We just purchased a GE Spectra gas range used. I believe it was set up for natural gas and we have LP. I think this is causing an improper air fuel mix. Could this be my problem and if so how do I make the proper adjustments. Thank you for any help.

Re: 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.

Normally soot is from a range that hasn't been converted for the gas type, like natural or propane. It may be set up for natural when you're on propane or visa versa. Has this range ever worked properly without sooting?
the burner orfices will have to be changed ans pressure reg / some have either /or reg / just turn lever to the fuel you are using . but always change the orfices to gas or lp . blk is lp copper nat gas .. you can probably do it with out the instructions it's very simple .. if the other set of orfice's are not in or on range then order them for your model . ..mm
GE ships gas ranges set for natural gas, with the LP orifices included, usually on a metal tab held with one screw right near the regulator (where the gas connects to the range). If the range was converted to LP, the person who did the conversion was suppose to put the natural gas orifices back in that holder. If they are missing, comment back on the exact model number and I can look up the part number(s) for you.
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.
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.
well its my experience that ranges don't come lpg they are all made natural gas but you convert them to lpg after purchase now if the lpg conversion isn't done properly then they soot like crazy proper lpg converson is to change the spuds on the burners and to turn the orifice over in the pressure regulator do you still have your owners manuel if so consult it on converting gas range to lp then check to see if every thing was done right on the pressure regulater there is a square cap you take it off and there is a round part that on one side says lp on the other says ng this changes the pressure that the regulator as ng and lp operates at different pressures and the regulator has to be set for what you using like i said im not familiar with your brand or model but i do know the problem if the range did come ng then you need to make sure the conversion most ranges aren't lp because there is not that big a market for it read the plate on the back will tell you if it was made ng or lp serial plate on front may say also most of the time it is beside the bottom drawer on the 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...
