A disconnected plug at the back of the cavity is a genuine and cheap possibility, particularly on an appliance that has been pulled out for other work; so is a lead that has finally parted after years of heat. The sensor itself is the third candidate rather than the first. ### 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 - Say whether the oven has been moved or worked on recently — a disturbed plug is a common cause. - The circuit is measured at the control end and again at the probe, which separates lead from part. - A sensor that reads open cold is replaced; one that reads correctly points at the wiring. - Where the harness has heat damage it is replaced with the sensor, not after it. ### 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.
