FOR SERVICE TECHNICIAN S USE ONLY

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. W10478476A

IPC: Induction Power Control Board NTC: Negative Temperature Coefficient Acronyms and Abbreviations Failure/Error Codes UI: User Interface Board If all the lights on one or both of the EGO cooktop controls are off and there is no response from the cooktop, complete the following steps: 1. Disconnect power. 7. Replace all parts and panels before operating.. Check the wires and connector P3 to the right cooktop control. Check 8. Reconnect power. the wires and P9 connectors on both of the EGO cooktop controls. 9. Check that it is working. If it is not, go to Step 10. 3. Reconnect power. 10. Disconnect power. 4. Check that it is working. If it is not, go to Step 5. 11. Replace the left cooktop EGO control board. 5. Disconnect power. 1. Replace all parts and panels before operating. 6. Replace the right cooktop EGO control board. 13. Reconnect power. 1. Ensure that both cooktop (EGO) controls are OFF (idle mode).. Touch OFF>OFF>ON for the selected control. The power level LEDs for the rear and front elements will light up. 3. Touch ON to display the first error code if it is not already displayed as a series of bars. To interpret the display to identify the error code, refer to the EGO Cooktop Control Error Code Display section. 1. The top and bottom displays will light the single and dual circles (element indicators) sequentially as well as, a number of bars.. When the single circle is displayed, the bars represent the F code. When the dual circle is displayed, the bars represent the E code associated with the F code. Diagnostics Mode for Cooktop Controls EGO Cooktop Control Error Code Display 4. Touch ON to display the next error code (10 may be saved in memory). 5. Touch and hold the ON key for 5 seconds to clear the error codes. 6. Touch OFF to exit the Diagnostics Mode. Diagnostics Mode will automatically take a time-out to the idle state after minutes. Repeat Step to return to Diagnostics Mode. 3. Bars on the top display represent tens, so three top bars are 30. Bars on the bottom display are 1s, so six bottom bars are 6, thus the total displayed in this case is 36. If the number of bars remains the same as the single and dual circles sequence, the error code is F-36 E-36. 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 1 Failure type 1 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-1 E-1 Coil under current Type 1 1. 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 3. 3. 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 8. 8. Replace the power control board. 9. Replace all parts and panels before operating. 10. Reconnect power. F-1 E-00 Supply power frequency Type 1. 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 60 Hz.

Service Code Shown on Display Failure Description Type of Failure Repair Suggestions F-5 E-5 Stuck fan on power control board (right or left side fan, depending on which side of the display the failure is on). Type 1. 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. 10. Replace the power control board. 11. Replace all parts and panels before operating. 1. Reconnect power. F-36 F-37 E-36 E-37 Temperature sensor is not working Type 1 1. Disconnect power.. Check that the temperature sensor is between 184,000 Ω and 9,000 Ω at room temperature and is firmly plugged in. If the sensor is not between 184,000 Ω and 9,000 Ω, replace the coil and go to Step 5. If the sensor is between 184,000 Ω and 9,000 Ω and the electrical connection is good, go to Step 3. 4. 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 E-XX Power control board failure error where XX will describe one of 13 possible causes. The repair suggestion is the same in all cases. Type 1 or Type 1. 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.
