As mentioned...have you confirmed correct power is comming to the unit?
220-240 volts AC from black to red, 110-120 volts AC from black to white or red to white.
Checked out the oven sensor and fuse on the back and they are ok
Sensor is more for temp and normally won't stop the oven from working....how was the thermal fuse checked?
Juice going into the control panel is ok. Any way to check out the control board.
Power comming in, turn on oven and check for power comming out.
