Which of the two you have narrows the search but not by much, because on this platform the harness fails about as often as the probe. The measurement is taken at the control end so that the wiring is included in the test, and a sensor is only replaced once the lead behind it has been cleared. ### The other ways this one is printed F30/F31 · F30 · F31 The same condition is printed differently on different panels of the same make, and every spelling the maker publishes for it is above. Whichever of them you searched for, this is the right page. ### 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 ER30D, ER36D and ER48D 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 - Note whether the oven heats at all and whether the temperature is wildly wrong rather than slightly. - The circuit is measured cold at the plug, which tests the harness and the probe together. - Heat-damaged wiring behind a cavity is replaced with the sensor rather than after it. - This is a part, not a board — a control quote for this code alone deserves a question. ### 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.
