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.

■ 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

NOTE: This sequence must be performed within 2 minutes.

3. Successful entry will be indicated by all UI LEDs ashing ON/OFF for a

half second and a tone will sound.

To Exit Diagnostics Mode:

NOTE: If there is no interaction for a 5-minutes period, Diagnostics Mode will timeout.

Diagnostics Mode can be exited in one of the following ways:

■ Rotate Mode Selector knob to the BAKE position, Rotate the

Off/Temperature knob to OFF position, then press Start button after 1 second. A tone will sound for successful exit.

■ Remove the AC power from the appliance.

After exiting Diagnostics Mode, the appliance will return to Standby Mode.

Navigating Diagnostics Mode

Top LEDs on

While in Diagnostics Mode, the following modes are available to be selected:

■ FAULT CODE DISPLAY

■ MANUAL DIAGNOSTIC

To select a mode, rotate the Mode Selector knob clockwise until desired mode is indicated by the UI LEDs, then press Start Button.

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.

Wi-Fi LED turned on indicates Fault (F) Display mode.

Remote LED turned on indicates Error (E) Display mode.

Knob LEDs ﬂash indicates F (Fault) or Error (E) code Numbers (#'s)

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.

Manual Diagnostics Mode:

The Manual Diagnostic Mode allows the technician to manually actuate each relay for testing purposes.

■ Enter Manual Diagnostic Mode by rotating the Mode Knob clockwise until

the mode id number is displayed by the LEDs.

■ Once in Manual Diagnostic Mode, rotate the Mode knob or Temperature

knob clockwise, to activate the corresponding relay to each element.

NOTE: For the left cavity use the same operation to enter Manual Diagnostics Mode.

Each position reached while rotating the knob will turn the elements On/Off according to the list below:

Knob Position Relay Activated

Temperature Knob - Keep Warm (Right Bake Burners) On/Off Temperature Knob - Broil Lo (Right Broil Burners) On/Off Mode Knob - Convect (Right Convect Element) On/Off Temperature Knob - Clean (Right Motorized Door Lock) On/Off Button - Oven Light (Right Cavity Light) On/Off Temperature Knob - Bread Proof (Right Convect Fan) On/Off

Knob Position Relay Activated

Mode Knob - Bake (Right Cooling Fan Lo speed) On/Off Mode Knob - Broil (Right Cooling Fan Hi Speed) On/Off

NOTES:

■ For the left cavity use the same table but use the left knob instead.

■ Mode knob only supports clockwise rotating.

■ Any new knob movement will turn the current element/burner/fan off.

In order to test the second oven cavity, follow the same test sequence and procedure.

NOTE: If no action is taken within 5 minutes, the mode times out.
