SOURCE: Coleman propane stove problem

The connector for attaching the regulator to a disposable propane cylinder has a sintered bronze filter in the tip of the brass probe tube that is prone to clogging, or the bronze pellets get mashed down over time, restricting gas flow, and this will cause a portable grill or camp stove to perform poorly. The filter is so fine that it takes very good eyesight and bright light to see that it isn't solid metal, or use of a strong magnifying lens. The best solution is to buy a new Coleman regulator assembly. If you are unable to get a new regulator assembly and have the skills and the tools, you can try drilling a very small hole on the side of the probe tube with a #60 drill bit, just below the bronze filter, but near enough the end of the tube so that the hole will be past the plastic seal when the disposable cylinder is fully screwed into place. You should avoid drilling directly into the end of the probe tube, as the end of it is used to depress the Schrader valve in the disposable cylinder to allow gas to flow. A #60 wire gauge drill bit is only 0.040 inch (1.016 mm) in diameter, but makes a hole large enough to supply sufficient gas to a portable grill or a dual-burner camp stove. If you choose to perform this work, the probe should be unscrewed from the regulator body and the Schrader valve core in the probe tube should be removed before drilling. Be sure to clean all brass and bronze particles out of the probe tube before re-installing the Schrader valve core and the screwing the probe into the regulator. Use a removable-grade thread locking compound to secure the probe in the regulator body and don't over-tighten it, so as not to crush the rubber gasket. Allow the thread locking compound to cure for several hours before attempting to use the regulator. Keep in mind that this modification increases the likelihood of dirt getting into the needle valves and jets of your stove or grill, which can cause maintenance problems in the future.1_28_2013_4_49_27_pm.jpg

The middle burner puts out gas, but the two outside burners do not.

Not enough information. If we assume the other two control valves are turned on, are the orifices clogged, are the valves leaking, are there safety valves attached the the natural gas line to detect leaks?

look down inside the valve stem to see if there is a tiny screw. this is an adjustment for the valve to allow more or less gas flow. if the valve was damaged or tampered with this could generate better flow. if the appliance went a long time without being used the valves could be clogged. remove the orifices and blow out the orifice and the valve with the orifice removed.

The brass valve "stem" that the plastic

Although this grills is no longer available, Coleman may still support it. Try contacting their Customer Support Dept 800-835-3278, if you haven't already. From what the Owner's Manual shows, what you're needing is the entire burner valve assembly. As the brass stem is not a separate part.

I hope this helped and thanks for choosing FixYa.

Other than replace the burner valve, there's not anything you can do. Apparently. it got jammed somehow, perhaps during the it's time in storage between uses or someone tried to force the valve.
Who knows? In any event, if you want to find the replacement part, go to the following link.

If you don't see the part needed ( the numbers on the exploded view of parts are incorrect) call Coleman 1-800-835-3278.

I have a Nexgrill 720-0073 stainless grill. The grill doesn't get very hot - around 200-250 and the flame level is low (BOTH sides). Tried a new tank of propane - same thing. I cleaned the burners late...

Hi and welcome to FixYa. I am Kelly.

Things that cause low flames

1. LPG Tank regulator internally corroded and diaphram can not open enough to supply the correct amount of pressure. (replacement regulator required) If you do an tapping on the regulator disconnect it from the tank and if you do strike it... use WOOD! Tap from bottom and then from top.... several times. When your done... do it one more time. This may correct the problem for a short period but if it is corroded internally the problem will repeat in as little as a month.

2. The orifice holes are restricted due to spider webs insects ets. (Remove burner and Physically clean the orifice mounted on the back of the gas valve.) Worst case the orifice has to be removed and the mini orifice hole cleaned.

3. Clogged internal burner air / gas passage (remove again and clean) Use a tooth pick to clean main burner holes. Use spot tie or something long and skinny to probe into the burner air / gas passage. (Wire coat hanger works too)

4. The burner gas valves on the stem nut side are coated with grease not allowing full movement of the valve stem inside the gas valve. (remove and clean with engine degreaser)

Thanks for choosing FixYa.

Flare behind temperature knobs on jenn-air gas grill

This seems to be a problem for most Jenn-Air users. The burners are defective, rusted or clogged and allowing the flame to "back up." You most likely have a melted electronic ignitor as well as gas valve damage. The new burners that I received this week for my model 720-0061-LP are 1/2 inch shorter than previous versions. Time will tell if this fixed the problem. I would call Nexgrill and get all new burners and inspect the gas valve area for damage. Since 2004, I am on my 5th set of burners, glad they were free since I have a lifetime warranty on my model.

Gas coming out near burner knobs

The issue is with the valve that is connected to the knob. it is poorly designed. To fix it take off the lid assembly and remove the front black cover that covers the knobs. remove the almost diamond shaped metal piece that the knob shaft runs through. put on your gas tank and adjust the valve to a position where no gas comes through.. might be lucky or you will have to replace that valve.

Burner doesn't turn off

If the burner stays on and will not go off, the gas valve or furnace limit switch is defective. Immediately turn off the gas to the furnace by turning the inlet valve so that it is perpendicular to the gas pipe. Call your utility company or a furnace repair technician.
