Switch the oven off and wait for it to cool. If it comes back, it needs a visit. ### Why is my BlueStar oven baking unevenly with F40 showing? The control is not getting a trustworthy temperature, so it cannot switch heat on and off at the right moments. ### Can I keep baking on my BlueStar stove with F40? Results will be off. The burners are fine to use while you wait for the sensor to be tested. ### Is F40 on a BlueStar stove the sensor or the wiring? BlueStar calls it a sensor issue; the technician still checks the plug and wire along with the sensor. --- **[Read on the site: BlueStar stove showing Control Error F40](https://stoverepair.center/error-codes/bluestar-f40/)** **[Book a visit with StoveRepair.center](https://stoverepair.center/schedule/)**
