1 Tech Sheet Do not discard DANGER WARNING Electrical Shock Hazard Only authorized technicians should perform diagnostic voltage measurements. After performing voltage measurements, disconnect power before servicing. Failure to follow these instructions can result in death or electrical shock. Electrical Shock Hazard Disconnect power before servicing. Replace all parts and panels before operating. Failure to do so can result in death or electrical shock. Voltage Measurement Safety Information When performing live voltage measurements, you must do the following: Verify the controls are in the off position so that the appliance does not start when energized. Allow enough space to perform the voltage measurements without obstructions. Keep other people a safe distance away from the appliance to prevent potential injury. Always use the proper testing equipment. After voltage measurements, always disconnect power before servicing. W044306A

2 PC: Power Control Board NTC: Negative Temperature Coefficient Acronyms and Abbreviations Failure/Error Codes UI: User Interface board If all the lights on the User Interface are Off and there is no response from the cooktop, complete the following steps:. Disconnect power. 8. Replace all parts and panels before operating.. Check the continuity of the fuses on the EMI board. If one or more of 9. Reconnect power. the fuses is blown, replace with a new fuse. 0. Check that it is working. If it is not, go to Step.. Disconnect power.. Change the User Interface. 5. Check that it is working. If it is not, go to Step Disconnect power. 7. Change both power control boards. There are 3 types of failures associated with the cooktop. The description of these failures and the impact they will have on the rest of the cooktop are listed in the following. Failure Type Failure type comes from the power control board. This failure will affect only one burner. The user may continue to use the other burners. Failure Type Failure type usually comes from the power control board (there could be some exceptions). These failures affect all burners associated with that power control board; the user may continue to use the burners that belong to the other power control board. Failure Type 3 Failure type 3 comes from the User Interface. This failure disables the entire cooktop. When this type of failure occurs, all the burners are switched Off by the User Interface. Service Code Shown on Display Failure Description Type of Failure Repair Suggestions F- Coil under current Type. Disconnect power.. Check for the correct connections at TA - TB or T3A - T3B on the power control board (whichever connection the burner is plugged into). If connections are correct, go to Step Replace the burner coil. 4. Replace all parts and panels before operating. 5. Reconnect power. 6. Check for proper operation. 7. If everything operates, end service. If error code still appears, disconnect power and go to Step Replace the power control board. 9. Replace all parts and panels before operating. 0. Reconnect power. F- Supply power frequency Type. Disconnect power.. Replace the power control board. 5. If the issue is not fixed, contact a qualified electrician to verify the frequency of the home power supply is. F-5 Stuck fan on power control board (Right or left side fan, depending on which side of the display the failure is on.) Type. Disconnect power.. Check that the cooling fan connector is firmly plugged in. 5. If the issue is not fixed, disconnect power. 6. Replace the cooling fan. 7. Replace all parts and panels before operating. 8. Reconnect the power. 9. If the issue is not fixed, disconnect power. 0. Replace the power control board.. Replace all parts and panels before operating.. Reconnect power.

3 Service Code Shown on Display Failure Description Type of Failure Repair Suggestions F-36, F37 Temperature sensor is not working Type. Disconnect power.. Check that the temperature sensor is between 84,000 Ω and 9,000 Ω at room temperature and is firmly plugged in. If the sensor is not between 84,000 Ω and 9,000 Ω, replace the coil and go to Step 5. If the sensor is between 84,000 Ω and 9,000 Ω and the electrical connection is good, go to Step Reconnect power and check that the coil is working. If it is not working, disconnect power and replace the non-working coil and the power control board. 5. Replace all parts and panels before operating. 6. Reconnect power. F-40 Power control board failure Type or Type. Disconnect power.. Check that the cable between the User Interface and the power control board is not damaged and is firmly plugged in. 5. Verify if error is still present. If yes, disconnect power. 6. Replace the power control board. 7. Replace all parts and panels before operating. 8. Reconnect power. F-4 Power supply Type. Check for 40 volts AC at the main incoming power supply connection by completing the following steps.. Disconnect power. 3. Connect voltage measurement equipment. 4. Reconnect power and check for 40 volts at J L to N, and then J L to N at the EMI filter board, and then J L to N at both power control boards. If voltage is correct, disconnect power, replace the power control board and go to Step 5. If voltage is not correct, disconnect power and check for an open fuse on the EMI filter board. If there is not an open fuse, have a qualified electrician check the home power supply. 5. Replace all parts and panels before operating. 6. Reconnect power. F-47 Power supply from power control board to User Interface is missing or WIDE communication error between UI and power control board or an open fuse on the filter board Type. Disconnect power.. Check that the cables between the User Interface and the power control board are not damaged and are firmly plugged in. 4. Reconnect power and check that it is working. If it is not working, disconnect power and replace the cables between the User Interface and the power control board. 5. Replace all parts and panels before operating. 6. Reconnect power and check that it is working. If it is not working, go to Step Disconnect power. 8. Check the continuity of the fuses on the EMI board. If either of the fuses is blown, replace with a new one. 9. Replace all parts and panels before operating. 0. Reconnect power and check that it is working. If it is not working, go to Step.. Disconnect power.. Change both power control boards. Check that it is working. If it is not working, go to Step Disconnect power. 6. Change the User Interface. 7. Replace all parts and panels before operating. 8. Reconnect power. F-56 Wrong or invalid configuration Type 3. Disconnect power.. Replace the User Interface. F-58 Wrong or invalid configuration Type. Disconnect power.. Replace the power control board. 3
