IMPORTANTElectrostatic Discharge (ESD)

Sensitive ElectronicsESD problems are present everywhere. ESD may damage orweaken the electronic control assembly. The new controlassembly may appear to work well after repair is finished,but failure may occur at a later date due to ESD stress.

Use an anti-static wrist strap. Connect wrist strap togreen ground connection point or unpainted metalin the appliance

-OR-Touch your finger repeatedly to a green groundconnection point or unpainted metal in theappliance.

Before removing the part from its package, touchthe anti-static bag to a green ground connection pointor unpainted metal in the appliance.

Avoid touching electronic parts or terminal contacts;handle electronic control assembly by edges only.

When repackaging failed electronic controlassembly in anti-static bag, observe aboveinstructions.

DIAGNOSTICSDisconnect power and perform the following checks:

A potential cause of a control not functioning is corrosion onconnections. Observe connections and check for continuitywith an ohmmeter.

All tests/checks should be made with a VOM or DVM having asensitivity of 20,000 ohms per volt DC or greater.

Check all connections before replacing components, lookingfor broken or loose wires, failed terminals, or wires not pressedinto connectors far enough. Damaged harness must beentirely replaced. Do not re-work a harness.

Voltage checks must be made with all connectors attached tothe boards.

Resistance checks must be made with power cord unpluggedfrom outlet, and with wiring harness or connectorsdisconnected.

NOTES:

Always disconnect power before touching internal parts of theoven.

Upon replacement, immediately return old electronic ovencontrol using the mailing label supplied with each new control.

FAILURE/ERROR DISPLAY CODESBefore proceeding with any corrective action, perform the followingsteps to enter the Diagnostic mode.

1. Enter Diagnostics mode and verify error codes by pressingOFF, OFF, START.

2. If control does not enter Diagnostics, repeat steps.

D. Replace all parts and panels before operating.E. Plug in oven or reconnect power.F. Verify operation is normal.G. If error occurs again, go to step H.H. Unplug oven or disconnect power.I. Replace the upper/lower appliance manager.J. Replace all parts and panels before operating.K. Plug in oven or reconnect power.L. Verify operation is normal.

F7 E3 UNPROPER FILTER RESET

PROCEDURE: Before proceeding, press OFF, OFF, START to enter the Diagnosticmode. Then press ERROR CODE on the display relevant to the oven cavity thatwas showing the failure to verify the error codes. In the following procedure,where "upper/lower" is written, refers only to the cavity that was showing thefailure.A. Verify that the water system is connected with the product. If so, go to step B.B. Check the filter and verify that water is present in the water plumbing system.

If so, go to step C.C. Unplug oven or disconnect power.D. Replace the filter.E. Replace all parts and panels before operating.F. Plug in oven or reconnect power.G. Empty the water system by disconnecting the tubing from the boiler and

collecting the water in at least a 1 liter reservoir. Be sure water doesn't dropon electrical components. Reconnect the water tubing and check connections.

H. Press OFF, OFF, START to enter the Diagnostic mode. Then pressERROR CODE and CLEAR ALL. Enter the Diagnostic menu again and pressRELAY ACTIVATION, MORE, FILL VALVE and ENGAGE on the upper ovendisplay. Ensure that relay energizes and fill valve is operating. When the waterlevel status changes from LOW to HIGH press RELEASE. Wait at least 60seconds.

I. If error occurs again, press OFF, OFF, START to enter the Diagnosticmode. Press STATUS SCREEN, STEAM SYSTEM, and NEXT to display theWater Quality Sensor (WQS) reading.

J. Verify Water Quality Sensor (WQS) reading is less than 446.K. Unplug oven or disconnect power.L. Replace the conductivity sensor.M. Replace all parts and panels before operating.N. Plug in oven or reconnect power.O. If error occurs again, press OFF, OFF, START to enter the Diagnostic

mode. Press STATUS SCREEN, STEAM SYSTEM, and NEXT to display theWater Quality Sensor (WQS) reading.

P. Verify Water Quality Sensor (WQS) reading is less than 446.Q. Unplug oven or disconnect power.R. Replace the user interface.S. Replace all parts and panels before operating.T. Plug in oven or reconnect power.

MESSAGE/DESCRIPTION


F7 E4 CONDUCTIVITY SENSOR NOT CONNECTED

PROCEDURE: Before proceeding, press OFF, OFF, START to enter the Diagnosticmode. Then press ERROR CODE on the display relevant to the oven cavity thatwas showing the failure to verify the error codes. In the following procedure,where "upper/lower" is written, refers only to the cavity that was showing thefailure.A. Verify that the water system is connected with the product. If so, go to step B.B. Check the filter and verify that water is present in the water plumbing system.

If so, go to step C.C. Unplug oven or disconnect power.D. Open the back panels and make sure the P9 connector on the user interface

is fully inserted.E. Make sure the connector on the conductivity sensor is fully inserted.F. Verify the conductivity sensor, visually inspect the 4 wires between P9-1, 3, 5,

and 6 on the user interface and respectively pin# 1, 2, 3, and 4 on theconductivity sensor. Make sure wires are not cut or pinched. If the wires appearto be intact, perform a continuity check between P9-5 and P9-6 on the userinterface. Perform a continuity check between P9-1, 3 on the user interface andpin# 1, 3 on the conductivity sensor respectively. The measure should be lessthan 5 Ω.

If any of these measurements exceeds 5 Ω, replace the harness andgo to step G.If all the measurements are less than 5 Ω, replace the conductivity sensor.

G. Replace all parts and panels before operating.H. Plug in oven or reconnect power.I. Verify operation is normal. If error occurs again, go to step J.J. Replace the user interface.K. Replace all parts and panels before operating.L. Plug in oven or reconnect power.M. If error occurs again, replace the user interface.

OVEN STRIPCIRCUITS

The following individual circuits are for use in diagnosis, and are shown in the ON position. Do notcontinue with the diagnosis of the appliance if a fuse is blown, a circuit breaker is tripped, or if there isless than a 240 volt power supply at the wall outlet.

NOTES:

Strip diagrams are the same for upper and lower cavity.

Both blowers are on, no matter which cavity is currentlyworking.

The right appliance manager controls the upper cavity, and theleft appliance manger the lower.
