GE GAS RANGE OVEN PROBLEM

Probably the safety valve. This unit broils and bakes off the same gas burner. A spark ignitor lights the pilot and this save gas because no standing pilot is needed. It takes a few minutes for the thermocouple bimetal combo to release the gas. When the temp gets to the desired rate then the bulb on the oven control closes off the flow of gas. To recap: The flow of gas comes from a regulator along a rail which supplys the gas to the top burners and the oven control. older models had pilot light tubing going down to the oven and to the top burners. This newer style uses a spark module to light off the top burners and the oven. So when yall turn the the oven on the spark ignitor lights the pilot first and then after the mercury bulf thermocouple heats up the bimetal inside the valve opens allowing gas to flow out to the pilot and ignite the gas burner. the temp rises and the mercury bulb oven control expands closing off the flow but not the gas safety valve. I would suspect the safety valve on this one.

does your oven have a pilot light or an ignitor (pilotless)? If it has an ignitor, it probably needs replacing. I can't help you if it does have a pilot light. Do you hear clicking when you turn your burners on, if yes, that means you have an ignitor system.

If you have standing pilots, make sure the pilot for the oven/broiler is lit as well.  When you turn the thermostat up to call for heat, you should see the pilot get larger. That larger pilot flame heats a hydraulic sensor and opens the main burner valve.  

Hello there: The oven bake burner and ignition components are located beneath the oven cavity. In most cases the oven bottom panel can be removed for access (check your owner's manual) but on some models the oven burner has to be accessed from below in the warming or broiler drawer area. If accessing from the top, a 'flame spreader' (flat metal plate) above the burner may also need to be removed to see the burner itself.Many ovens use a single oven burner in which case they only have a single gas valve and ignitor. The same burner is used for both bake and broil functions, the broil usually being in the drawer area below the oven. Higher-end models may have a separate bake and broil burner. On such a system there will be two ignitors, one for each burner. They may also employ a 'dual' gas valve (see illustration above) instead of using a separate valve for each burner.Some range models may have an additional broil burner located at the top of the oven cavity which may be referred to as a 'waist high' broil. If not, broiling usually takes place in the drawer area below the oven, which uses the same bake burner for the broil function. Most gas ranges currently available employ one of 3 basic gas ignition systems; pilot ignition, hot surface ignition system (which uses a 'glow bar' or 'glow coil' - aka an "ignitor") and a spark ignition system. The latter two being referred to as "electronic ignition" systems as they use electricity in one form or another to operate the oven heating system. Only the pilot ignition system has an actual "pilot" (which is a small but real "flame") which might need manual lighting.
If the surface burners of a range are a spark ignition type, the oven IS one of the possible kinds of electronic ignition systems and thus will not usually have a "pilot" which needs lighting. Be aware though that just because the surface burners might light via a spark doesn't necessarily mean the oven uses the spark type ignition system too.
There is one older style of electronic ignition system which does also use an oven pilot but it is very rare and such a system hasn't been used in oven models since the early to mid 70's. It is the 'constant pilot' *electronic ignition* system.


Making Observations
The oven burner's operation will usually need to be directly observed while in operation as the first step to troubleshooting problems.Ignition System Type Links
Ignition System Types:

Pilot Ignition

Electronic Ignition with Constant Pilot (rare)

Electronic Ignition with Glow Ignitor (most common)

Spark Ignition System

Is there continuity between the oven gas valve's terminals?


Hot Surface ('Glow Bar') Ignition System (most common)
This is the most popular system currently used for ovens and is comprised of a control mechanism (whether thermostat or electronic control), the oven ignitor and an oven gas valve.


What happens in this style ignition system is that the thermostat or electronic control switches power to the oven ignitor and gas valve circuit which are connected in series (one after the other). As power flows through the ignitor it heats and draws current (measured in amperage). Once the oven ignitor draws a specific amount of current the oven valve opens to allow gas to flow to the oven burner where the glowing hot ignitor (glow bar) ignites it. Power must continually flow through the ignitor and oven gas valve for gas to be released into the oven burner to create a flame.

It should usually only take in the area of 30-90 seconds for the oven ignitor to reach the proper resistance to allow the proper amperage to reach the gas valve to open it and for the ignitor to ignite the gas at the oven burner.

Your model JGBP28DED2WH uses spark ignition on the stove top burners, and a glow bar ignitor, part number WB2X9154 for the oven and broiler. To get to the bake ignitor if oven will not light: Take the racks out of the oven. Remove oven floor by removing two screws at back of oven floor and lifting floor. Remove the square metal flame spreader to get to the burner / ignitor assembly. (note: The ignitor may still glow when you try it, but usually is still the problem)

Replace the oven glow bar ignitor.

Often times you will have problems with the gas thermostat and not necessarily with the safety valve. Once you have lit the pilot light, turn the oven knob to any temperature. The pilot light should get bigger in size of flame. If not, the thermostat that controls the oven must be replaced. If the pilot light does get bigger, but the stove does not ignite, it is the safety valve.

two options.first does the pilot flame look good (a nice blue flame)?if so you will see a metal probe next to the pilot,use some sandpaper and clean that probe up.if that solves your problem so be it.second if the first thing doesnt work its probably the ignitor board not sensing the flame.the way to definitly tell the one or the other use a small torch and heat up the probe like i said and turn the oven on.if the main burner comes on then you know its the probe which is called a thermocouple and is cheap.hope this helps.

but any chance did you acidentally flip the little lever that will shut the gas off the the oven burner? sometimes its in the back neor near the regulator. check that.

Sister, there is no pilot light on this model. Sounds like you have a bad ignitor, however the F7 code shows as a bad touch pad membrane. d7 must represent how many times this fault occured, although Im not finding anything that shows a d7 code. Try resetting the board by killing power to the range for about a minute. After turning the power back on press the COOKING TIME, DELAY START AND NUMBER 8 PADS ALL TOGETHER. The words test should be displayed. Now you are going to energize the bake circuit; press the bake and start, you should hear a click, this is the bake relay on the board. By holding the start button in you are energizing the ignitor (glow bar) in the oven. If you do not hear the click, suspect the control board. If you do hear the click and the ignitor is not glowing, you have a bad ignitor. Have someone with you to verify the ignitor is glowing when you are holding the start button in. To exit the test, just push CLEAR/OFF key pad. Catriver...post back
