You can unhook it from the rest of the oven and know more buzzers going of anymore,

I have the same oven and the fan doesnt work intermittantly. I turn it on and off a few times and if that doesnt work I give the fan a push with the handle of a wooden spoon. Works so far so I havent bothered with a 'real' fix as yet.

I would say that the oven element has blown. It is common especially if you have a fan forced model. Make sure the fan works before you go buying a new element as the replacement will fail early. Simpson ovens have to be removed from the wall cavity to replace the fan and the element. Make sure you tuen the power off before doing anything...
Give the parts supplier your model number so that you get the fight element ( and fan) if necessary.

I'm presuming that this is a Simpson Nova 65-867
By the look of all the data I can find, this is an Australian appliance. I'm in the UK, and I was presuming that you were in the US, but maybe you're in OZ.

If you are then you can go to

http://www.alliedappliance.com.au/about_allied_appliance.htm

And mail them with a request for help. They advertise loads of spare parts for your oven (but not glass in the listings I have seen). I imagine that they will be able to source what you need.

You can also make enquiries at The Big Warehouse.com, who also stock parts for your oven:

how does the clock work an how do you reset it

In my experience, it is normal to leave the the door open when grilling, otherwise it is liable to cause the bakelite handle of the grilling pan to get very hot, and possibly melt or catch fire, and make it to hot to hold the handle.
Plz rate my solution.

Thanks.
