Diagnostics
Unplug range or disconnect power before performing the following checks:
■ Make sure there is power at the wall outlet.
■ Has a household fuse blown or circuit breaker tripped? Was a regular
fuse used? Inform customer that a time-delay fuse is required.
■ A potential cause of a control not functioning is corrosion on connections.
Observe connections and check for continuity with an ohmmeter.
■ All tests/checks should be made with a VOM or DVM having a sensitivity
of 20,000 Ω per VDC or greater.
■ Check all connections before replacing components, looking for broken
or loose wires, failed terminals, or wires not pressed into connectors far enough. Damaged harnesses must be entirely replaced. Do not rework a harness.
■ Resistance checks must be made with power cord unplugged from
outlet, and with wiring harness or connectors disconnected.
■ If the oven does not heat, there may be a problem with connections to
the power supply. Check the connection to L2.
■ When removing AC power, allow time for the main control (ACU) to
completely power down. At a minimum, leave AC power removed for one minute.
IMPORTANT: Do not replace the control if there is no evidence of any failure. There are two service diagnostics modes implemented on the Main (right for
double oven models) user interface board including: Fault Code Display and Manual Diagnostic modes.
To Enter Diagnostics Mode:
Before proceeding with any corrective action, perform the following steps to enter the Diagnostics mode:
With the appliance in standby mode, perform a sequence of 6 movements using the Mode Selector knob.
1. To start the movements, the knobs shall consider as initial position, Bake
for the Mode Selector knob and Off for the Temperature knob.
2. Turn the Mode Selector knob.
one position; pause for 2 seconds
one position; pause for 2 seconds
one position; pause for 2 seconds
one position; pause for 2 seconds

Fault Code Display
Manual Diagnostics
Top and right LEDs on
NOTE: You must exit the current mode in order to access and navigate to the other available modes.
Fault Code History Mode:
This mode provides the ability to check the last ten faults stored in the memory. Because the UI utilizes LEDs and a speaker for communication, errors are displayed through specic LEDs to indicate the fault and error code (F# E#) format.
■ The Wi-Fi LED turns on to indicate that the fault (F) code number (#) is
being displayed.
■ The Remote LED turns on to indicate that the error (E) code number (#) is
being displayed.
■ The eight LEDs of the back-lit Mode Selector knob ash ON/OFF to
display the fault and errors code numbers (#’s). A number is represented by the number of times the LED ashes ON/OFF. For example to display “F5”, Wi-Fi indicator will be ON and the Mode Selector knob LEDs will ash ON/OFF ve times.

FOR SERVICE TECHNICIAN’S USE ONLY
■ Errors stored in the memory will be displayed from the most recent
occurrence to the oldest.
■ The Fault (F) Wi-Fi LED turns ON and the knob LEDs ash the
corresponding number (#). Then the UI is blank for a half second before displaying the Error (#) code.
■ There is a 1 second delay between each fault/error code (F# E#).
■ Errors will continue to be displayed until the mode is exited or the mode
times out.
■ If there are no additional errors in the memory (OR if there are no errors
at all), the speaker will tone 3 times and the rst error will be displayed again.
NOTE: If the error (E) number is zero (“0”), then only the fault (F) number is displayed for that code.
To clear: After review, the stored error codes can be cleared out or erased. To clear all error codes, press the Start button once.

This test measures the function of the cooling fan including the resistance at low and high speed to determine if there is a connection or fan motor issue. Additionally, it provides a method to test the hall effect sensor feedback.
Resistance Tests:
1. High/low speed cooling fan -
motor check
2. Hall sensor feedback circuits in
board - circuit/connection
Function Tests:
1. High speed cooling fan -
mechanical or other failure
2. Hall effect sensor - determine if
sensor failed
3. Low speed cooling fan -
mechanical or other failure
1. Unplug range or disconnect power. Measure the cooling fan connection on the main control
ACU. Measure the low and high speed resistance values and compare to expected values. High Speed between J6-4 and J5-3 and compare to High Speed Resistance (21±5 Ω). Low Speed resistance between J7-2 and J5-3 and compare to Low Speed Resistance (29±5 Ω). If both low and high resistance values are within range, then go to step 5. If either are out of range, go to step 2.
2. Remove back panel, check the connection to the cooling fan, and measure resistance on cooling
fan connector. High Speed Resistance should be present between black and white wire and Low Speed Resistance should be present between red and white. If not present, replace the cooling fan.
