There should be a packing nut on the shaft of the valve. If you can get at it, you can back the packing nut off and probably get the valve open then.

Do not try to force the knob too hard as it may break

Won't heat up above 200 degrees.


Try turning off the valve to the tank, then leave the knobs on the grill open for 2-3 minutes. Turn off the grill knobs, slowly, slowly open the valve on the tank. Relight the grill and see if it gets hot.

Grill worked fine for almost a year but I recently used charcoal following the directions in the manual (and it worked great). However since using it (& it is long gone), if I turn grill on high,...


Kathleen, the ash and debris left from the charcoal clogged the burners and caused the flames to shoot back thru the venturi valves, which is causing the flames to reach the control knobs. For the most part. I would suspect that the control panel, the electronic ignition, control knobs, the gas manifold for the burners and the burners are now completely shot.

Now, you're at the stage of determining is it worth it, to replace all the parts (if you can find them) and repair the grill. Since you didn't mention who the manufacturer of the grill is and how long you've had it. I have no way to tell how much it's worth. But, if it were me, and the grill is at least 5 years old and it originally cost $600.00 or less, I'd seriously consider replacing the gas grill with a new one. And if you want to do some charcoal grilling, get a separate inexpensive charcoal grill and take good care of it. During the weekday evenings when you don;t have time for charcoal grill to preheat, use the gas grill. On weekends, use the charcoal grill if you like.

Hope this helped answer your question and ultimately help you make the right decision.

Flames are shooting out of the grill area by the front knobs


I have had this happen & it is because your tube is clogged with a spiders web, I can about guarentee it; this happened to me 2 years in a row. Simply turn off the propane & disconnect the tank.....take off the grill grate & flame hood ....remove the tube & look inside it & see if its clogged....clean & put it back & everything should be fine.

No you need to replace the valve behind the knob as well most likely this is what caused the flame.

Gas grill lights but doesn't get very hot


I had this same problem especially when the tank on my 5 burner 2 year-old Kenmore was about half full. The solution above fixed it. I was used to opening the gas fully, turning one burner to high and clicking the button. If I would have read the front of the grill I would have seen that this was incorrect. I turned off the grill completely, unhooked the regulator and reconnected it. With one burner on high I began clicking the button BEFORE I turned on the gas. I slowly turned the gas on one quarter turn and it lit up full flame. I slowly turned the gas another quarter turn and lit the second burner. I slowly opened the gas all the way and lit the third and so on. That did the trick!

Since 1995 all regulators (the part that attaches to the gas tank to regulate the flow of gas) have included a safety device that restricts the flow of gas in the event of a gas leak. This safety device can be inadvertently activated in two ways, putting the grill into what is commonly called “bypass”. The first way for the device to be activated is to leave one or more burner control knobs in the “ON” position when the LP cylinder valve is opened. The second is not to wait long enough to “start” the grill after opening the LP cylinder valve. The safety device in the regulator is activated each time that the LP cylinder valve is opened. The device resets itself when the gas pressure equalizes between the closed burner control valve and the regulator, through the hose. If a burner control knob is turned on before the gas pressure can equalize, the device will remain in “bypass”. The length of time necessary to wait to “start” the grill after turning on the LP cylinder valve is dependent on the length of the hose and outside air temperature. It is always good practice to wait a few seconds after opening the LP cylinder valve before turning on the burner control knob to start the grill.
Keep in mind that the safety device reacts to a gas leak. If a grill is in bypass, the gas connections and hose should be tested for leaks with a soap and water solution.
If the grill is in bypass, after checking for gas leaks do the following to get the grill out of bypass:
To reset the gas safety device:
Open the barbecue lid.
1. Close the LP tank valve.
2. Turn your burner control knob to the OFF position.
3. Wait at least 5 minutes if the barbecue had been lit, then
4. Disconnect the hose from the LP tank.
5. Turn your burner control knob to the HIGH position.
6. Wait at least 2 minutes, and then turn the burner control knob to the OFF position.
7. Re-connect the hose to the LP tank.
Re-lighting the barbecue:
1. Open the barbecue lid.
2. SLOWLY open the LP tank valve all the way and wait 1 minute.
3. With the lid open, turn the burner control knob to the HIGH position.
4. Ignite the grill by pushing the crossover ignition button.
5. Close the barbecue lid.
6. The barbecue should reach 500 to 550 degrees in 10-15 minutes.
When you are done grilling:
1. Turn all burner control knobs to the OFF position
2. Turn off the LP tank valve last.
* Always follow the re-lighting instructions whenever you use the adapter hose and larger tank.

KENMORE Gas Grill 141-152210 Kenmore 437 sq. in cooking will only heat to 250 degrees


sudsy, this exact same thing would happen to me every time I changed a tank. I know it's nothing to do with the grill itself. I would have to seat and reseat the regulator hose to the tank a couple of times before it would start heating normally. Your model has 3 burners and I suspect that the flame is real low on each one even on the high setting. Try connecting and disconnecting the tank a couple of times and see if it comes to life. If worse comes to worse you can order a new regulator hose. Part number P3632L. Catriver..post back.
