GE describes their refrigerator codes as flashing green on the display and typically accompanied by a beeping, and the range, microwave and dishwasher tables all describe codes you can read from the front of the appliance. That is the opposite of some makes, where the number is written into a hidden log and never shown — here, if something is wrong, the appliance generally tells you. Photograph what it says before cutting the power, because a reset erases it and the code is most of the diagnosis. ### Which machines this one applies to 240 Volt Advantium only. GE says plainly on their own range and oven table that they cannot list every code for every model past and present, so a code missing from their table is not proof that your appliance cannot raise it — and a code in it is not proof that yours can. The model number settles it. ### What to do about it - Clear and reprogram, then power-cycle if it returns. - Sensor-driven cooking modes are what this affects; manual modes usually still work, which is worth testing before booking. ### Where this goes next The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), and every one of those pages carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 306-2503](tel:+13053062503) and describe what the display is doing before booking anything. 240 Volt Advantium only What this one means What F4 240 Volt means, in the maker’s own words Humidity sensor on a 240 Volt Advantium — and GE words this one differently from the microwave table: here a single code covers both open and shorted, where the microwave splits them into F4 and F5.
