F9 is normally a bad door switch or door switch mount.

If you or someone you know decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa.

You can probably find exploded views and order parts by entering your model number here at the Sears parts site.

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.

F9 is almost always an error related to a bad door switch or door switch mount or misaligned door hinges.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Door switchor mount trouble can be caused by slamming the door or by opening thedoor while it's cooking without hitting the Stop pad first.

There areplastic mounts inside the microwave which hold the door switches andonto 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'sa broken tab on the switch holder, allowing the switch to rotate justout of position. This tab can be hard to see, since it is under thebottom edge of the switch.

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

If you or someone you know decide to lookinto it, we have critical information on safety, disassembly and doorswitches at our site, and our link is at our listing here on FixYa:.

SOURCE: turntable on Kenmore Elite will not turn?

The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

If you don't have your owner's manual, you can just enter your full model number at the Sears parts site.

A full Sears/Kenmore model number has 3 digits, a dot, then 8 more digits, such as ###.########

On the resulting page, look to the right for the blue "View manuals" button. Click there.

That Sears-related site has many free manuals. While the manuals they list there are all free, they will ask you to register.

Many times, the owner's manual will have the installation instructions inside.

If yours is not listed there for free, you would have to order it through the
Sears parts site.

That's where you could also order any needed parts and find handy exploded parts views.

This is usually inverter trouble, but it may be the magnetron, controller, wiring, etc.

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.

To find helpful exploded view diagrams and get part numbers, you can just enter your full model number at the Sears parts site.

Kenmore elite microwave 79203 buzzes when off


It sounds like you have a shorted cook relay on your control circuit board.

That can usually be repaired more economically than replacing the circuit board.

Kenmore Over the Range Microwave making buzzing sound and not heating


This is a strong indicator the magnetron is fried, also! this is the most expensive part to replace in the microwave oven, and in most cases cheaper to replace the whole unit.

I press #1 and hit start the blower works and light comes on but no heat


Sounds like the magnetron circuit has failed. It is the part that generates the microwaves that heat the food. It often shorts out, and makes a loud humming or buzzing noise when it fails. It's not usually cost effect to replace since the part alone can cost as much as a new oven.

Microwave won't turn on


When you say that the microwave won't turn on, can I assume that you mean that the food does not heat up! If that is the case, the problem lies with the magnetron circuit. This circuit consists of the transformer, rectifier and the magnetron, the part that generates the microwaves to heat the food. If it is the magenetron, then it probally not worth fixing since the cost to purchase the magnetron is almost as much as a new oven. To diagnose if it is the magnetron that has failed, when you turn on the oven, do you hear a louder that normal hum or buzzing sound? If that is the case, then it means that the magnetron is shorted and needs to be replaced.

Hope this helps.

Loud buzzing noise with Whirpool microwave oven when it comes on. All lights, heating and fan seems to work but not sure why loud buzzing. What is the problem?


The loud buzzing you hear is the sound of the magnatron tube.That is what emits the microwave radiation and buzzing should be normal. The mag tube may be nearing its end at witch time you will hear no buzzing and hence no heating of foods. Replacement can be costly depending on the model so most people just opt for a new one. Hope this helps

Turns on by itself and turntable does not rotate


You may have a control board issue. Thank God for safety switches.
This is a problem that an integrated circuit tech. can repair, but it may be costly.
Decide how much you want to put into this oven vs. buying a new one.

Contact me once you decide and I can help you find a service center.

Thank you,

Microwave Ultrawave with Hood fan


You are right. f4 means shorted oven temperature sensor (RTD). Check sensor harness and harness connection between oven sensor and oven control. Replace oven temperature sensor (RTD) if wiring is ok.

Kenmore ultra elite microwave hood combination


F9 code can mean something different depending upon the particular model.....
1.) IF your Microwave uses "UltraWave technology"/"SmartWave technology"...Then either the Magnetron has failed or the Inverter board has failed OR maybe the control board has failed (HUH?).
2.) IF your Microwave does NOT use "UltraWave technology"/"SmartWave technology" then one or more of the door switches has failed.

** "UltraWave technology"/"SmartWave technology" **
I'll explain a few things about this wonderful technology...
The control board (accepts the pushbutton commands) has to talk to the inverter board to tell it how much power should be applied to the magnetron. The inverter board will then power the magnetron and inform the control board if the magnetron is working OK.
If there is something wrong with the magnetron or inverter board or a there is a communication breakdown between the control board and the inverter board...WA-LA-----F9----

A pretty reliable test for the Magnetron is to operate the oven and listen for a ticking sound 5-6 times about a second apart. If you can hear the ticking....The magnetron has failed..if no ticking, the control or inverter board failed.

Note: This 'technology' may come in other flavors as well

High pitched hum/buzz


By high-pitched, you mean it is not that same frequency as when it's cooking? Is the tone near or the same as the beep you hear when you press a key? Please post a little more information so we can help better.
