Danny for Model Number Rgb746hed2wh gas oven I'm getting erratic temperatures from the oven. It heats to 300° but the actual temperature in the bake compartment is 150°, I heated it to 525° and it got to 475°. Temperatures are way off. Is this a bad temp sensor, bad ignitor, or just a calibration issue? Keep in mind, it was the correct temperature at one time. I just don't wanna throw parts at it guessing, that starts to get expensive. Thanks, Danny
Answer Hello Danny, This sounds like the temperature sensor WB21X5301 is out of tolerance. You should realize that, without measuring the resistance to ensure a resistance of about 1100O at about 70°F and tapping on it in case of an intermittent connection, this would be throwing a temperature sensor at it. The reason I bring this up is the fact that the control circuit that reads this temperature information sent by the sensor could have the problem. There could also be an issue with the harness that connects the two. As a general rule of thumb, if the sensor tests good and the harness isn't pinched too tightly in a wire tie, the control WB27K10140 is usually the component at fault. Read More...
