Whirlpool Induction Cooktop Displaying "Loc": How to... | appliancefaults.com

Technical Background:

The 'Loc' feature is a child safety lock that disables the cooktop controls to prevent accidental activation. The cooktop's Microcontroller Unit (MCU) monitors the touch sensor inputs. When the lock function is engaged, the MCU ignores most user inputs, maintaining the 'Loc' display. Deactivating the lock typically involves a specific sequence recognized by the MCU. Voltage paths related to the touch sensors and MCU must be functional for proper operation.

Symptoms:

The Whirlpool induction cooktop displays 'Loc' on the control panel, and the cooktop is unresponsive to touch commands. The homeowner is unable to use the cooktop.

Possible Causes:

Accidental activation of the child lock feature.
Prolonged pressing of the lock button.
Software glitch in the cooktop's MCU.
Stuck or faulty touch sensor on the control panel.
Power surge causing temporary malfunction.
Defective control panel assembly.

Solution:

1

Visually inspect the control panel for any signs of damage, spills, or debris.
2

Locate the lock symbol or button on the cooktop control panel.
3

Press and hold the lock button for 3-5 seconds until the 'Loc' display disappears. Some models require a longer press.
4

If the touch controls are unresponsive, disconnect power to the cooktop at the breaker panel. Wait 60 seconds and restore power.
5

Test all cooktop elements to ensure proper function after disabling the child lock.
6

If the 'Loc' code persists, verify the ribbon cable connection between the control panel and the main control board.
7

If the issue remains, replace the control panel assembly. Use a 1/4-inch nut driver for panel screws.

Safety Warning:

Disconnect power to the cooktop at the breaker panel before attempting any repairs. Lockout/Tagout (LOTO) procedures should be followed. High voltage is present when the cooktop is powered on.

Prevention:

Periodically clean the cooktop surface to prevent debris buildup on the control panel. Avoid prolonged pressing of buttons on the control panel. Protect the cooktop from power surges with a surge protector.

Expert Tip:

Some Whirlpool induction cooktops have a service mode. Simultaneously press and hold the '+' and '-' buttons for 5 seconds to enter service mode. This might allow you to clear the error code. Consult the service manual for your specific model.
