Thermo-STUCK

After taking all three thermostats, recording what i thought the opening temps were and submerging in water i realized that #2 was open and i wast sure when that had happened. At that point I took all three thermostats out of the water and submerged them in cold to see if i could get #2 to close again. I had no luck their, thermostat number 2 was stuck open.

This is the info i came up with for thermostat 1 and 3.

#1
Estimated open temp: 95 degrees C

Actual open temp: 90 degrees C
                             195 degrees F

#2
Estimated Open temp: 180 degrees C

Actual Open Temp: 85 degrees C
                              185 degrees F

I found that attention to detail is important! i didnt pay close enough attention to notice the thermostat that had opened and it had stuck. I also estimated the wrong degree for thermostat #2. Even though the number read on the thermostat did have a C by it, it was not signifying Celsius.
