Question about GE Profile Spectra JGBP90 Gas Kitchen Range

GE Spectra Range

I'm using natural gas. It was working fine but now the high speed burner is sooting the burner and the pots and pans occasionally. the flame is nice and blue and when it fails it seems to be uneven and orange. I removed the burner, cleaned and checked the jet and it all looks like new. None of the other burners are causing a problem and the oven is working fine. The fact that it is intermittent has got me baffled. Could the valve cause this problem, I don't know what is left.

Re: GE Spectra Range

If you have a pressure regulator coming off the main gas line to the unit make sure the vent isnt clogged.its a little nut on top of the regulator,unsrew it and clean it up with w-40.try this and see what happens.if no improvment the gas valve is faulty.

Re: GE Spectra Range

There is too much air in the mixture, close the air shutter on the burner a little.

How tp clean black soot off bottom of turkey pot

If you are cooking with propane or natural gas, you may need a new regulator for your range, the black soot is most likely too much gas being used to make the flame. But, as for the soot on the bottom of your pans, try letting the pan soak in a mixture of baking soda and water, then attack it with a brillo pad. Hope this helps!

Air mix of burners is wrong. Need more air vs fuel.

Should probably get a pro to adjust under warranty.

Gas stove causing soot on everything

all of the burners are set to the vents on the burners more.  If this doesn't help you need smaller nozzles.

Flames are extremely uneven and high


It's not intended to be used with LP gas, because LP gas requires a smaller orifice than natural gas. Call your propane supplier IMMEDIATELY...DO NOT USE THIS STOVE UNTIL IT IS CONVERTED TO LP GAS (if it's even possible)...this is extremely dangerous and you could hurt yourself if you continue to use LP gas on a stove that was designed to run on natural gas.

Black soot on bottoms of pans

Wellif you uninstalled and reinstalled the same appliance it should work the same.. thats weird that it changed. however the black soot is usually from flames that are to high. you could try tightening down the orifice where the gas comes out.

GE Profile Spectra Kitchen Range

Are you using natural gas or propane (LP)? It sounds like you may need to change the orifice size on the gas lines going to each burner. If you are using LP and have the orifice set for Natural gas, the flames will burn higher and hotter, causing heavy soot. Under each burner, there should be a small nut with a hole in the center at the end of the gas line. The hole for Natural gas has a slightly larger diameter than one for LP. Your stove should have come with extra orifices as part of a conversion kit. Could this be the case? There's also another orifice in the main gas regulator in the back of the stove. Have you checked to see if the orifice for the regulator is set correctly? Does the oven burn hotter than usual with heavy soot, too? If you could please answer these questions first, I can give you better advice. Let me know...

Black soot on pans

You could be correct in your assumptions. There should be a set of small brass nozzles included wirh your installation instructions. these are for the burners and will have to be changed. There is also a gas regulator that attaches between the gas line and your range, there should be a large brass hut on one side. the nut is removed and a peg on the underside has to be flipped over to convert the regulator to LP. There should be instructions included in your installation manual or contact GE for the parts and instructions if you do not have them.
