    It starts heating withion 30 seconds. Would the ignitoe possibly be an issue if this is true or should I order the over sensor. I can but it for around 50 bucks.

    Can the ignitor actaully under perform so it would not reach the temperature desired?? Is it hard to switch the ignitors?? My model number is JGBP798EB588, is there a particular part for this model?

    I have the same problem. I love to bake and cannot bake anything in this oven. I had the repairman come out the first year I owned it and he said it calibrated properly. Unfortunately I believed him. I have been baking at my boyfriend's house, but now want to bake at home and can't with this stove/oven. I just wrote to GE

    Both ignitors work and I switched the Sensor. I think 1 issue might b when the bottom burner ignites the flmae seems somewhat high and normal anf then after a while turns down to a lover flame even before the oven has reached its desired temperature which slows the heating quite a bit. Is there a regulator issue that I might have for how much gas is being determined to use?I

The oven sensor ( WB21X5301) is suppose to tell the oven control when to turn on and off to reach and maintain oven temp, but before you go replacing it, try to observe how long it takes from the time you turn the oven on to the time the oven ignites. Ignition should be 30 seconds to about 90 seconds. If it is taking a very long time, replace the igniter (
). Ignitors get weaker over time, and this should be looked at first, as both parts are not real cheap, so you don't want to just start throwing parts at it. Here is a trick you can try: On the JGBP90 (model you posted under) the broil ignitor is the same part number as the oven ignitor, so if the broiler, which is generally used much less than the oven, is working fine you can interchange the two ignitors to see if that solves your oven temp problem without having to buy a oven temp sensor first.

    Sounds like a sensor then, but you can try this if you'd like: The broil ignitor is the same part number (on the JGBP90 you posted under) and the broiler is usually used much less, so you can switch them to see if it makes a difference before you order out a sensor. I'd also be leary of buying parts from non part dealers, as you don't know if their parts are really good or not. Have heard of lots of people buying parts off ebay, etc., and getting bad parts.

    Well, it is important to post under, or at least list the correct model number. The ignitor for a JGBP79BEB5BB is a
    WB13K21 and the sensor is the same

    WB21X5301 as the other model range uses.

    Another thing you should consider is how you are testing the oven temp. When I check the calibration of an oven, I use a digital thermometer with a remote probe which read down to the 1/10 of a degree. I make sure the oven cycles on and back off at least three times, then average the high and low readings after that. (with gas ovens, the difference from high to low is often only about 10 degrees F) Home oven thermometers generally are dial type bi-metal coils which react much slower and are not very accurate. Make sure if you are relying on one of those that you especially don't take a temp reading until at least 3 if not 5 or 6 oven on / off cycles.
    Please consider changing your rating to a fixya if this helps.

    I have not seen a regulator issue on a gas range, other than if one was not converted when Nat to LP gas (or vise versa) was done. At this point a repair person may have to be called to use a manometer to check gas pressures. They will check pressure at the oven burner orifice with at least one top burner on. The range does not have more than one burner setting. It's either on or off. For this issue, you may have the best luck contacting your gas supplier.

JGBP79 GE Spectra XL44

Yes I had the same problem on my JGBBP79. Change the lower igniter. About $75. Keep the range for a few more years and get rid of it. The next problem you'll mostly likely have is the touch pad F1 error. That stupid thing is +$300 and nothing more than a membrane touch pad attached to some glass. :-(

Ge spectra xl44 stove

Most likely the oven ignitor is bad or weak.  You can look at it and see how it compares to the broil ignitor.  If you see a whitish color on the ignitor and if it doesn't fully glow then it needs to be replaced.
