Kathryn - For model number JCB840SK2SS
November 10, 2025
Oven temp declines a lot from setting eg, set at 350 degrees, will go down to 255 and food not done in expected time
Hello Kathryn, thank you for contacting us. According to our research, you will need to replace the temperature sensor, part number PS11729628, to fix this issue. The temperature sensor measures the oven's internal temperature. If it's malfunctioning, it might send inaccurate readings to the control system. Good luck with your repair.
