SOURCE: Error Code

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.

SOURCE: F7 Error code on Kenmore

On the tech insert found in a cavity under the cover of my Kenmore MHC, the F7 code means the inverter board ($90 - $130 street price Fall 2008) is bad and needs replacement. I am having this problem, and verified that the magnetron was not shorted to ground with an ohm meter. I verified with a volt meter that the magnetron was not getting any voltage applied across the cathode from the inverter board when the microwave is running ("WARNING"- don't do this test with the magnetron connected.) I have an inverter board on order.

SOURCE: Works for approx 30 secs then it cuts off with a error Code F7 message.

Assuming yours is a model KHMS2050SSS0, here is what the technical sheet says about the F7 error code:

1. Unplug microwave oven or disconnect power.
2. After 40 seconds, check to see whether this solves the problem.
3. Unplug microwave oven or disconnect power.
4. Check cooling fan operation
5. Check the magnetron.
6. Check P65 connection on the relay control board.
7. Check the P56/P66 connection between relay board and relay control board.
8. Check wiring to the 1200W inverter and control system. See “Checking Inverters.”
9. Check operation of all interlock switches.
10. Replace all parts and panels before operating.
11. Plug in microwave oven or reconnect power.
12. Check voltage at 4903-1 on relay board. If it is 120, unplug microwave oven or disconnect power.
13. Replace inverter.
14. Replace all parts and panels before operating.
15. Plug in microwave oven or reconnect power.
16. If problem persists, unplug microwave oven or disconnect power.
17. Replace relay control board.
18. Replace all parts and panels before operating.
19. Plug in microwave oven or reconnect power.
20. If problem persists, unplug microwave oven or disconnect power.
21. Check for reversed plug connection on controls or loose wiring.
22. Replace all parts and panels before operating.
23. Plug in microwave oven or reconnect power.

(This troubleshooting guide presumes one does not know how to test electronic components. That's why they say to replace and part and check it again.)

SOURCE: 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.

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.

I have a Kenmore Elite Speedcook Microwave oven, model #665.63783600. What does error code F7 mean on this model?


F7 Error Code On Microwave Ovens With Inverter Board

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.

For more free help, feel free to contact me via my site with your detailed symptoms and full model number and FCC ID number as shown on the tag in or on the oven.

How CAN i TEST MY MICROWAVE?


Most common cause of an F7 code on these models is a bad inverter or magnetron. Generally it is best to replace both the magnetron and the 1100 watt inverter board at the same time, since a bad magnetron is usually what burns out the inverter board.

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.

Error F7


Microwave will not operate (cook). F7 error code
appears on the display.
Electrical circuit interruption between L1 and Neutral in
the microwave inverter circuit.
Possible reasons:
1. Check door, hinge and cavity front alignment and adjust
as needed.
2. Check the operation of all interlock switches.
3. Check over temperature protector for the magnatron.
4. Check all Cavity Thermostats for closed circuit.
5. Unplug the oven for at least 40 seconds. If this solves
the problem
A. Check the Cooling Fan for proper operation or
blockage
B. Check the resistance of the magnetron thermostat.
It should be 0 Ohms, replace if necessary.
6. Check that the control cable to the 1100 watt inverter
is properly connected to plug P2 on the display PCB
& Adjust or Reconnect
7. If interlock switches operate correctly, replace 1100W
inverter.
8. If problem persists, replace control assembly.
