SOURCE: Will run for about 18 seconds,then gives an F7 error code

>No, the service guy did none of the things you suggested.

Just as I suspected...

The "element" as it is so inaptly misnamed in the case of this warranty document, is actually the "magnetron", which should normally have an extended warranty beyond the normal 1-year (I assume) parts and labor warranty anyway.

The magnetron may be the culprit here, but a thorough check of the points on my previously posted list is in order to determine the actual cause of the problem.

Since your husband is an engineer, I would suggest that he invite a colleague over to help and to provide some backup for any heavy lifting if it should need to be removed from the wall.

Safety first after all!

You can download Kitchenaid Whirlpool owner's manuals and installation instructions here in case it needs to be taken down during troubleshooting.

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.

If you don't find yours, or if you want to look at it without disassembling the oven, you can download it here.

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.

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

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

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.

There is a technical sheet inside the unit.

On it you'll find help locating components and a chart which shows the "F" codes. F7 is likely either a door code or an inverter failure.

F7 call for service


Hi, the F7 = HV SMPS feedback error. Most of the time this is a costly microprocessor board issue but can be something as simple as a loose or broken wire.

If it is in fact new you should contact Whirlpool for warranty service. Anything you would do as a consumer will void the warranty.

My new Whirlpool Microwave oven is now showing an F7 on the screen and will only turn on for 3 seconds. What should I do?


Hi and welcome to FixYa, I am Kelly.

The F7 = HV SMPS feedback error. Most of the time this is a costly microprocessor board issue but can be something as simple as a loose or broken wire.

If it is in fact new you should contact Whirlpool for warranty service. Anything you would do as a consumer will void the warranty. First make sure your microwave is registerd via this link where it says "Register your product" http://www.whirlpool.com/custserv/index.jsp

Then using that same link you can schedule service or find out where your nearest carry in service center is.

Whirlpool gold Microwave stopped working displays F7 code


For replacement parts - head on over to PartSelect.com or RepairClinic.com and enter in your full model number for a full parts listing.
I recommend both sites because ...


FixYa has no affiliation with either site - I have been using and recommending them for years - trouble free.

PartSelect has a great schematic database for locating the part on your unit and great "testimonials" for each part that often times includes HOW-TO information.
RepairClinic has pictures of each part they sell and also a great how-to and troubleshooting for basic repairs.


If your unit has never been serviced - there should still be an original service manual enclosed in plastic taped to the inside of the shell.
In the service manual are Error codes, maintenance procedures, and troubleshooting steps you can follow.


Anything too complicated or beyond your scope should be handled by a professional.

If you think you want to tackle the repair - and have gotten stuck on a step - reply to your question and I will be glad to help you out.

F7 ERROR CODE ON GH6177XPS


This is a known problem with this unit, and whirlpool has put out a Service Flash out on this. The reason this is happening is Electrical circuit interruption between the L1 and Neutral in the microwave invert circuit. This has to be addressed by a Tech.

Whirlpool Velos Microwave showing "Error F7 HV SMPS Feedback" error. What does that mean?


F7 means that the control panel is not getting feedback from the Switched Mode Power Supply (high-voltage inverter).

This could be due to a problem with the inverter or the control unit / circuit board, but it appears to be the latter in most cases.

We repair microwave control boards for customers nationwide with our guaranteed $39.95 service.

We have full details, plus critical safety, disassembly, and troubleshooting info at our site. You'll find a link to our site in our listing here on FixYa: http://tinyurl.com/yzjozk

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.

You may reply back with your brand and model number if you'd like us to look into this further, or feel free to contact me directly if you need more help.

We're happy to help and we appreciate your thoughtful rating of our answer.
