It is the current platform’s equivalent of the Classic F3 and F4 pair, with one code instead of two, and it is diagnosed the same way: the circuit is measured at the control end so the harness is included, and the probe is replaced only once the wiring behind it is clear. ### Where this appears, and which table it belongs to On the appliance’s own display. Photograph it before you cut the power: a display that has been cleared has taken the evidence with it, and there is no way to ask the machine for it again. Then check the model, because this make changed hands in 2016 and the two generations share no code string. The same characters mean different things on a Classic ERC oven, an ER-series range and a Modernist induction cooktop, and a meaning read off the wrong table is worse than no meaning at all. ### Which machines this one applies to Modernist wall ovens and Pro ranges. The same number on a different appliance of this make is a different page and often a different repair, which is why this archive is organized by appliance rather than by number. This maker documents codes on 5 of the appliance types this site publishes — coffee machine, cooktop, dishwasher, oven and range — and publishes none at all for freezer, microwave, range hood, refrigerator and wine cooler. Those appliances have symptom pages here and no code pages, which is the honest answer rather than borrowing a table from the machine next door. ### What to do about it - Stop using the oven — a control that cannot read the cavity should not be heating it. - Note whether the problem appears cold or only once the oven is hot; the second points at a lead. - The circuit is measured at the plug, which tests probe and harness together. - This is a sensor-class repair rather than a board one. ### Where this goes next The job this usually becomes is [oven temperature sensor service](/services/oven-temperature-sensor-service/), and that page 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, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 363-6067](tel:+13053636067) and describe what the panel is doing before booking anything.
