Hello Tony,
F116 is the fault code indicating that the heater is not heating. As per the tech sheet, you should: (1) Check all heater, sensor, and wire harness connectors. Make sure they are tight and secure. Check heater ribbon for possible damage. (2) If fault persists, replace power board WB23T10014. (3) If fault persists, replace main board WB27X33352 and recalibrate inductive sensors. If a new board is installed and the cooktop is operated prior to calibration, F161 will appear in the timer display until the calibration procedure has been successfully completed. NOTHING IS WRONG WITH THE NEW BOARD. Cooktop must be cool before beginning calibration. Make sure all the "Hot Lights" have turned off before beginning calibration. Procedure: Calibration of the inductive sensors must begin with the LF surface element and proceed in a clockwise direction around the cooktop. ALL OF THE SENSORS MUST BE CALIBRATED TO COMPLETE THE CALIBRATION PROCEDURE. Step 1: Clear EVERYTHING from the top of the glass. Step 2: Lock the control by pressing the CONTROL LOCK key for 3 seconds. The CONTROL LOCK LED will turn on. Step 3: Enter TECH mode by pressing the TIMER ON/OFF, LF+, and LR+ keys at the same time. The timer window will flash the words TECH MODE. Step 4: Begin the calibration procedure by pressing the TIMER ON/OFF, LF+, and RF+ keys at the same time. The timer window will flash CAL and the LF power level display will flash the U symbol. Step 5: AFTER the timer window displays DISC and U symbol stops flashing, CENTER the aluminum disk (provided with service parts) on the LF surface element. Step 6: Press the PAN and LF+ keys at the same time. The electronic control will perform the calibration on the LF sensor and then proceed to the LR sensor. If the sensor calibration is successful, the timer window will flash CAL and the U symbol will flash in the LR power level display. If an error occurred, F will display in the power level display. Do not try to recalibrate that sensor. Continue the calibration procedure for all sensors and then diagnose the problem as described below. Step 7: Repeat steps 5 and 6 for the LR, CR (if present), RR, and RF surface elements, always pressing the PAN and LF+ keys to calibrate. Step 8: After the RF surface element has been calibrated, the Timer window will display a PASS or FAIL message for the entire calibration procedure. If the calibration procedure fails, F will be displayed in the power level display of any sensor that failed the procedure. Step 9: Exit the calibration procedure by pressing the PAN and RF+ keys, and then follow the steps below to recalibrate. If the Calibration Procedure is Interrupted: If the calibration procedure is interrupted for any reason, exit the calibration procedure by pressing the PAN and RF+ keys at the same time. This will exit the calibration procedure and return the control to TECH mode. Calibration may be started again from TECH mode. If the Calibration Procedure Fails: Failure of the calibration procedure may occur due to a defective main board, inductive sensor, or the connection between the board and the sensor. If the calibration procedure fails, attempt to calibrate the cooktop again.
F152 is the fault code indicating a heater is over-temperature. The tech sheet covers this as: (1) Check all heater, sensor, and wire harness connectors. Make sure they are tight and secure. Check heater ribbon for possible damage. (2) Measure resistance across the heater ribbon at the heater terminals. Resistance should read from 20-80 Ohms. If it does not, replace the heater and recalibrate the inductive sensors. (3) If fault persists, remove sensor connector from the board and measure RTD resistance. Should read from 1030-1150 Ohms (46¥F-102¥F).If it does not, replace the heater and recalibrate inductive sensors. (4) If fault persists, replace power board. (5) If fault persists, replace main board and recalibrate inductive sensors.
Since the components are the same as suspected causes, the above instructions still apply.
