My Whirlpool oven will not broil or bake. This happened once before and I changed the temp sensor. This time the oven quit during a cleaning cycle.I replaced the sensor again but it did not help. The control panel seems to be working. Any thoughts?

Denman if you're out there, I checked the thermal switch (o ohms) checked continuity on bake and broil elements (both are showing resistance), as you know the temp sensor is brand new, and I checked continuity in the door lock switches. Everything has checked out fine. With the power on, the clock works, the control panel reads and shows the oven to be preheating when you set it to bake but nothing heats up. Am I down to the control board being bad or is there something else to try first? Thanks again
