Kenmore 629.46795 Won't heat up after self-clean

10 posts in this topic

Hi there - our Kenmore electric range will not heat up after my wife did the self-cleaning FXN on our range. The cooling fan just runs (like it is still trying to cool the oven down) even after I unplugged it for 3 days. There are no error codes and the light, clock and burners work fine.

It seems that some type of sensor or thermastat was burned up or a reset botton needs to be pushed?

Any advice or direction would be greatly appreciated!

PS- My wife thinks that the self-cleaning mode was stopped (cleared) early by one of the kid, but the door was left locked.

Could not view the wire diagram on the sears site.....Will the oven control respond the the bake prompt??? As in, if you push the bake button will it ask for oven temp??? Or no response ??? There is a thermostat located on the top of the oven behind the console....( Do not know if this controls one leg of the elements, could be temp t-stat for fan operation, But I doubt it ) .......Look for your tech sheet some where in the drawer area.....Pull the drawer if needed............ If not there, look at the rear of the range, If not there, keep looking........post a copy if found.....

Could not view the wire diagram on the sears site.....

Just a quick tip, on the page that shows the previews of all the diagrams, if you Right Click on the wire diagram one and select "View Image" it will bring up the full size diagram.

if the Door is still locked, and the Fan is ON,

the Oven Sensor may be bad

OR the Controller

Thanks Anytime Nick....It is just on this model number that if you click on the wire diagram ( for me anyway ) , It says no parts available.....I use the "view image " to print purdy pictures :sillytongue: ............After looking at the wire diagram that RegUS posted, it probably will be the items he mentioned.... Running Wolfman, you will need to do some testing with a D.M.M. to verify voltage output at the bake/broil terminals , at the board or at the rear of the unit at the elements.....................To test to see if the sensor has failed...,( if you had one,) while the range is pulled out, disconnect the sensor harness ,,two wires (most of the time violet in color) , and just plug in the new one.. ( somewhere I read, some one tried a 1100 OHM resister and I think it worked )........With a failed oven sensor, with the oven still locked and the fan ON, the controller still thinks it is over 550 degrees ( F. ) inside the oven.......Doing a resistance check sometimes will indicate a good reading at room temps. but fails as the temp. increases.....

Thank you ALL for your information. The oven is NOT locked anymore (I have been able to open the oven door) but when it is plugged in the cooling fan just runs and the oven will not heat when I push BAKE. I am able to push BAKE and adjust the baking temp but the oven will not heat, it just beeps signaling that it thinks it is at the set temp.

The Broiler DOES work on both HI and LOW.

The wiring diagram above is the same one I found in the drawer.

Also found in the TECH sheets that it says that during the self-clean FXN the broiler element is on until the oven reaches 790 F and that the bake element then comes on to reach the temp of 875 F and then cycles to maintain the self-clean until it is complete. To me it seems as if the bake element has failed? Please advise me on your thoughts and how I can replace this! Part # 74003039 Will the cooling fan then shut off?...

Check that high limit switch, see it in the wiring diagram.

That Hi-limit opens L1 to the board, If open, no power to the light, bake or broil........Did you verify that the element has failed??? Did you check for power out of the relay.... BA... terminal ???...Did you check the resistance of the oven sensor??? The cooling fan's operation to cool the OCU......... Close the door and push the clean button, after the door lock light comes on, let it stay in clean for about 3 minutes, than push cancel....did it unlock the door , door lock light turn off, fan stop ???? At the most worst case, , the cooling fan relay is stuck closed, the element has failed and the lock assy has failed , but I digress....... Parts changing monkeys are a dime a dozen, you are not one of the dozen , ( are you )...... :dontknowaboutyou:

“My Rules”:

Rule #1) Don't ever use Self-Clean on any Oven.

Rule #2) If you're thinking about using Self-Clean, see rule #1.

Self-Clean uses nearly 1000F for 3 hours or more. burnin.gif

That can wreak havoc on Electronic Controllers and Connections.
