Error code F7. How can we fix the problem?
SOURCE: Whirlpool Velos Microwave showing "Error
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.

1. Check the door, hinge and cavity front alignment. Adjust as needed.
2. Check the operation of all interlock switches.
3. To check the over-temperature protection for the magnetron, unplug
microwave oven or disconnect power.
4. After 40 seconds, check to see whether this solves the problem.
5. If this solves the problem, check the cooling fan for proper operation or
blockage.
6. Unplug microwave oven or disconnect power.
7. Check resistance of the magnetron thermostat. It should be close to
0 ohms. If necessary, replace magnetron thermostat.
8. Check that the control cable to the 1100 watt inverter is correctly connected
to plug P2 on the display PCB. If necessary, adjust or reconnect.
9. If interlock switches operate correctly, replace 1100W inverter.
10. If problem persists, replace electronic control.
11. Plug in microwave oven or reconnect power.

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.

Hello, and thanks for using FixYa.
On whirlpool microwaves yes its a microcontroller board failure aside from replacing the board a skilled technician with previous experience might be able to repair the board for you instead of replacing it.
seems like the part goes for 155$ as new. but is currently out of stock.
