I have a Kenmore Electric Range (790.9611). The temperature jumps all over the place. We set the temperature for 400F and it will go to 325F one time and 430F the next time. It is not consistently high or low. The thermocouple is not bent and is fully in place in the oven. The range works great. Any suggestions?
ok take the screws out thats holding the sensor in and unclip the connector or the nuts then at room temp which is 72 degrees set your meter to 2000 ohms and you should read 1080 ohms if you dont get that then your sensor is bad
and you can order the part here you can also ohm out the element to if all this checks out then your relays on your board are bad i have to leave for pt back in 1 hr
you have 2 wires going to the element
everything is good but i still dont understand why its fluxuating like this if everythings ok
i would change the oven sensor thats the only part that senses the temp
thats hard to say i never had one do that before set your oven for 350 and put a thermometer in there see how close it gets
I put more money into it than I had hoped, but if I knew a $50 element would do it at this point, it would be worth it to me. It is only a 3 yr old stove so it still looks great. What are the odd that an element would fix it? It seems that it had to be either the thermocouple or the computer since the element is nothing but a wire that heats up when told to.
Ill opt out so another expert can look at it.
I did one test before replacing the heating element. I removed the thermocouple from the oven and set the temp to 350F. After 20 minutes, the oven was heated up to 500F. So, I don't believe the heating element is bad.
What are the chances that the new thermocouple that I installed had the exact same problem as the one in the oven? (Note: the results of the last four times (setpoint/actual): 400/350, 430/320, 350/325, 500/375).
What did the other exxpert say? That test you did just showd that you had runaway heat. Was there a fault code after you did that?
The other expert had me test using another external thermometer to insure I didn't have a faulty external oven thermometer that I was using to base my tests. The other thermometer confirmed the results of the first one.
As far as runaway heat. Please note that I removed the thermocouple and had it hanging at the back of the oven so it was reading 70F the whole time. I just wanted to test that the heating element didn't kick oven out or the computer didn't shut oven off off after it hit around 325F. Since neither one happened I am thinking it has something to do with the input. I could test the thermocouple again using a flame torch on it to see if I can get oven to shut off when the oven is actually at 70F.
With the thermocouple in, it basically only heats to 350F no matter what the target. With the thermocouple out and reading 70F the whole time, it heats to 500F+.
Its got to be the element cause the readings from the control are ok.
I can't believe it is the element. I did a quick test of resistance at different oven temps:
From what I understand, those are reading high and providing a higher than actual oven temperature to the ERC/Clock. Do you agree?
