KitchenAid KHMS 2050 SSS, doesn't heat up and indicates "Error Code F7, VH SMPS feedback, 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.

The link to the PDF document (Adobe Acrobat Reader) with the warranty information is at the bottom of that page.

The document with the warranty information provides a toll free phone number to call. It is provided near the end of the text.

How can you take the fuse out on this model KHMS 155LSS-4 of kitchenaid

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.

F7 problems are usually caused by poor connections. I suggest to unplug the ribbon connector off the control board and cleaned the copper connectors using alcohol or with a pencil eraser. If that does not work the touch pad may be defective.
