I have an ancient Sharp R-8310 microwave/convection oven that recently
broke its temperature sensing thermistor for the convection part. I'd
like to keep this oven because of its simple mechanical controls, but
what kind of substitute thermistor will work (temperature @ 25C,
temperature coefficient)? The factory part (FH-Z0017WRK0) is $40 with
the thermistor in a plastic shell and attached to a cable.
