I have a GE JGSP33 Slide-in Gas Range. The oven?s Bake burner has problems lighting. The igniter comes on and glows, but it seems the gas valve doesn?t open, even after 3 minutes. I can generally get the oven gas valve to open (and the oven to light) by lighting one of the stove-top burners, which seems awful strange. The stove-top burners and broiler work fine. It seemed this behavior started when the gas company shutoff our street?s gas line for half a day, but that could be coincidence. Is this a bad igniter, debris in the gas line, or something else entirely?

pull out the racks and remove the bottom floor of the oven,turn it on bake,if the ignitor doesn't glow most likely it's bad,if it does glow and it doesn't ignite within 40 to 60 seconds the ignitor is bad.even though it glows doesn't mean it's good,it works by amps.it takes 3.2 amps.for a flat ignitor to open the gas valve and 2.5 amps for a round ignitor to open the gas 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.

When the bake igniter becomes weak or burns out, your oven will not bake. The bake igniter is usually mounted on the oven burner. It's about 1 inch by 4-8 inches (depending on the model), and comes in round or flat styles. If you don't see the igniter glow at all, it's probably burned out. Replace the igniter if found defective. Note: one of the exceptions could be that your oven is set to automatic mode instead of manual. If this is the case, set your oven to manual mode and check again.

If the bake igniter glows red and not bright yellow or white, it is probably because it is too weak. When this happens, the safety valve would not let the gas out into the oven burner. A weak igniter must be replaced.

A faulty igniter is probably the most common cause, however there are others:

-- defective thermostat
-- defective selector switch
-- defective gas safety valve
-- defective gas valve coils

Bake igniter
Other causes
Bake igniter Usually when an oven won't bake, it's because the bake igniter is weak or burned out. The igniter is a small, round or rectangular device, that's about 1 inch by 4 to 8 inches. It's near the burner itself.

The burner is the tube-type device the gas flows through before it's ignited. It has many small holes on the sides to let the gas, when ignited, form a long, low flame. If the igniter is weak, if it glows red but doesn't get hot enough, or if it's burned out, the gas doesn't flow to the burner and the burner won't ignite. If this is the problem, you may need to replace either the igniter or the gas safety valve. Usually the igniter is to blame.

Other causes Other reasons that your oven may not bake are:

• The clock settings are incorrect (if you have timed baking or a self-cleaning oven).
  
  
• The thermostat is defective.
  
  
• The safety valve that prevents accidental gas flow is defective.
  
  
• The selector switch is defective.
  

You probably have a bad gas valve, part # WB21T10014, unless the new igniter is defective. If your broil works, you can prove this by temporarily hooking the broil igniter in the bake spot. Hope this helps!

jdelvecchio5Does the igniter (glow bar) come on whenever the bake function is selected.?

If the glow bar does not come on the safety valve will not open - no bake burner. check the electrical harness first then Try changing the igniter (glow bar first) before changing the safety valve/regulator.
