C-20 covers both ways the oven sensor can go wrong while the oven runs: an open circuit or a short. Either way the control has no believable temperature to hold the oven to. Dacor range display What to do when C-20 shows on the range ### Kind of code Temperature sensor The oven sensor sent a reading the control would not accept, or one that climbed well past the setting. A loose plug or a sensor that has drifted is ruled out before the control board, and a temperature that keeps rising means the range is switched off at the breaker first. ### Usually leads to Temperature sensor and thermostat repair A range oven that bakes hot, bakes slow, takes forever to preheat or posts a sensor code, traced to the sensor probe, the thermostat or the calibration. ### Shows up as Range Oven Temperature Wrong Recipes burn or come out underdone, and an oven thermometer disagrees with the temperature set on the range. ### Make Dacor A Samsung-owned luxury brand that sells professional-style gas, dual-fuel and induction ranges. ### Source Dacor 30-inch Transitional gas range user manual, troubleshooting Dacor Transitional gas and dual-fuel ranges. ## Before you book, in this order. Each step comes from Dacor's own guidance for C-20 on its ranges. Follow it to the end: the last card says whether this is a visit. 01 Turn the knobs to OFF and restart; if C-20 persists, cut all power for at least 30 seconds and reconnect. 02 If it comes back, stop using the oven for anything temperature-critical and book a visit. ### Still there?

Book with the code and the model number. ### What not to do C-20 is the cavity sensor, not the meat probe; Dacor gives the probe its own code, C-23. ## What you may notice with it.

Turn the knobs to OFF and restart; if C-20 persists, cut all power for at least 30 seconds and reconnect. If it comes back, it needs a visit. ### My Dacor shows C-20 but the oven still gets warm. Is it safe to bake? The oven may heat, but with the sensor reading open or shorted it cannot hold a set temperature, so results are unpredictable. Use the range top instead and book a visit. ### Is C-20 on a Dacor the same as the probe code? No. C-20 is the sensor inside the cavity; the plug-in temperature probe reports as C-23. Removing the probe will not clear C-20. --- **[Read on the site: Dacor range showing C-20 | RangeRepair.center](https://rangerepair.center/error-codes/dacor-range-c-20/)** **[Book a visit with RangeRepair.center](https://rangerepair.center/schedule/)**
