Burner replacement I have recently replaced the original cast iron w/ ss burners. The control valve nozzle does not quite reach the venturi. This problem is exacerbated when hot, the metal expands and the nozzles pull away.

If you ermove the control panel on the fom you should be able to slide the gas manifold back a little thus putting the nozzle into the burners.

The manifold has a couple of screws at the sides

How do I swap the nozzles

Although converting the fuel in a typical barbecue is very simple it can create a very dangerous problem if done incorrectly. Many bbq companies do not permit fuel conversions because done with a know-it-all attitude instead of getting experienced, licensed assistance can be dangerous.
The "nozzles" are the gas orifices and the orifices have a small hole drilled to limit the maximum amount of gas flow into the burners. The orifices are almost always threaded to the tip of the control valve where the valve inserts into the burner venturi tube. Occasionally the valve will have an extension gas line between the tip of the control valve and the burner and in this instance the orifice will be at the end of the gas line where the gas connection slides into the burner.
This is the same in side burner range tops but in a side burner the orifice can usually be accessed by lifting the round shield and burner on the top of the side burner instead of following the gas line from the valve.

Grill burner will not burn like the other

Dynasty burners are replaceable and they are very good appliances (when they're actual dynasty, manufactured by jade).
About 90% of the time someone complains about burner flames or heat it is the check valve needing to be reset. I explained this earlier but let me know if you need to know how to do this.
On the rare occasion the check valve is not the problem (and 90% could actually be very low because this is almost always the problem!) the burner could need to be cleaned or replaced or the gas orifice and valve could need to be cleaned or replaced.
Dynasty burners are very heavy cast iron, single venturi "H" burners. Although coated cast iron is quick to oxidize and sometimes because of the coating the rust will start from the inside out. Lift the burner from the back of the barbecue and slide it away from you. Check to see if it is corroding from within.
The single venturi tube extends from the bottom of the burner into the control panel where it slides over the gas orifice at the tip of the control valve. It is possible for the gas valve to get a small insect crawl in through the orifice and build a nest inside the small cavity inside the control valve.
Remove the burner to reach through the inner firewall with a ratchet to pull the orifice and then check the inside of the orifice and the inside of the valve behind the orifice. If something is clogging the orifice the gas will flow unevenly and you may have flame-flashing inside the control panel which will destroy the lubrication in the control valves and will destroy the ignition parts inside the control panel.
I suggest the check valve solution with the drip tray removed so you can look from under the control panel for gas leaking through the air holes in the venturi tubes. Also, remove the control panel and leak-test the valve with soapy water because if previous flashing occurred the first casualty is usually the seal between the valve and the gasket which can lead to more leaking gas.
Check valve:
Turn everything off (tank and bbq).
Disconnect hose and regulator from LP tank.
With tank disconnected, turn the BBQ on. Turn every valve to "high" and leave it for 5 minutes.
Turn everything off -- completely off.
Reconnect tank but turn the tank on very, very slow. The check valve problem occurs when gas "hits" a swing arm too hard as the gas leaves the cylinder so turn the cylinder on very slow and then relight the grill.

My control knobs are getting really hot and are actually melting

Sounds like the Venturi Valves on the burner may be partially clogged and the flame is big firing around the burner orifice. This is fixable, but requires removing and cleaning all the burners and their venturi valves.

One other thing it might be, and this will depend on how old the grill is and how well cared for the grill is. The burner's manifold may be leaking. That's a more serious problem, that requires quite a bit of work to replace.

Go with the first solution first and if the doesn't solve the problem, it will be the second one.

Hope this helps you troubleshoot and solve the problem.

My knobs get to hot to touch when turning off

More than likely, the vinturi valve on each burner is clogged and the burners flames are back firing and reaching the control knobs. Stop using the grill, until you disassemble the burners, clean them and the venturi valves, The venturi is an opening on the sides of the burner, where it slides of each burner orifice. Spiders like to build nest in them.

For a more visual look at what I'm talking about, go to the follwing link for Sure Fire Heat. They manufactured the grill for Amana. Go down the list of Amana grills until you find yours or one like it. In the Owners Manual there should be a section on Maintenance, which will show you how to remove the burners and clean them.

Hope this helps you solve the problem.

Regarding charmglow 720-0289. can't get a hot enough flame. cleaned all burners and made sure all orficis on the burner were clear even blew out with air hose

Are the burner flames diminishing as you turn on additional burners? In other words, is the flame size correct when one burner is lit, but too small when several burners are lit? Is the flame a nice blue color or yellow? If yellow, adjust each burner's air shutter at the end over each orifice. Have you tried adjusting the pressure on your propane regulator? (If it's red, don't mess with it) If it's a silver regulator and has a center cap, you can remove the cap to adjust the screw inside, by turning it clockwise in 1/4 intervals until the desired flame size has been reached. It's also possible that your burners have corroded closed somewhat. Do you have cast iron or stainless steel burners? Cast iron burners tend to corrode shut over the years due to moisture. Stainless steel burners just tend to rust away and flake, but usually become flare ups or out of control flames. Anyway, that gives you some things to look at. Hope it helps. Douglas

This 'adjustable plate' is known as an 'air shutter' located at the tips of the venturri tubes which are the tubes that carry the propane from the valve to the burner. These air shutters allow you to control your flame by mixing oxygen with propane to create a yellow flame to a blue flame. The perfect flame is a uniform blue flame with a small yellow tip.

Unfortunately, these air shutters are considered part of the burner itself and cannot be individually replaced. However, if the burner and venturri tubes are separate from each other, you may be able to get a replacement venturri tube without having to replace the entire burner unit.

Hope this helps.
