The infinite switch
on the control panel controls the power to each surface element. If you have no heat at an element and the element and terminal block check ok, then you may have a defective infinite switch. Disconnect power to the range and remove the console back panel. Locate the switch and check for overheated wires or faulty terminals first. Test the switch's contacts for continuity with a multi-meter. If defective, replace the switch.
If the infinite switch does not appear to be defective, then you should check for proper voltage to the switch. This is a live high voltage test and should only be performed by qualified persons.

Most modern ovens use an electronic control board
to control the oven functions. These models will use the control board to operate the oven safety valve on a gas range or oven, and the bake and broil elements on an electric range or oven. If there is no power to the igniter circuit, or the element circuits, then you should check the control board to verify that there is power at the appropriate output relay. These are live voltage checks and should be performed by qualified persons only. If there is no output voltage then the control should be replaced.

The oven safety valve
(also called the gas valve) is the part that ensures that gas is not released until the igniter has reached the correct temperature needed to ignite the gas. While this part can fail, it is uncommon. If the hot surface igniter does not glow you should first verify that you have voltage to the circuit. This is a live voltage check and should be performed by a qualified person. If voltage is lost at the valve terminals then you should verify the continuity of the bi-metal in the valve using a multi-meter.

How do get rid of F10 which is on the window of my Kenmore stove

The F10 error means that the high temperature sensor is reporting a runaway temperature and shut down to avoid a potential fire. Try unplugging the stove or tripping the circuit breaker to reset the code.

If the error recurs, unplug the stove (or turn off the circuit breaker) again. Look at the broiler and bake elements with a flashlight. If it has any damage (breaks, char, melting), you will need to replace the element. Check where the elements connect to the oven and replace them if there is any charring on the back wall.

If the elements are undamaged, you need to check the wiring to identify if the problem is at the elements, the high temperature sensor, wiring or the control board. You will need to access the wiring from the back of the stove. Disconnect the wires to the heating elements. Then disconnect the wiring connections at the high temperature sensor and the control board. Without a model number, I can't be completely sure of the resistance that should be seen at various points. Please post a comment with the model number of the stove and I'll try to confirm the expected and faulty resistance values. Most likely, the resistance should be under 50 ohms but above zero between the left and right contacts of the elements and the violet wires in the wiring harness at the control board. The high temperature sensor should probably have a resistance between 1,000 and 1,200 ohms. If the resistance is high, you'll need to replace the appropriate parts. (Note: if the wiring at the control board gives a reading similar to the resistance of the high temperature sensor, the control board is the likely suspect.)

I hope this helps. If your stove is under warranty, contact Sears/Kenmore to fix the issue. If you aren't comfortable testing the wiring, contact Kenmore for a service call.

Broiler turns to pre heatworks oven doesnt heat when temp

the broil element
is the heating element that is found at the top of the oven and produces a very high heat for broiling. If the broil element isn't working, you should first do a visual inspection for signs that the element has blistered or separated. If the element appears normal then you can check for continuity with a multi-meter. Remove power from the appliance before performing this test. Remove the back panel and locate the terminals for the broil element and inspect the terminals and wires for signs of overheating or damage.

If there is no continuity then the element will need to be replaced. If the wires are damaged then they will need to be repaired. If the element is ok then you will need to check the broil circuit to determine the cause. This involves live voltage checks and should only be performed by qualified persons. Components to check include fuses, if the range is equipped, and oven control thermostat or electronic control.

Temperature in Kenmore double oven will not reach

Hi,
The baking element is probably the problem...

My oven is burning my baked goods, but shows the right temp with a thermometer. Do I have to turn the dial to broil and then back to the desired temp? Even if the rack is in the middle, everything burns....

If it is convection bake you have to turn the temp down (25 degrees or so) that is listed in the recipe.

The broil setting is not used to bake because it operates differently from the bake setting. So, don't go to the broil setting at all.
The element for bake is under the floor of the oven. You have not indicated whether it is gas or electric, but both of these can have issues with the burner or element.

If you are baking on the correct setting and the oven is heating from the bottom, not the top, this can be caused by hot spots that are created by elements/burners.

to check, look under the floor of the oven. Turn the bake heat up to high and see if the flame is uneven. For an electric oven, the color of the element should be evenly red, no brown spots.

If you are using an oven thermometer, move the thermometer to the spot in the oven that seems to be burning things the most.

My question concerns a Kenmore glasstop electric oven (model #790.95200100). While operating the oven at 450 degrees and the back right burner at level 5, I heard an audible "pop" and saw a flash of light...

After letting the stove cool, I pulled the entire unit out from the wall and discovered scorch marks on the wall. Opening the back panel revealed a simple fix: the "element on" light module had shorted and was visibly scorched and melted. Looks like a simple replacement (and some wire stripping where the leads fused). Stove currently works with the affected wires capped off (while I await a replacement module).

Oven not working

you would have to check the element for continuity. Also the oven sensor could be suspect and should ohm out at 1180 at room temp. if both those are ok then main control is probable. without schematic it would be hard to say for sure..there may even be a safety fuse blown.

Lower oven does not work. Ind. light comes on but no heat

It sounds like your heater element is burnt out. Get a volt meter.unplug the stove.take off the back,disconnet one of the wires connected to the element and test it. It should read aproximately 11 ohms if good. if a high or no readind,the element needs replacing.

Kenmore Range 911.9324890

Replace recepticles for large elements. It is the part that the heating elements go into. And while you are at the appliance store, pickup a new bake element for your oven. Just unscrew element from oven wall and install new one.
