WB23X5340 Oven Temperature Sensor

What to know

When an oven won’t hold its setting or heats unevenly, a temperature sensor is one component worth checking. The WB23X5340 is a replacement oven sensor intended for certain GE ranges and stoves.

Its job is to provide temperature readings to the oven so the appliance can regulate heat. The listing connects this part number with replacements including AP2023913, WB23T10002, 253024, AH236490, EA236490, PS236490, and WB20K5035. It also names a range of GE model families, including JKP and JSP models. Those references can help narrow down a match, but they are not a guarantee for every oven.

Keep in mind that a sensor is a targeted replacement, not a fix for every heating problem. A failed control, wiring issue, or another component could produce similar symptoms, so don’t assume the sensor is the cause based on temperature behavior alone.

How to use it

This part is meant to replace an oven temperature sensor, rather than serve as a separate thermometer or cooking accessory. If your oven struggles to reach its set temperature, fluctuates, overheats, heats unevenly, or does not heat, compare the appliance’s model information and existing part number with the compatibility details before choosing it.

A practical scenario: if a recipe calls for a steady oven setting but the appliance repeatedly seems too cool or too hot, the sensor may be one item to investigate. The symptoms listed for this part can also have other causes. If you’re not experienced with appliance repairs, use the oven’s service instructions or consult a qualified repair professional instead of guessing at the fault.

Practical tips

Start with the full model number from your range or oven—not just the brand—and check it against the manufacturer or parts documentation. The listing gives examples such as JKP15, JKP27, JKP45, JKP67, JKP70, JKP75, and several JSP models, but it does not establish compatibility with every GE appliance. Confirm the exact replacement number as well, similar-looking parts are not necessarily interchangeable.

From the way it is set up, this is a focused option for a sensor-related repair, not a broad solution for an oven that has stopped working. Before replacing anything, consider whether the symptoms point to a different fault. Follow the appliance’s repair guidance and disconnect power as directed before working on it. It suits you if you have confirmed that WB23X5340 or a listed alternate part number matches your appliance. Not the best choice if you need a complete repair kit or have not verified the model fit.

Before you decide

Which problems is this sensor listed for? The listing mentions failure to reach the set temperature, unstable temperature, overheating, uneven heating, failure to start, and lack of heating. These symptoms do not confirm that the sensor is faulty.

Does it fit every GE range? No universal fit is stated. Specific JKP and JSP models are named, so check your exact appliance model before ordering.

Is this a complete oven repair? No. It is a replacement temperature sensor, other causes of an oven problem may require a different part or repair.

When it makes sense

Choose this part when your appliance’s model and existing part reference line up with WB23X5340 or one of the listed alternatives, and the repair you’re considering is specifically for the temperature sensor. That’s a more targeted approach than replacing a larger assembly without identifying the fault. If the model match is uncertain, or the oven’s symptoms could point to controls, wiring, or another component, diagnose the issue first rather than treating this sensor as a guaranteed fix.
