Question about GE Profile Spectra JGBP90 Gas Kitchen Range

2 Answers

The broiler glow bar will not ignite so as to produce a flame. What is the problem? I noticed a small piece of the stone (perhaps flint?)coil within the metal casing of the glow is broken off. Will that prohibit ignition? If so, what do I need to purchase to make the broiler come on?

    The oven (bake) glow bar receives enough current to open the gas safety valve because it heats up and produces a flame; therefore, isn't the broiler glow bar automatically receiving enough current as well?

    Thank you so much for your advice. This site is very helpful and I trust your expertise. I will order the part (I have the manual) and try installing it myself, first, before calling for service. Hopefully the part will come with installation instructions. If not, perhaps I can do a search and download them.

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.

    The way the system works is off of resistence. The igniter and gas control valve are wired together. When the igniter first starts to glow it takes all of the 120 volts. Once the igniter reaches 2200 degrees the resistence changes causing about 3 to 4 volts to go to the gas control valve and open to let gas to the burner. The ASO(safety) is built into the control valve so gas is not released if the igniter is not working.

    If the igniter is broken(like in your case) then the voltage will only be on one leg because the circuit is not complete.

    The broiler and oven ignition systems are on two seperate electrical circuits.

Hi


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.


Thanks

Viking oven broiler will not ignite


Your gas valve would be my first guess. Is this broiler (and bake ) lit with a glow coil or spark probe that goes (goes click, click, to light)??
If spark probe, you will have to replace either gas valve or spark board.
If glow bar lights the broil but does not glow, then replace glow coil.

Gas dryer does not heat igniter glows red gas valve clicks but no flame


Hello,

Since the igniter glows i am wondering if within 1 minutes does it go off??or does the igniter just stay on??

If the igniter just stays on and doesnt go off the problem is going to the FLAME SENSOR

if the igniter goes off but no flame the problem will be the GAS VALVE COILS

There is no heat on any of the cycles.


Check Igniter, Igniter Sensor (Senses Igniter is glowing) & gas valve Coils. Remove Front or rear access panel to observe/access these items. Set heated dry cycle & start dryer while observing Igniter, should start to glow bright orange for several seconds, sensor should send millivolt power to valve coils that will CLICK opening valve producing blue flame for heat. If Igniter doesn't glow within a minute, its bad, If it glows & nothing else happens it's either Sensor or Coils are bad, check the coils by using Ohm meter across plug ends of coils, if bad you will get no reading on meter, coil is open & no good, or take both Sensor & Coils to repair shop and have them tested. All 3 are accessable thru access panel opening.

Kenmore Gas Range. Top burners work fine. Oven is slow to preheat. Igniter has a yellow glow and the burner lights within about 20-30 seconds later. However, the burner has a very small flame and it takes...


the ignitor should glow bright orange.it sounds like you have a weak ignitor but if the flame lites within 20 to 30 seconds it sounds like it's ok,it could be braking down though when it gets hot,it doesn't matter if it glows,it has to be putting out 3.2 amps,if you have an amp meter with a clamp on it you can read out the amps,if the broiler works ok i would change out the ignitor,then follow the tube down to the bottom and stick a paper clip in the orifice hole where the gas comes out and make sure that's clear,also there's a shutter on the tube to adjust the air flow,see if it's closed,it's usually almost wide open,check the tube to make sure the ignitor didn't burn a hole through it.i've found tubes with holes in them from a lazy ignitor,most of the time if there's a problem it will be the ignitor

What to do when dryer runs but does not heat up


Things that could stop a gas dryer from heating:
- glow bar igniter, thermal fuse , coils on the gas valve, gas valve, thermostats, motor heat switch, timer, selector switch, sensor.
Problem -
Gas flame comes on first few times then quits and igniter keeps cycling on and off but never lets the gas go.
Answer ( most common ) -
Replace the coils on the Gas Valve.

Problem -
No flame, no igniter glowing at all,
Answer ( most common ) -
Inspect igniter for small burnt spot on dark gray or black part of igniter or check for 110 volts to igniter when dryer should be calling for heat.

Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

Oven takes 5 minutes to come on (ignite).


Replaced the igniter. The parts guy told me that the amperage changes with age and use; thus the igniter still glows, but it takes much longer to operate the gas valve with the reduced amperage. Cost - $70.14

Broiler won't light


Usually, when an oven won't broil, it's because the broil igniter is weak or burned out. The igniter is a small, round or rectangular device, 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 the igniter or the safety valve. Usually the igniter is to blame.

Gas Oven - no flame at Bake Baffle - Glow Bar glows fine


If the glow bar is working (glowing) it is the gas valve. BUT, the glow bar can also actually glow and still not be working 100% and letting enough current through to the valve. You could swap an identical valve out to check it, if you don't have a meter. It's more than likely the valve though.

This will be why the oven acts up. The broiler doesn't rely as much on this as the bake part does. Replace this and it should fix your problem.
