GE Range Model# JBP70WK4WW

[Adirondack Bob]

Hi All, Have a GE Range Model# JBP70WK4WW with an F3 Code. Temp. senser ohms out at 1.592 K Ohms. Try to pre-heat the oven to 350 degrees, within 2-3 minutes it says it is pre-heated, but the temperature in the oven is NOT at 350. Is this most likely the Senser or could the Control be bad? This customer is an hour away, just want to make sure I order the correct part.

Thank You Kindly, Bob

.... Temp. senser ohms out at 1.592 K Ohms.

... within 2-3 minutes it says it is pre-heated, but the temperature in the oven is NOT at 350.

1) Sensor should read 1100 OHMs at room temperature....What temperature does the Oven Display at room temperature ?

2) does the Oven Display read 350 F after pre-heat ?

At room temperature= 1.512 k ohms.

Oven Displays 350 after pre-heat, Pre-heat only lasted about 3 minutes. Temperature in oven is NOT 350 when the pre-heat ends and temp reads 350 on the display.

At room temperature= 1.512 k ohms.

sounds like a bad Thermistor

Oven Display probably read about 280F at room temperature

Thanks Reg, I will bring a Sensor with me. When I push the Bake Button, the Display says PRE. It did not show a temperature on this oven. When it thought it was pre-heated the display changed to 350. I know what you mean, some say 100 for a while until the temp reaches 100 then it starts to climb. I know I saw a chart somewhere that listed the resistances/temperatures of the sensor, but I can't find it now. Thanks, Bob

i did a quick search and it said 1100 OHMs at room temperature and 2 OHMs per degree increase...

1512 - 1100 = 412

412 / 2 = 206 + 77F = 283F

wouldn't take long to get to "350F"

Appreciate the help Reg!! You Rock!

Last time I ran into this problem it was a bad clock, not a bad sensor.
