Please follow this steps and fix it. God bless you


  1. Inspect the power cordUnplug the power cord and check for voltage at the outlet. Also inspect for damage, shorts, or burn marks that can be a possible safety hazard.
  2. Bad door switchIf your microwave does not work at all and you know everything is plugged in properly and the outlet is functioning, then also check the door hooks and the door release button. Using a volt-ohm meter on RX1, check your terminals. When your microwave door is closed you should have a reading of zero. Once the door is open the reading should change to infinity. If these readings do not match up, replacement of the door switch is necessary.
  3. Blown fusesTo determine if your fuse has blown out, which may attribute to your microwave not running, you need to pull the fuse out using a pair of fuse pullers. Lay it down and using a volt-ohm meter on RX1, check both ends of the fuse in question. If you do not get a reading of zero, then you will need to replace the fuse.
  4. Bad fan motorLocate the fan and remove the leads. Again using the volt-ohm meter on RX1, check the terminals. If an infinity reading is displayed, it means that the fan has gone bad and requires replacement.

Why does my kenmore microwave have power in but does not work?


Really need more information - what do you mean it "does not work"? Do you have any lights or display showing? Does it run and make sounds like it's working but it just isn't heating? Or is it completely dead? Each symptom indicates a different problem.
If it's completely dead, then it's either a fuse or a TCO (Thermal CutOff device - a thermal fuse, usually located above the cooking cavity).
If you've got a display, but it doesn't "run" when you press Start, then it is probably a door interlock switch.
And if it runs and makes noise (especially if the noise is louder than normal), then it is probably the magnetron tube.

Inspect foil side of HV board for burned tracks toward lower side of board. If burned, check HV capacitors (High Voltage Capacitor Test Procedure) and HV transformers (High Voltage Transformer Test) for a short. Otherwise test other components as outlined above.
Solution: Replace defective components as necessary. If applicable, repair foil trace on HV board.
Hope that helps.........

Microwave wont start shows door on display


When it shows a door error and won't start, that's usually a door switch or door switch mount. My help file on door switches is here.

BUT - assuming your model is the KEMS308SSS01,02,03,04, or 05, it is probably the type that has the overdesigned door sensor circuit, as shown in the diagram below:

12_27_2012_8_49_05_pm.jpg

In this case, the other likely culprits (besides the door switch) are the 20A fuse, the 15A fuse, the "cavity TOD ("thermal overload device" - thermal cutout / thermostat) and the magnetron TOD.

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 also contains the diagram above.

There's a YouTube video available showing how to remove a typical over the range control panel assembly in under 5 minutes. mini_manual_behind_grille_small.jpgdee77f7.jpg

Accessing the oven cavity TOD for testing and possible replacement will require you to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

I have a sharp 1900 w/r 24 at microwave, display shows a single green dot, when switched on at the wall I just hear a normal sound as if the unit is operating but nothing works


In this case as the display does not show a clock then it seems the program controller is not working correctly. So check power - step down supply, if the pads are responding- if not faulty pads. Also the door switches, if the switch contact are not good then it will not trigger the processor to switch on the waveguides. If the lights or fan work without any display or action of program being triggered to start then it can be a possible fault on the main board or the processor. Sometimes insect secretion can short the board and display panel and so the processor can work in such an erratic manner. If so clean,solder and reset the board.

Now identify the parts by clicking this link: http://www.espares.co.uk/advice/microwave/a/5/141/identifying-microwave-parts.html

Now unless the display works and the processor starts to switch on the MAGNETRON , the table and light will also switch on as it must heat.

So it is necessary to check the main controller unit as it seems to be the suspect..

I have a Maytag OTR Microwave oven that doesn't work. After I close the door and set the time and start, I see the time countdown, but I don't see the microwave starting. I can get the microwave to start,...


This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.

See our file on door switches here.

My kitchenaid microwave/convection oven shows "DOOR" on display


This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.

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 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.

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.

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.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you only need a switch, you can order a universal type here for $5 postpaid.

My over the stove whirlpool microwave shuts off and keypad will not work shows F2 on the display... pressing of door sometimes makes it come back on


sounds like the door interlock switch or the linkage on the door that activates the switches. Don't know your knowledge, you get to them by opening the control panel, if it's over 5 years old I wouldn't put any money in it, I imnagine it's made by Samsung in Korea.
