In practice this points at the wiring, a switch or a component the control watches, and the diagnosis is a matter of following what the board can see. It is not, on its own, a reason to buy a control panel — and on this make the same string is a shorted temperature sensor on the Classic ERC platform. ### 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 the model. F3 is an external problem here and a shorted sensor on the Classic ovens. - Describe what the range was doing when it appeared — baking, cleaning, or idle. - The harnesses and switches the control monitors are checked before any board is considered. - An intermittent F3 is usually a connection rather than a component. ### Where this goes next The job this usually becomes is [legacy control diagnosis](/services/legacy-control-diagnosis/), 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.
