Frigidaire Cooktop Error Code E19

The E19 error code on a Frigidaire cooktop indicates that the control system has detected a fault in the right front zone control key sensor. This sensor is part of the touch control interface, which uses capacitive sensing technology to register user input for the right front cooking zone. When the sensor fails to return expected signals or produces readings outside the acceptable threshold, the cooktop's control board logs E19 and typically disables the affected zone to prevent unintended operation.

The root cause is most often a defective touch control panel assembly rather than a problem with the underlying heating element or power supply. The capacitive key sensor can degrade due to moisture infiltration behind the glass surface, physical damage to the touch interface, or internal component failure within the control board circuitry that manages the right front zone. Contamination from spilled liquids that seeps beneath the cooktop surface is a particularly common trigger, as it can create false capacitance readings or short the sensor circuit.

Because the touch control and the main power board for the right front cook zone are integrated in many Frigidaire cooktop designs, the prescribed first diagnostic step is to replace the main power and right front cook zone touch control assembly. Before replacing the assembly, technicians should inspect the sensor area for visible moisture, debris, or burn marks. If the surface is contaminated, thorough cleaning and drying may be attempted, though a persistent E19 code after cleaning almost always requires a full control assembly replacement.
