Hello, my name is***** be patient whilst awaiting any responses as I'm not constantly available.Can you supply the full ENr & FD of the appliance please
OK thank you.. There should also be similar information on a label or plate surrounding the oven orifice.. I shall however endeavor to find your appliance with the information given.I shall come back to you once I have found the information relating to your apliance
Thank you... Your appliance ENr is F3460N0/01 and is dated as May 2006..A moment or two please whilst I investigate what the problem could be from the diagrams available
Rob, can I ask... If after the oven restarts, you then heat it to 200 degs, does it then trip out once more, or does it continue to a higher degree of heat?
OK.. Next question is.. does this happen on both ovens
OK.. thanks... Does this happen only on fan assisted setting?
OK... I am going out for a hour or so.. I shall return to this question on my return
OK Rob, In that case can you check that the fan at the back of the oven is operating well and not just rotating slowly
Then we have a few more suspects to look at.. the cavity cooling fan, thermal limiter, and the clock are now being discounted as the problem does not arise during cooking by convection ovenThis leaves only two possibilities (Element and Selector switch) but only one suspect in my mind, a faulty fan element, breaking down in the insulation as it reaches higher temperatures
Yes sir I do... I would have concurred with your thoughts of the safety thermostat / thermal limiter / fire safety device being at fault however, since the problem is not occurring when the convection oven is operating then I have ruled this out
Ask the electrician to do an insulation test on the element.. This may show a leak... but then if you heat until trip then the element will undoubtedly show a leakage
Rob; Having further checked the diagrams .. I have changed my oping inon.. I will consider the thermal limiter a probable cause as it is placed on the rear wall of the oven.. Check this for its temperature cutout limit of 170 deg C .. If it is operating at that temperature, then either you have a leak in the insulation of the fan element or the fan is not distributing the heat fast enough and is causing the element to heat up the back panel of the cooker
I must also warn you that a faulty thermostat could also cause this, as the temperature would increase above the specified limit of the oven operation.. I would use a multimeter to check its operation
Resealing is no a consideration on my mind
We can test some of the items together if you have the right equipment.. do you have this?
OK.. firstly.. swap the thermostats back to where they should be.. No doubt they operate at different temperatures or have different properties.The scorching of the thermal insulation is normal to a degree.. don't worry too much about this..What I would do in this instant is to place a digital thermometer lead into the area in the back panel where the thermal cutout is.. as soon as the trip occurs, turn on the thermostat to check the temperature and SWITCHING OFF the mains at the oven switch, use a multi meter to check the operation of the thermal cutout and also check the heating element with a Megger,, The thermostat should be no higher than 170 degs C and if lower, the thermal limiter should still be closed circuit ie. have continuity .. The element should not show any leaksCan I now ask you to rate my assistance.. I will be available for further questions if you need me
