The Corvair thermistor has a 5000 ohm 'base' resistance - meaning that
at room temperature, the resistance is 5000 ohms. With all Thermistors,
resistance drops as the temperature rises. So for instance, at a 400
degrees, the resistance drops to 300 ohms. I've tested several by
getting some High Heat wire from the local hardware store, wiring up the
thermistor with the wires hanging out of the oven, and putting the
thermistor in the oven and measuring the resistance going down as the
temp goes up.
Unfortunately, there is no current "screw in" replacement for this item,
although a few people (including me) have toyed with the idea.
Hope that helps,
How do you test a used thermister and what is the BEST way to remove one form a head. This should stir things up.
Thanks to all that replied to the question about the threads on a thermister.
