We installed kitchen aid microwave convection oven model kems308. it is displaying error code F6E0, "Lost communication". Any idea on how to fix?

Unit has to be removed from wall top panels removed to replace if can live with out it great bulb is cheap labor 100-150

Hi,

This fault is a communication error at the appliance manager, could be a loose wire or a bad display transformer, either way you will need a certified technician to fix this issue, there is no simple plug and go issue to resolve. I personally found the problem to be the transformer not send voltage to the appliance manager. This is solvable but needs someone who understand electronics to correct this issue.

F6 E0 Oven user interface - lost communication E6 Oven appliance manager 1 (upper, single) - lost communication

This is directly from the tech sheet of your oven and directly from the factory web site.

Good Luck

Hello Inna,
Here is the link to that users manual https://www.whirlpool.com/digitalassets/MLPDF/User%20Instructions%20-%20W10170438A.pdfyou can click on it to download it

Hi,

Below is the complete instruction sheet.

You are having a communication error between the appliance. Here is the actual tech manual instructions for that code:

PROCEDURE: Before proceeding, press OFF, OFF, START to enter Diagnostic

mode and verify the error codes. Ensure AM software, UI software and EEPROM

CHECKSUM versions appear on the lower text line. If AM software and EEPROM

versions do not appear, UI and AM may not be communicating. Verify this for the

lower oven UI and for the microwave (upper oven) UI. The lower oven UI will show

the AM software version for the lower oven appliance manager, and the microwave

UI will show the AM software and EEPROM versions for the microwave appliance

manager.

If the lower oven UI is not displaying the AM software version, go to UI IS NOT

DISPLAYING AM SOFTWARE VERSION.

If the upper oven UI is not displaying the AM software and EEPROM versions,

go to UPPER OVEN UI IS NOT DISPLAYING THE AM SOFTWARE AND

EEPROM VERSIONS.

If lower oven UI and microwave UI are both displaying an error, go to LOWER

OVEN UI AND MICROWAVE UI ARE BOTH DISPLAYING AN ERROR.

UI IS NOT DISPLAYING AM SOFTWARE VERSION:

A. Unplug oven or disconnect power.

B. Open the back panels and make sure the P6 and P2 connectors are fully

inserted on the appliance manager and on the lower oven user interface board.

- If they are not plugged in, plug in connectors and go to step F.

- If they are plugged in, go to step C.

C. Visually inspect all wires between P6 on the appliance manager and P2 on the

lower user interface.

- Make sure wires are not cut or pinched.

- If the wires appear to be intact, perform a continuity check between

P6-1 of the appliance manager and P2-1 of the user interface board.

Complete for P6-2(AM) to P2-2(UI), P6-4(AM) to P2-4(UI) and P6-5(AM) to

P2-5(UI). All the measurements made should be less than 5 ?. If any of

these measurements exceeds 5 ?, go to step E.

D. Replace the appliance manager. Ensure all connectors are properly inserted.

E. Replace the wiring harness (signal). Ensure all connectors are properly inserted.

F. Replace all parts and panels before operating.

G. Plug in oven or reconnect power.

H. Observe for longer than 1 minute to determine if error has been repaired.

I. If error does not appear, initiate a bake cycle. Let the cycle run for at least

1 minute.

- If no error occurs, cancel the cycle, the problem has been repaired.

- If error occurs again, restart the troubleshooting procedure at step A.

At step D, replace the lower oven user interface board if appliance

manager has already been replaced.
- If both are replaced the problem has been repaired.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

I assume it's a KitchenAid that you have. Here you can find a previous thread about this code:

F6 E0 means the switch pulse return line to the electronic control is not connected

The usual way to correct this is to replace the electronic control (clock).

You might want to check for loose or burnt out wires on the clock unit before replacing tho'.

That is where the vent is. You should feel some hot air there. If you do not feel the air that is the time to worry. If you have any other questions please feel free to ask.

Last night I saw the lights in the house flicker momentarily... This morning, I turned the oven on, set it to Bake and within a few seconds, the control panel reported error code “F6 E0” then shut the oven off. The control panel also reported "Lost communication...". I read on another site that this code may require replacing the control panel itself. Apparently, the momentary power fluctuation wasn't large enough to damage the electronics (since the control panel still works), but was significant enough to confuse the electronics controlling the oven. To fix the oven, I simply turned the 30 AMP breaker for the oven off for about 5 minutes. When I turned it back on, the oven worked just fine. Solution #1 recommends taking off the control panel, which voids the warranty. It's more likely that it was fixed just by cycling power to the oven via the breaker.

The F-3 error code typically means you have sensor problem. The sensor is usually mounted in the oven space up near the top of the unit. The first thing to do is turn off the circuit breaker to the oven. Do you have an ohm meter? I suggest if you don't to purchase one. They are relatively inexpensive. Maybe you can borrow one from a friend. Disconnect the sensor from the electronic control and measure the resistance. There should be a wiring diagram in the top of the unit that will help you to locate the sensor wires. Most sensors should read around 1100 ohms at room temperature. If sensor reads as an open circuit or has a very high resistance, it must be replaced. If instead it reads very low, then there is a short in the wiring. Some units have a fuse in series with the sensor. Check to see that the fuse has not blown.
