GE Model JKP12G0P2BG Wall Oven Bake Element Not Working Properly

Most double wall ovens are technically two separate oven boxes. The lower oven box has its bake, boil elements, high limit thermostat and ofcourse its own oven sensor. If the lower oven box boil is working good and less heat on bake feature may suggest that the bake element is burned out and only getting preheated with boil element. Just a suggestion here

Ovens often use broiler element to preheat, then shut off when set temp is reached. Check fuses for and bake element itself.

The bake element
is the heating element that is found at the bottom of the oven. Most electric ovens use both the bake element and the broil element in a bake cycle, with the bake element performing 90% of the heating. If the bake element isn't working, the oven may not heat. To help determine if the bake element is defective you should first do a visual check. If the element is blistered or separated then it should be replaced. If the element appears to look normal, then turn the oven on to a bake function for a minute and then turn it off.

Check the element for signs of heating and if it is still cold then it may be defective. Disconnect the power and then remove the back panel. First check the wires as they may have become loose or corroded. If the element appears to be fine visually, test it for continuity with a multi-meter. If the element is burned or no longer has continuity, it will need to be replaced.

Manufacture and model would be nice ohm out the bake element might be open some are in the oven cavity others are hidden below the lower oven plate and have to check from the rear by removing back cover in the bake mode the broil element element cycles on/off thats why you have some heat.

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

Hello there and than you for choosing Fixya
If your oven does not heat, does not heat enough or does not broil, a common cause is a burned out heating element. There are two elements, the baking element on the floor of the oven and the broiling element on the ceiling of the oven. They are about the diameter of a pencil and typically supported by metal stand-offs.
This easiest test you can do is to turn on the oven and observe the heating element. If it glows red, the element is working. When baking, the broiling element may come on to assist with preheating or to maintain the oven temperature. When set to bake, if the broiler comes on, but the baking element does not, the likely cause is a burned out baking element.
When set to broil, the broil element should glow red, but the bake element typically is not used. If the broiler does not glow, it is likely a burned out heating element.
There are other possible causes of these symptoms, refer to our diagnostic page for some other possibilities.
To test the heating element using a multimeter, follow the steps provided below.

1. Unplug the oven or turn off the power at the breaker or fuse box.
   
2. Follow the heating element back to where it goes through the wall of the oven. Remove the bracket that secures the element in place.
   
3. Unscrew or unfasten any stand-off supports that secure the element to the oven.
   
4. Pull the element part way out to expose the oven's wiring connected the element.
   
5. Label the wires and secure them in place so they do not fall back into the cavity.
   
6. Disconnect the wires from the element.
   
7. Using a multimeter set to x1, touch one probe to each of the element contacts. Expect resistance in the range of 20 to 40 ohms. Infinite or kilo-ohm resistance usually indicates a bad element and it should be replaced.
   
8. If the element tests okay, reconnect the wires, slip them back into the cavity and resecure the element.

does the bake element come on at all?
if so, try the oven out. do a bake @ 350 allow it to pre-heat, and see if once the pre-heat is comlete, id the broil shuts off.
on many ovens at the beginning of the cycle during pre-heat both bake and broil elements are powered.

other than that it may be a control board, or a burnt and crossed wire in the harness.

NO HEAT ON BROIL OR BAKE ELEMENTS

CKD WIRING FROM PANEL OK
CKD TERMINALS AT ELEMENT HAVE 120V ON EACH ELMT
FAN COMES ON
THE ON INDICATOR SHOWS WHEN TMP &START PUSHED
MICROWAVE WORKS FINE
I ORDERED A NEW BAKE ELEMENT TO TRY-NOT HERE YET
STUMPED

Trying to better define the problem....

Do you have any cuts, holes or "shorting" or tin-foil/aluminum around your bottom bake heat-element? If so, you may need to replace the baking Heat Element. (Ensure you do not use aluminum foil around your heat element to prevent your oven from getting dirty)

To replace your baking heat element, with power off; remove 2 screws securing the bake element. Slightly tug and pull towards you for about 3 inches or so and disconnect the connecting wires at each end. Then completely remove the heat element and install new in reverse manner. Whats' you're model number?
