Report "I own a Stoves DFDOa duel Fuel oven. The main oven will not totally switch off. The fan doesn't run and the on light goes out, but it is definately still on. I would guestimate that it is maintaining a temperature of approx 20 degrees. If i turn the oven off on the main switch and then back on, quite often the 'oven on' light turns on and the fan starts. To stop this i have to turn the oven knob past the off point"
