate the 15amp fuse. Need to see how to get into the microwave to try and test the switches.

SOURCE: KitchenAid Superba Microwave/Oven, Microway Door message

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. Its continuity must be checked.

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.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

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 may 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 only need a switch, you can order one from us 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.

Remove the front panel by removing the screws located on the inside of the door (note hold door inplace, since it is heavy and will fall out after screws removed). Unscrew screws located on bottom of plastic retainer (2 each) Remove tension spring. Note 2 are included right and left.

If the switch mount is broken, it's usually more economical and safer to add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

HI, this is an indication of a failed door switch. When the switch fails, the control cannot recognize the closed door signal. Simply replacing the door latch mechanism will solve this issue.

Replace the door latch assembly, asap.

Hi, it is caused by a blown 20 amp fuse in series with the Primary door switch.

CORRECTION: Most often the first attempt is to change, or adjust, the primary door switch, but components (20 amp fuse, 15 amp fuse and cavity thermostat) in series with the primary door switch are the culprit. Check and replace as necessary the 20 amp fuse, the 15 amp fuse or the cavity thermostat.

Has no display


Arnie, if the inside light does not come on when you open the door, you most likely have a blown fuse. Un-plug your microwave and if you take the cover off and look to see where the power cord comes into the back of the unit. You will need to look for where the black wire from the power cord attaches to a small circuit board. Right where it attaches will be where you usually find the fuse for the unit. Normally most microwaves run on an 15 amp fuse but some use a 20 amp instead. It will be etched into one end of the fuse what size you are going to need. You also need to make sure that you get a ceramic fuse when you get it. Most appliance repair shops will probably carry the fuse or be able to point you in the right direction for getting one.

Microwave door warning light


If this is a built-in wall oven with microwave on top, it is probably the 20-amp fuse located above the microwave. It is wired in series with 1 of the door switches, hence the "door" message. The only problem is that you have to pull out the microwave oven (at least part-way) to be able to get to that fuse.

My whirlpool microwave/oven combo is displaying a "DOOR" error message, and the microwave won't work. I have replaced a 20a bus fuse and all 3 door micro switches... It is still displaying the "DOOR"


When microwaves first got popular I used to be a helper with my next door neighbor who fixed them. I does sound like you should have covered it with those switches. If you close the door very slowly, pulling back on the door see if you can hear all 3 switches clicking. You should be able to hear them easily. If you only hear the first 2 try pushing on the door to hear the 3rd. If it will click with pressure on the corners or in the middle then you door is tweaked, possibly from pulling on the door hard to open it or smacking into something on the edge. If you can hear all 3 switches and it still wont start then its going to be the sensor that receives the signal from the switches. I'm not sure how accessible those are on today's models since they make them as disposables now, back then they cost around $500 so they were serviced.

Microwave stopped working


Hello there and welcome to fixya
This is a fairly common issue with microwaves
Normally the issue that you are dealing with is that the dor switch has went bad or the electrical wiring may be getting loose so what i would do is first remove the outer shell of the microwavethen get to the door switch and find the wires that are going from it to the connection poing then make a note of where the wires are connected at then remove the wires and test using ohm meter set at the lowest setting you should be getting a ol reading when the door is open then shut the door and you should show a little bit of continuity when the door is shut something like 020 or something like that however if it does not move or the numbers are really high then it should be replaced ok
I have posted a link here for you to follow on how to test it and several other parts ok http://www.ApplianceRepairLesson.com

Khhc2090s trouble


The sensor errors are probably just from opening the door and interrupting the sensor cook cycle.

By the way, you should always press "Stop" before opening the door of a running microwave. Otherwise, the door switches will prematurely fail.

I would first check the door switches and their mounts. See this help file.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

It's possible the high-voltage capacitor is bad, but I suspect a bad interlock monitor switch. This is one of several switches operated by the door latches, and it's wired to cause the fuse to blow if you try to operate the oven with the door open. The switch may be stuck, which can happen if the oven door gets slammed. It's also possible the switch is good but is out of adjustment.

Replacement switches are available. The Sears parts website has an exploded diagram showing where it's located (item number 30). You should let a professional make the repair, though. Microwave ovens are dangerous items to work on, and if door repairs aren't done correctly there can be excessive microwave leakage.
