One carries the panel you press; the other throws the relays that put current through the elements, and every number in this family says the same thing — a message was sent and nothing came back. Thermal cycling loosens a plug, a ribbon wears where it bends, or a board simply stops replying. This maker publishes **three** numbers where the sister badge publishes two: F26 appears on its range guide and nowhere in the sister’s. The distinction matters only to whoever is ordering the part, which is exactly why it belongs on the page. ### The other ways this one is printed F3 / F20 / F26 · F3 · F20 · F26 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 why not to clear it On the appliance’s own display, as a short single code — a letter and a number, or two letters. Nothing alternates and nothing arrives in halves on this make, so what the panel shows is the whole of it. Photograph it before you cut the power. This maker’s own answer to most of these is thirty seconds at the breaker, and that is worth following once — but a display that has been cleared has taken the evidence with it, and there is no way to ask the machine for it again. ### Which machines this one applies to Electric 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. ### What to do about it - Photograph the display before anything else. A code copied by hand loses its spacing, and on this make the spacing is part of it — SU dS and SB SB are not typing errors. - Give it a full thirty seconds at the breaker rather than a flick. These controls hold enough charge to carry their own state across a short interruption, which is why a quick off-and-on appears to do nothing. - Set the same task going again and watch exactly when the code lands — at the first press, part-way through a preheat, or twenty minutes in. That timing narrows down the board faster than the number on its own ever will. - One reset is a test; four is a habit, and a habit hides how often this is actually happening. Note the date each time instead. A code that turns up weekly and a code that turns up twice a year are two different conversations. ### Where this goes next The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), 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) 912-9018](tel:+13059129018) and describe what the panel is doing before booking anything.
