Display EXPLANATION AND RECOMMENDED PROCEDURE
F6E4 Control Status
Oven User Interface UI and ACU state status mismatch.
Possible Causes: Problem with the main oven control. Can occur within 60 - 120 seconds of the fault condition when the UI and ACU
status mismatch.
Recommended Procedure: See TEST #14 (UI & ACU Mismatch) on page 31.
F6E6 Main Oven Control Connection
Possible Causes: There may be a problem with the main control or the associated wiring. Can occur within 60 - 120 seconds of the
fault condition when communication between the ACU and HMI is lost.
Recommended Procedure: See TEST #2 (Communication of Main control (ACU)) on page 18.
F6E9 Left Oven Control Connection
Possible Causes: There may be a problem with the main control or the associated wiring. Can occur within 60 - 120 seconds of the
fault condition when communication between the ACU and REB is lost.
Recommended Procedure: See TEST #3 (Relay Expansion Control Board (Left Oven)) on page 19.
F8E0 Main oven Cooling Fan speed low or Not Functioning
Main oven Cooling Fan speed too low (fan speed below 500 rpm).
Possible Causes: The fan is spinning too slowly or there is a problem with the Hall Effect sensor. Can occur within 60 - 120 seconds of
a fault condition when cavity temperature is above 349°F (176°C).
Recommended Procedure: See TEST #10 (Main Oven (Right) Cooling Fan) on page 27.
F8E1 Left Oven Cooling Fan Speed Low
Main oven Cooling Fan speed too low (fan speed below 500 rpm).
Possible Causes: The fan is spinning too slowly or there is a problem with the Hall Effect sensor.
There may be a problem with an airow restriction, the left oven cooling fan, the left oven control, or the associated wiring. Can occur
within 60 - 120 seconds of a fault condition when cavity temperature is above 349°F (176°C).
Recommended Procedure: See TEST #11 (Secondary (Left) Oven Cooling Fan) on page 29.
