Degrees C=(degreesF - 32)*5/9

212F =100C
220F =104C

This forum is hardly devoid of college chemistry students.

the problem is that both of the fan is coming on at the same time. there should be a low speed and high. is it the rely that is mess up? is there things that i should check out. i just don't want to keep changing parts if i am not shore it will fix the problem.

i don't understand why we have a high speed and low speed.shouldn't the low speed go on first and if the temp doesn't drop the high speed will kick on.

Both fans run when the temperature is between 212 and 226 degrees. Then, one of the fans has two speeds, that one speeds up when the temperature reaches 226 degrees.
