Hi, I have an IGNIS AKL901/1X oven. It no longer heats up! I have tested the elements with a multimeter and found no continuity with the combined grill/oven element. I have replaced the element but still have the same fault. You can select any heating mode and temperature but when the OK button is pressed you get the 2 tone beep low to high but the light/heat/fan does not come on. The light is fine as this can be switched on solely for aesthetics.
