I did put this in oven in the forum a little while ago but cant find it now, basically the oven and grill work fine on all settings but once the cust turns the oven off via the selector (and this only happens on the oven) within a couple of minutes or so the electrics trip.
The oven has a fan with a plastic blade on the top in black ducting and also a tubular sort fan down the back. Could it be the cut outs that stops these after cooling at the end? there seems to be a screw in cut out in the ducting and one (if your facing the back of the oven) to the left.
Any help/ideas would be really appreciated.
Ollie.
