Frigidaire Cooktop Error Code E23

E23 means the cooktop's control system has detected a defective keep warm key sensor in the right front cook zone touch control panel. The sensor is either sending an out-of-range signal or not responding at all. The fault can be caused by loose wiring, moisture damage, or a failed sensor or control component.

It is not recommended to continue using the cooktop with an active E23 fault. A defective sensor could potentially cause the keep warm zone to behave unpredictably. The cooktop should be serviced before regular use resumes to avoid any risk of unintended heating.

Repair costs vary depending on which component is at fault. If only a 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 or main control board can bring the total repair cost to somewhere between $150 and $400 or more, depending on parts and labor rates in your area.

Some E23 faults can be resolved without replacing parts by inspecting and reseating the flex cables and connectors between the touch panel and the main control board. If the connections are secure and clean and the error persists, the touch control panel or main control board will need to be replaced, which requires moderate technical skill and comfort working with appliance electronics.

A power reset, such as turning off the circuit breaker for one to two minutes and restoring power, may temporarily clear the display. However, if the underlying sensor, cable, or connection fault is still present, the E23 code will return during the next operation cycle. A reset alone is not a repair.
