On Maytag combination microwave-ovens, the F1Ex family points to a microwave user-interface or control fault (or its wiring). The specific "non-volatile memory failed" meaning is not confirmed in Maytag documentation — treat F1E2 as a control/UI fault and confirm the exact sub-meaning for your model.
