Question about GE Profile Spectra JGBP90 Gas Kitchen Range
The glow bar you are describing is called a "hot surface igniter". It uses electrical resistance to create enough heat to ignite the burner. If the igniter coil is cracked or broken off as you describe this will cause it to not work. In that case you will need to purchase a new hot surface igniter to repair the broiler. They usually cost around $60 dollars and are not supper difficult to install. You could remove the igniter and bring it to your local appliance parts store and have them match it up or order on online using the model number and serial number for the range. Let me know if you have any questions.

Thanks for using FixYa. Please check the current/amp drawn by the igniter and see this repair sheet to check whether it is fine or not. The gas valve has a bi-metal that open when a certain amount of current flows through it to heat it up. The igniter is wired in series with the gas valve. As the igniter gets older or weaker, its resistance increases to the point where not enough current is flowing to the gas valve bimetal to open it up. As a result, the gas valve never opens up. BTW, a common symptom of the early stages of this problem is erratic temperature control in the oven due to delayed firing of the bake burner while cooking.
The hot surface igniter will not come on - check igniter with an ohm meter, you should have continuity through the glow bar, the glow bar can also crack = new igniter time. The glow bar comes on but the main burner will not light - you should have an amp probe to check properly, but often this is a hot surface igniter problem. The hot surface igniter often looses its ability to get hot enough to open the gas safety valve. The safety valve can fail, but most times it is just a bad hot surface igniter. The hot surface igniter can also quit part way through cooking, in other words the oven may cycle a couple of times and then it just sits there with the red glow from the igniter. See this service sheet for the proper way and amp readings for the hot surface igniter system. Hot surface igniters do weaken and will eventually generate less heat than they normally could. When this happens they can still allow marginally correct current to flow to the oven gas valve for it to open but not get quite hot enough to ignite the gas burner immediately. When this happens, gas released into the oven can sometimes build up to the point where when finally ignited, the amount of gas lit can cause a small explosion inside the oven or cause an odor of gas with out the oven working.
Please do accept the solution if the issue is resolved or else revert for further assistance.
