Oven Temperature Sensors Help

Oven temp sensors sense the temperature is the oven cavity and the temp sensor changes resistance, this change in ohm resistance tells the oven control what temperature the oven cavity at and tells the control to shut off the element or turn it back on. The most common temp sensors used today ( *not all ) are approx 1000-1100 ohm resistance at room temperature ( 70 degrees F )

Some ohm readings and their temperature:

Degrees F Resistance
100 1143 ohms
200 1350 ohms
300 1553 ohms
350 1654 ohms
400 1753 ohms
500 1949 ohms

Page says "gas oven" but the procedure is exactly the same for an electric or gas oven temp sensor!

*Some different sensor ohm readings at room temp. GE's WB21X158 ( bottom one on the picture ) is approx 16 ohms at room temperature and at 350ºF it is 29~33 ohms.
