In most cases, that means a bad door switch or loose door switch mount.

But if you'll post your brand and full model number we can probably narrow it down further.

If you or a friend 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:

    That's funny that MicrowaveSvc is saying that it is likely a bad door switch or loose door switch mount. Almost every other response I've seen for F9 error state that it is either a magnetron or inverter problem....most likely stating it is an inverter problem.
    A magnetron costs around $74 and an inverter costs $168 to replace...not including the cost of labor.

Error message econ

I appreciate your post, friend!

Based off the information you have provided your Electrolux built in microwave is displaying an error code of "ECON". I am showing that this is an invalid error code. I would recommend you perform a reset on your microwave and you can do that by disconnecting the power cord for roughly ten minutes. If that does not help correct your issue I would suggest contacting a professional technician for proper diagnosis and repair. This will help you avoid any unnecessary part purchases. -Matt

Code f 7

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 should cover an F7 error code.

A video is available here showing how to remove a typical over the range control panel assembly in under 5 minutes.

F7 Error Code On Microwave Ovens With Inverter Board
MODELS: GH9177XL, GH9185XL, MH9180XL, MH7155XMS, & KHHS178L for example

An F7 error code could be an inverter board failure. Anything else that prevents microwave energy may also cause an F7 error, and must be checked. The technician should perform the following procedure to test for an F7 error code:

1. Check the magnetron.
2. Check the magnetron TCO (it should be closed).
3. Check the 3 interlock switches.
4. Check the harness wiring.
5. Check the electronic controls.
6. Check the inverter board.

I recommend that you bookmark that link to your favorites.

?E - 5" message

From Samsung's FAQs:

"Some models are equipped with a sensor that can automatically adjust the oven's heating time based on the amount of steam in the oven. If your microwave is displaying E1, E4, or E5, there may be an issue with the gas sensor. For an E1 error, press the Cancel button and check on the food.

"Other microwaves do not give specific error messages and just display "8888" on the LED. If you get this error message, your microwave needs service.

"If the message is either ERROR or E-6, it indicates a mechanical fault.

"For all error indications, including the SE or 5E error, try unplugging the microwave from the outlet for at least ten minutes and then plug it back in. If the error persists, the microwave may require service. Please use our ASC Locator to find your nearest Authorized Service Center."

Or instead let us know if we can help further.

Sharp 930-cs starts fine after 10 or 20 seconds it stops heating, stops spinning & Error message on the display. I replaced the turntable motor but problem continues.

When the Absolute Humidity (AH) sensor is defective (open or short), ERROR will appear in the display after 16 seconds.

If ERROR appears check sensor wire connections and/or AH sensor.

We have the service / repair manual for this model and have uploaded it to our site here to help you.

It will give you safety info, step by step help in disassembly, troubleshooting tips, and the Sharp part numbers, most of which interchange except cosmetic parts.

Error code F3H on model GH5184XP

F3H is a humidity sensor error.

You may be able to clear the error by unplugging the oven for a couple of minutes. Then plug it back in, reset the clock and try again.

If it still has the error after a reset, please write back so we can give you another suggestion.

F-9 Error after running a few seconds...

If this is a "SmartWave" branded microwave oven then F9 is an error that indicates an inverter board or magnetron has failed. Either way.. Try this...With the F9 error cleared, start the oven and listen for a ticking sound. The inverter will attempt to 'fire' the magnetron 5 times.(ticking sound). If can hear ticking, replace magnetron....Else in may be a door switch problem
