Convection oven quit working half way through cooking thanksgiving stuffing

The fan is likely for convection cooking. And it sounds like you might be used to cooking on convection mode. Try changing it.

f the oven doesn't heat and the on-off light works, test the appliance controls, motor,
and heating element .

A lot of ovens have a convection option, and the fan will only work in this position. Otherwise, just rotate your pan halfway through, like we always did.

If it's getting hot, but it isn't cooking as fast as normal, your convection blower/fan may be out. If you can hear the fan running, but the oven isn't getting hot enough, then you most likely have a heat element or thermostat problem.
Fan and blower problems tend to be a bit more common with convection ovens.

The problem is usually down to the thermostat - sometimes it can be moved and end up touching the grill and burning out - other than that they just wear out after time with the heat.

Have a look here for a spare - its easy to replace if your husband is half competent with fixing things.http://www.espares.co.uk

The fan runs to circulate the heat inside the oven for more even and faster cooking...That is how a convection oven works :)

I repair commercial cooking equipment for a living. When a customer complains about uneven cooking the #1 thing that these manufacturers ask is..... are they turning (180*) the baking sheets half way thru the cook cycle. #2 are they staggering the pans front to back & side to side. It's kind of a pain but, works for the commercial ones.

Turn your breaker off and back on. If you only have half voltage everything but the elemnets can come on.

Im going for my reset switch...its on the top - outside the oven - behind the panel...

I am by no means an expert, but I believe the only thing differenty in a convection oven vs a regular oven is that there is a fan to conduct the heat quicker and more evenly. It has to do with heat tranfer rate. I can't imagine why aluminum foil would cause any problem.
