Sharp microwave/convection oven thermistor

$40 sounds pretty decent to me, it's surprising the part is still available at all. If it were me I'd just buy the factory part and save the substitution for impossible to find or horrendously expensive parts.

I just had to replace that part and it cost $40 in Australia. I also like the Sharp. IMHO, it's well worth it to fix it.

Of course, there are a variety of standard thermistors that go for more along the lines of $1 from an electronics distributor.

Does anyone know what the specs on this are?

Is it not in some special housing? I was envisioning a probe for sticking into meat, perhaps this is just a cavity temperature sensor.

It is the cavity temperature sensor and looks like a common glass diode, but it's housed in a small plastic shell with spade lugs on it.

I'm not sure about that model, but the one I replaced a few years ago was just soldered (or maybe spot welded) between two posts out in the open.
