WARNING
Electrical Shock Hazard Only authorized technicians should perform diagnostic voltage measurements. After performing voltage measurements, disconnect power before servicing.
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.
Failure to follow these instructions 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.
IMPORTANT: Electrostatic Discharge (ESD) Sensitive Electronics ESD problems are present everywhere. ESD may damage or weaken the electronic control assembly. The new control assembly may appear to work well after repair is finished, but failure may occur at a later date due to ESD stress. ■
Use an antistatic wrist strap. Connect wrist strap to green ground connection point or unpainted metal in the appliance -ORTouch your finger repeatedly to a green green ground connection connection point or unpainted metal in the the appliance.
■
Before removing the part from its package, touch the antistatic bag to a green ground connection point or unpainted metal in the appliance.
■
Avoid touching electronic parts or terminal contacts; handle electronic control assembly by edges only.
■
When repackaging failed electronic control assembly in antistatic bag, observe above instructions.

Diagnostics To Enter Service Mode:
Before proceeding with any corrective action, disconnect power and perform the following checks: A potential cause for 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 h aving a ■ sensitivity of 20,000 ohms per volt DC or greater. Check all connections before replacing components, looking for ■ broken or loose wires, failed terminals or wires not pressed far enough into connectors. Damaged harnesses must be entirely replaced. Do not rework harness. Voltage checks must be made with all connectors attached to the ■ boards. Resistance checks must be made with the power supply ■ disconnected or the power cord unplugged from outlet and with wiring harness or connectors disconnected.

The left rear burner Power Level ind icator will reflect the “F” code, lighting a number of LEDs according to the current fault that is shown. For example, the code “F6” will light 6 Power Level LEDs on the left rear burner. “F0” “F0” will light all 10 indicators. The right rear burner Power Level indicator will reflect the “E” code, lighting a number of LEDs according to the current fault that is shown. For example, the c ode “E6” will light 6 Power Level LEDs on the right rear burner. “E0” will light all 10 indicators. The left front burner Power Level indicator will reflect the current error code index. For example, the first error code will light one LED, the second error code will light two LEDs, etc. Only the last 10 error codes will be displayed. To cycle between error codes, p ress the left front ON button. Afte r reaching error code 10, it will go back to error code 1 if ON is pressed again. To clear all error codes in the memory, press and hold the left front OFF button button for 3 seconds. seconds.

Connect ohms measurement equipment to terminal 4 and terminal 2 at the element winding. 4. Confirm ohms reading is 45.7Ω ± 5%. If it is not, go to Step 5. If it is, go to Step 6. 5. Replace the element. 6. Replace all parts and panels before operating. 7. Plug in cooktop or reconnect power. 8. Verify operation is normal.

FOR SERVICE TECHNICIAN’S USE ONLY Voltage and and Ohms Reading Reading Table NOTE: If NOTE: If the violet jumper wires at P2-1 and P2-2 and the orange wires at P2-3 and P2-4 on the appliance manager are not connected, the User Interface will allow commands to be entered but the elements will not function. To check for proper voltage, complete the following steps: 1. Disconnect power. 3. Reconnect power and confirm voltage reading. 2. Connect voltage measurement equipment. 4. Disconnect power after performing voltage measurement. Feature
