I have a coleman 4000 grill and need a new valve assembly any idea were i can get one?

A complete new valve assembly isn't very expensive and you can often get one on eBay with a new generator included. It's not worth servicing the old valve given the safety implications of leaking fuel.

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.

jcw - It sounds like the regulator is locked up from turning on the gas tank valve. Happens a lot with the new OPD Valves on the grill tanks.

1. Turn the tank valve OFF and disconnect the hose from the tank.
2. Turn the burner(s) ON for 1 Minute, Then turn them OFF.
3. After 5 minutes reconnect the hose to the tank and open the valve VERY, VERY, SLOWLY (Slow
motion, slow).
4. Once the tank valve is fully open light one burner and turn it to HIGH. Did the burner light and
does the flame height look correct? Id so, light the remaining burner the way. Did it light and the
flame height look correct? If so, you solved the problem (with a little help).

If the above didn't solve the problem, the Hose/regulator Assembly needs to be replaced. What happened was this, when you turned the tank upside to "burp" the tank. The OPD Valve shot a hot load of gas to the regulator, when you opened it as you normally would and permanently locked up the grill's regulator. That "burping" trick used to work with the old style tanks. Won't work with the new ones. You can get a new hose/regulator assembly at any home center or hardware store, that sells grills and accessories. They run about $30.00. Take your old one with you for comparison purposes. Once you install the new one and connect it to the tank. Open the Valve Very, Very Slowly, until it is fully open. Or you may have the same problem again.

Hope this helped to solve the problem. Happy Grilling!!

Layla, it's a a common problem and one that's easy to fix. Turn OFF the tank valve and if you're using a 20 lb LP Gas Grill Tank, disconnect the hose from the tank If you're using an insert-able gas tank remove it from the grill. In either case, leave the gas disconnected for 5 minutes, Then reattach the hose or reinsert the tan and turn the tank valve ON VERY, VERY Slowly (Slow motion, slow). Once the valve is fully open, light the burner and turn the flame to the highest setting. Does the flame height now, look correct? If so, light any remaining burners the same way and check their flame height. If they all look correct, you've solved the problem. If not, the gas regulator/hose assembly (if you're using the 20 lb tank) needs to be replaced. If you're using the insert-able canister, just the regulator needs to be replaced. Either way, you're fortunate that your grill is new and still under warranty.
Contact Coleman Customer Service 800-835-3278 for free replacement parts or the nearest service center to you.

Hope this helped you. Please let me know. Thanks

Assuming your tank is a least half full - Turn the tank Valve to OFF. Disconnect the hose from the tank and wait 5 -minutes. Then reconnect the hose to the tank and turn the tank valve ON VERY,VERY SLOWLY (Slow motion, slow). Once the tank valve is fully open light the burner farthest from the tank first and once it's lit, turn it to HIGH. Light the remaining burner(s) the same way. Does the flame height look as it should? If so, you solved the problem. If not, you'll need to replace the grill hose/regulator assembly. If that's necessary, since your grill is new, the warranty should cover it. Just make sure you have your Proof of Purchase.

Hope this helps you solve the problem. Happy Grilling!!

Take the entire grill to your local propane company, so they can look at it and replace it on site for you. Call around first, as some places no longer have a repairman on site at any given time.

Have you tried to tighten the generator onto the valve assembly using pliers? This worked for me.

This might be of help..

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.
