SOURCE: Kitchen Aid ovens - error codes

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.

Turn the power to the oven off. It usually is not possible to unplug the power chord for the built-in appliances so go to the main switch board and just turn off the oven power for about 5 minutes and then turn on the switch. The error code should disappear. Mine did!

Getting error code 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.

Hope this helps.

Shortly after end of 1 year warranty, KEMS378SSS04 began displaying F6E0 Lost Communication on lower over UI (not on the microwave). Turning power off/on (multiple times required sometimes) fixes the...


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!!

Microwave oven will not start - no power


The oven may shut off if the control board detects a problem such as a failed temperature sensor. The control will typically display an error code when this happens. Look for an error code in the display when the oven shuts off.
Another chance will be power failure or a weak breaker could be shutting off the oven. An electrician may need to check the breaker to check for proper power.
Hope this helps.

What does f3 mag mean on the display?


F3: Magnetron Current Low

Fault is displayed when the current transformer

(CT) on the I/O control board does not detect

enough current. The fault is monitored when the

microwave is on during a cook cycle or self-test.

The fault is cleared from the display at the onset of

a cook cycle if the CT detects current or when the
magnetron is successfully energized in Test Mode

My kitchenaid 30" built in microwave/convection oven beeps all the time. I have to turn the power off to stop the beeping. when i turn the power on the beepeing starts. I am able to use the microwave...


Hi there,

Well is there any error code on the digital display of your Microwave/oven?
Do you mean how to keep it from beeping when you press keys, or is it beeping by itself?
If the microwave oven is coming on or doing anything (beeping) by itself, this is very dangerous and can result in a fire.
First of all you cam leave it unplug for half hour, it helps you to reset your microwave/oven. If further you have the same problem please reply to the questions.......

Good Luck!!

Thanks

New oven won't work and can't set time, display keeps blinking


Hey--  You've spent a bunch of time on this already, so let's figure it out. The first step is to check power connections. L1, L2 , Neutral for proper location and tight connections. Should have 120v and 220v checked at bus block. If these check out, then this new unit should be under warranty and qualify for service. Not unheard of bad board or loose wire on a new unit. Let a tech sort it out on site. Let me know if this info helps- have more if needed-  Thanks-  Ed
