I'm getting the F4E2 error on my kitchenAid Microwave/Oven. It says internal sensor error.Oven is working but microwave just displays the F4E2 error.
Answer Hello Nir,
As per the tech sheet:
PROCEDURE: There are three sensors for the microwave. They are the Convection Thermistor, Ambient Sensor (integrated on the MW appliance manager), and Humidity Sensor. Before proceeding, press OFF, OFF, START to enter the Diagnostic mode and verify the error codes.
A. Press the number "6" key to transition to the Sensors screen.
B. Verify in diagnostics the temperature readings on sensor.
C. The sensors for the combo microwave oven will scroll through the list of sensors.
D. If a sensor reading on the display shows (---) dashes, the sensor is not connected or otherwise inoperable. If sensor that shows dashes is the ambient sensor, proceed to step O.
E. Unplug oven or disconnect power.
F. Remove top panel to gain access to the microwave control system.
G. Ensure the convection thermistor (P6) and the humidity sensor (P4) are plugged in properly to the appliance manager. If not, plug in the connector and proceed to step R. If connectors are plugged in proceed to step H.
H. Visually inspect the wires between P6 and convection thermistor from the appliance manager to the back of the unit to ensure they are not pinched or cut. If wires appear to be intact, unplug connector and proceed to step I.
I. Measure the indicated sensors resistance value from the P6 connector. For this sensor, the resistance value should read 231 kO at 25°C.
J. Visually inspect the wires between P4 and humidity sensor from the appliance manager to the front of the unit to ensure they are not pinched or cut. If wires appear to be intact, unplug connector and proceed to step K.
K. Measure the indicated sensors resistance value from the P4 connector. For this sensor, the resistance value should read 2.8 kO at 25°C (between pins 3 and 1 or between pins 3 and 2).
L. If indicated temperature sensor does not meet these requirements proceed to step M.
M. Replace convection thermistor. Ensure the convection thermistor is properly inserted and plugged into P6. Continue to step P.
N. Replace humidity sensor. Ensure the humidity sensor is properly inserted and plugged into P4. Continue to step P.
O. Replace microwave appliance manager. Ensure all connectors are properly placed and firmly connected.
P. Replace all parts and panels before operating.
Q. Plug in oven or reconnect power. Wait for 60 seconds.
R. Enter into the Diagnostic mode and press key "6" to scroll to the sensor display. Read the sensor reading for the three sensors, ensuring they are reading correctly.
Note: This question is for the older version of this part, but we thought you might still find it helpful
I get a "communications error F6eo" I was told that this is the part to correct the issue, is that true???
Answer Jeff, The F6E0 code, could be due to a bad control, but, You need to make sure you have 240 VAC at the oven terminal block, " Most F6-E0 code complaints have been due to loose connections and absence of L2 from the house power supply. "verify that 120 VAC is present between P1-1 and P1-2 of the microwave appliance manager board." If there are no loose wire connections, between the control boards ansd you have the correct voltages, then replace the control. Thanks and Good Luck.
