Can I substitute GE cooktop knob WB3K5264, WB3K5281 or WB3K5296 for WB3X5245?
Answer Hello Don. No, the knob you are needing does not cross over. The part has been permanently discontinued by the manufacturer and we don't know of any source or replacement for the part.
Does this model have a stem that is about 1 1/2 inches?
Answer Hello Lana! Unfortunately, we do not have the specs available on the knob WB3K5296 to verify the stem length. If you would like to repost another question with your appliance model number we will be glad to verify if this is the correct knob. Thanks.
