What not to do

F40 concerns the sensor built into the oven, not the probe you push into food. A probe problem shows as Probe Error F50 instead.

Questions
about F40.

Can I clear F40 myself?
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.

Back to your everyday

Still showing F40?

Book with the code written exactly as the stove shows it, the full model number, and whether you notice any smell of gas or hot wiring — when there is a code, that is where the diagnosis starts.
