Frigidaire Cooktop Error Code E94

The E94 error code on a Frigidaire induction cooktop indicates an internal communication failure within the 2-cook-zone induction module. Specifically, the error points to a breakdown in data communication between the filter board (connector X58) and the generator board (connector X10) inside that module. The induction generator board is responsible for producing the high-frequency alternating current that drives the induction coils, while the filter board conditions power input and facilitates control signals. When communication between these two boards is interrupted or corrupted, the module cannot operate safely and triggers E94 to shut down the affected zones.

The most common origin of this fault is a loose, damaged, or disconnected cable running between the X58 connector on the filter board and the X10 connector on the generator board. Vibration during cooking, improper reinstallation after previous service, or manufacturing tolerances can all allow this cable to work loose over time. In some cases, the cable itself may have sustained physical damage such as pinching, fraying, or heat exposure, which degrades signal integrity. Beyond the cable, a failed generator board or filter board can produce the same communication error if the boards themselves are unable to exchange data even when the cable is intact.

Diagnosing E94 begins with a careful inspection of the cable and both connectors at X58 and X10. The cable should be fully seated at both ends with no signs of corrosion, burning, or mechanical damage. If the cable checks out, the next step is to evaluate whether either board has visible damage such as burnt components, swollen capacitors, or heat discoloration. Replacing the faulty board is typically required if the cable and connectors are confirmed to be in good condition.
