The control sees an impossibly low resistance — which reads as an impossibly high temperature — and refuses to heat. A short is more often the harness than the probe: a wire pinched against the cavity when a rear panel went back on, or insulation that has gone brittle where it passes a hot corner. The pair is worth reading together, because which of the two appears decides whether the technician brings a sensor or opens the back first. ### 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. ### 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. Shorted Probe. Please reset the range by disconnecting the power to the unit for up to 30 seconds. You can disconnect power by either unplugging the unit or flipping the circuit breaker off and back on.
