When i increase the temperature control the oven soots excessive

The oven flame needs to be adjusted so more air will mix with the gas. This is unsafe since the amount of carbon monoxide is greater under the circumstances.

Faulty range/oven parts aren't the only worry a gas range owner has; the threat of carbon monoxide is very real and should be paid close attention to when doing repairs on the range.

If your range or oven gives off soot, you definitely have a carbon monoxide problem. Soot is the result of inefficient or incomplete combustion. There are always elevated levels of carbon monoxide with soot production. Properly adjusted range/oven parts do not give off soot. You may have poorly adjusted gas pressure, the air shutter may need to be opened, or you may be supplying fuel the oven isn't designed to handle. Don't use natural gas in liquid propane stove or vice-versa.

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?

Yes the burner needs cleaning . Yellow is lack of air causing soot and co2 . turn off do not use . needs a service and to find out why its sooting

There are several things that can cause this:

Check for blockage in the flue pipe or improper flue design resulting in inadequate venting.
One way to quickly determine a venting issue is to visually observe the flame on the burn tray. It should NOT be yellow and should burn evenly across the burner. There should NOT be any areas of the burner that appear to burned or deteriorated. Look for evidence of leaks,

You may need to dismantle the top section of the heater to visually inspect for sooting.
You may need to inspect the flame sensor mechanism (if applicable) for dirt or sooting.

If it is determined that your exchanger is sooted up, you have a blockage in the flue pipe or improperly designed flue.

It shouldn't be burning yellow and emitting soot at all;sounds like on of these possible causes-
(a)blocked burner airways(this can lead to yellow tipping and sooting on LPG powered appliances because insufficient air is getting through to the burner causing it;you can also get this effect on LPG barbecues say if dead insects or spiderwebs are in the burner pipes and airways after a period of storage),
(b)incorrect aeration being set when the burner was converted using LPG jets(too much gas and not enough air causing yellow flames/smells and sooting),
or (c) if you use propane cylinder gas a dicky or faulty regulator. I would get it looked at investigating all the possibilities I mention and taking action to correct this where necessary ie clearing the burner airways(if this is causing your problem), adjusting the aeration in the burners until you get a clear noiseless blue flame without any excessive yellow and sooting(but even after good adjustment you may find still get a very slight yellow tip without sooting at the top of the flame;this does happen with propane gas and there is a slight tendancy for this to happen more often with butane-butane tends to display very slight yellow tips on ignition increasing slightly as the burner warms up to full temperature) or if you use propane cylinder gas replacing the regulator if that is necessary.

Your range needs servicing.
The burners need to be cleaned and the air shutters adjusted.

The DPF is designed to 'Burn off' the soot deposits that accumulate, but in order for this to happen the exhaust has to become really hot. The DPF will fill up if the vehicle does a lot of short trips and the exhaust fails to get hot. The cure is a long hard drive

The manifold needs to be cleaned and adjusted could have rust etc in it Not a good thing to do yourself unless you know what you are doing

sounds like you migt have had a flash fire in the vent line. you need to open the dryer and clean out the vent line
