It is one of the most straightforward problems on this platform: a part with a known resistance curve, measured cold and compared against a table. What is worth knowing is that the harness fails about as often as the sensor — the run behind a cavity is a hot place for a wire, and a chafed lead reads exactly like a shorted probe. ### 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 Classic ERC wall ovens and 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 still heats at all; a shorted sensor usually stops it. - The measurement is taken cold, at the plug, so the harness is included in the test. - A sensor and its harness are quoted together where the wiring shows heat damage. - This is a part rather than a board — do not accept a control board quote for this code alone. ### 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.
