The oven won't heat up the grill works ok along with the oven light/control panel display/and both temp/power indicators work as normal. i have tested the oven element and temperture switch with a multimetre and both are ok, time display is ok and no timers are set. I have traced the wiring but don't know what indication (on my multi metre) I should get after it goes/leaves the control panel/oven fuction switch. I think it is the oven funtion switch but could you confirm this.
