Troubleshooting Procedures

To avoid risk of electrical shock, personal injury or death; disconnect power to cooktop before servicing, unless
testing requires power.
• Verify proper grounding before checking for trouble.
• Be careful of the high voltage circuit.
• Do not touch any part of the circuit on the printed circuit board, since static electric discharge may damage the
control panel. Always touch yourself to ground while working on this panel to discharge any static charge built
up on your body.

Electronic Touch Control Troubleshooting

Symptom
No element operation (power
board disables power to
elements)
LOCKED LED illuminated,
electronic control locked when
power applied (dual, triple or
bridge elements not selected),
no audible alarm
No LEDs, electronic control
locked, 1 audible beep
2 LEDs flash, (user must lock
cooktop to evoke this display),
no element operation, no
audible alarm
3 LEDs flash, electronic control
locked, 1 audible beep
6 LEDs flash, electronic control
locked, no audible alarm
7 LEDs flash, electronic control
locked, no audible alarm
8 LEDs flash, electronic control
locked, no audible alarm
9 LEDs flash, electronic control
locked, no audible alarm
10 LEDs flash, electronic control
locked, no audible alarm
11 LEDs flash, electronic control
locked, no audible alarm
12 LEDs flash, electronic control
locked, no audible alarm
All LEDs flash, no element
operation, 3 short audible beeps
(continuous**)
*Control Board resets the Power Board every 15 seconds.
**Audible alarm (beeps) will not occur if all elements are turned off.

WARNING
!
CAUTION
Possible Cause
Communication failure.....................................
(power board disables power to elements
after 10 second communication loss
between control board and power board)
Checksum failure (control board) .................... • Replace control board.
ON LED failure (control board)........................ • Replace control board.
Hardware watchdog error (power board)......... • Replace power board.
Redundant OFF key input line is not
operating properly (control board) ................... • Replace control board.
A/D failure (control board) ............................... • Replace control board.
Shorted temperature probe (power board) ......
Shorted input (power board)............................
Open temperature probe or open input
(power board) .................................................. • Verify sensor resistance.
A/D failure (power board) ................................ • Replace power board.
RAM test failure (power board)........................ • Replace power board.
Checksum failure (power board) ..................... • Replace power board.
Communication failure (control board*)........... • Verify connections.
Over temperature indication ............................
Multiple keys detected (control board),
shorted key......................................................

Correction
• Verify power to unit.
• Verify power to power board.
• Check connection between power
and control board.
• Verify sensor resistance and
connections.
• If symptoms persist, replace
power board.
• If symptoms persist, replace
power board.
• If symptoms persist, replace
control board.
• Verify sensor resistance.
• If symptoms persist, replace
control board.
