Question about Kenmore Ovens

1 Answer

It seems my plain fan convection oven takes significantly longer to pre-heat to 350 degrees when in convection bake.

My new Kenmore Electric plain fan Convection oven seems to take significantly more time to pre-heat the oven when it is set to convection bake. BUT IT WILL GET TO THE PRE-HEAT TEMP. At least it takes much longer than my old standard oven did. Is the convection bake setting known to take longer to pre-heat? ___2. if that is true is it quicker to pre-heat in standard mode and then switch to convection bake?

I would check the oven sensor it may be defective

Oven comes on and off intermittently or heats very little:

If the timer feature is activating and you have not touched the timer button at all, this would have to be a failed Electronic Oven Control. The timer button is either shorting at times or closing on its own from heat or moisture. The Electronic Oven Control would need to be replaced to repair the problem.

Or Why does it take the oven so long to bake?
When the food is taking way too long to bake, it's probably a weak bake ignitor. Replacing the ignitor usually fixes this problem, but you probably want to verify that the ignitor is the problem before replacing it.

Sometimes the oven thermostat or oven sensor can be calibrated wrong, or it may be faulty. If your particular range has an oven that uses an electronic thermostat, and the oven temperature is off by tens of degrees, you probably have to replace it.
On most units that have a mechanical thermostat, you can actually remove the thermostat knob, and adjust the knob to more accurately represent the actual setting of the thermostat. On many models, there's a screw on the back of the knob with a small calibration plate or ring. You can loosen this screw and adjust the calibration plate. Remember to tighten the screw again. If yours isn't adjustable, and the temperature is off by a large amount, you should just replace the thermostat.

Or Oven safety valve needs to be checked with multi meter ohms / voltage

ALSO Test the Burner Heating Element The stove's burner heating element is a coil of metal sheathed in an insulator. Electrical current travels through the element. Resistance to the passing of electrical current causes the element to heat up. A precise temperature cannot be set for a burner, instead it is turned on and off repeatedly by the control to the achieve an average temperature. When it is set to a low temperature, the element is cycled on and off more frequently. For high temperatures, the heating element is energized longer with fewer on and off cycles. Some burners have two elements, with the second only being used only for high heat settings.
Before testing the heating element, unplug the appliance or shut off the power at thefuseboxorbreaker panelto avoid an electrical shock hazard.
When a burner does not heat at all, or only heats up to a lower than expected temperature, the problem is likely to be with the heating element, the temperature control switch, or the wiring. If it only heats at the highest temperature, the problem is with the control or an electrical short, not the burner. If the burner works only intermittently, the problem is likely in the wiring or connectors. To test the heating element, try the following steps.
First, disconnect the heating element from the stovetop. In most cases, this is done by lifting up the burner on the side opposite of the terminals (the part of the burner that disappears under the stovetop). Remove the decorative ring.
Inspect the style of connection. If the burner element has visible blades that fit into the receptacle block, pinch the block with one hand, and pull the heating element free with your other hand. If the terminal block clamps over the element, the housing must be removed and the burner wires disconnected. Unsnap the metal piece or remove the screw that secures the receptacle block and then disconnect the element.
Inspect the heating element. If you find bubbles, warping, or damage to the insulation sheath, the burner must be replaced. If the terminals are dirty or corroded, this can cause poor temperature control, intermittent problems or complete failure to heat. Clean the terminals with steel wool or very fine sand paper to restore good conductivity.
Test theresistanceof the heating element using amulti meter. Set the multi meter to the ohms setting X1 and touch one probe to each of the terminals. A normal reading is typically somewhere between 20 and 120 ohms. The exact reading differs by manufacturer and mode. If the meter reads infinite resistance or the other extreme of the scale, zero resistance, then the element is damaged and should be replaced. If the measured resistance differs significantly from the expected range, the element is probably bad, but if possible, determine from the manufacturer what the actual resistance should be.
To test for a grounded or shorted element, touch one probe to the surface of the burner and the other probe to each terminal in turn. If you get continuity at any time, the heating element is defective and should be replaced.

Dacro Wall oven (electric) does not heat past 345 degrees on bake or convection bake but broiler works and bottom oven works fine (for bake, convection bake and broil).


it could be the oven temp sensor rod located near the top of the inside of the oven,or possibly the bake element has a hot spot on the element and can no longer pass enough current thru this spot to correctly heat to your settings a hot spot on the element will look discolored in this area

My Kenmore Elite oven will take over an hour to preheat to 350 degrees and never does get done preheating.


There's a few things that can cause this.

1. Check to see if the both that Bake and Broil elements (burners) are heating up. Check the Broil element in Broil mode.

- during pre-heat the Broil element gets cycled on and off for short time durations to speed up the heating. If the Bake element is not working, then the oven will heat, but very slowly and never reach high temperature.

2. If the elements are both working, then it's possible that you have a bad temperature sensor.

- this is a temperature dependent resistance device that should measure 1080 ohms at 70 deg F (room temp).

3. If #1 and #2 are ok, then the problem is with your oven clock/control unit. We rebuild these at fixyourboard.com.

The oven temperature isn't correct. Ovenw Won't heat up.


has the oven got a fan on it. if so then maybe fan is faulty.
if convection oven then maybe one of elements is faulty
or the thermostat is a problem

Oven takes 20 minutes to fully heat on bake - Kenmore oven plt095-2


if its a gas model most of the time you will have a weak oven ignitor. if an electric,check to see if the bake element gets hot ,some ovens will bake with upper and lower elements so if only the upper works it will take much longer to pre-heat.good luck!

I have a Bosch HBN 455 double oven with the convection oven on top, and a regular oven on bottom. The unit is about 5 yrs old. We recently ran the Self Clean mode, and it seems like it has malfunctioned...


Hi,

Do you see any Error Message on the Display?

If not, then it should not be a Concern. More often this could be Thermal Fuse on the Back of the Unit ( On Most Models ) will stop the Broil and Bake from Turning ON. You would just start a bake cycle and the temperature will sit at 100 and something degrees and never raise.appliance.

Let me know, once you check the same.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

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.

Baking with digital oven


First let me address the temp ... Buy a meat thermometer and test it against the temp set in the oven.  Though that isn't the most accurate, it should prove whether or not it is way way off.
Second.. convection baking takes considerably less time.... 
Third... elevation plays a key factor on baking but not so much on cooking meat.  Baking above 2500ft elevation takes 20% longer and above.

Amana Convection oven not controlling temp


I have just checked the baking guide in the manual and have found that it may not be us after all. (Maybe this is why they telll us to read the whole manual. Well, I never have) According to the cooking time for Baking, the range is very extensive. For example, an angel cake at 350 could take from 28-50 minutes, buscuits at 375-400 could take 8-16 minutes, layer cakes at 350-375 could take 25-40 minutes, pound cakes at 325-350 could take 45-70 minutes and fresh pies at 400-450 could take 35-60 minutes. Basically, the baking directions on the box means absolutely nothing to use Amana oven owners. We have no choice but to cook our food or baked goods until they are cooked, whenever that may be. :) Linda
