Frigidaire Cooktop Error Code E24

E24 on a Frigidaire cooktop means the lock key sensor has been detected as defective. This sensor is part of the right front cook zone touch control and is responsible for enabling and disabling the control lock function. The cooktop's internal diagnostics flagged the sensor as non-functional or out of range. The problem may be in the wiring, the touch panel itself, or the main control board.

Using the cooktop with an active E24 error is not recommended. A defective lock key sensor may cause the control lock function to behave unpredictably, leaving the cooktop either permanently locked or unable to engage the lock. This could create a safety hazard, particularly in households with children. Resolve the fault before returning the appliance to regular use.

Repair costs vary depending on which component has failed. If only a wiring connection needs to be reseated, the cost may be limited to a service call fee, typically in the range of $75 to $150. Replacing the touch control panel generally costs between $100 and $300 for the part, plus labor. A main control board replacement can range from $150 to $400 or more for the part, depending on the specific cooktop model.

Some E24 errors can be resolved without replacing parts if the cause is a loose cable or contamination under the touch panel. Start by disconnecting power to the cooktop, then inspect the ribbon cables and harness connectors on the main power and right front cook zone touch control for any loose or corroded connections. If the error returns after reconnecting and restoring power, the touch control panel or main board likely needs professional replacement.

A power reset by turning off the breaker or unplugging the cooktop for several minutes may temporarily clear the E24 code, but it will return if the underlying cause has not been addressed. If the lock key sensor or its wiring is genuinely defective, the fault will reappear once the cooktop runs its diagnostics again. A reset is useful for confirming whether the issue is intermittent or persistent.
