My flame is very low when lite and grill will not get beyond 200 degrees. This happens intermittingly.

You need a liquid vapour mechanical thermostat ( control knob & thermostat).this will activate the low flame procedure as it should, you need to use a gas safe engineer to fit and test your appliance controls, this will be done to makesure your appliance is safe to use once the repair has been carried out.

If you are using a 20Lb LP Gas Tank, rather than hard piped to the grill or you're using Natural Ga, here in may lie the problem. If it is Natural Gas, was the grill converted or ordered for Natural Gas? If not, that's why it' not heating well.

If you're using a 20Lb grill tank, do the following:

1. Turn the Propane Tank Valve OFF and disconnect the hose from the tank.

2.Wait 5 minutes and reconnect the hose to the tank. Open the tank valve VERY, VERY SLOWLY (Slow motion, slow).

3. Once the valve is fully open, light the burner farthest from the tank first and turn the control knob to HIGH. Does the flame height look correct for being on HIGH? If so, light the remaining burners the same way, Do all the flame hieghts look correct? If co, close the lid and allow the grill to preheat for at least 20 minutes. Did the grill thermometer go higher that 200 degrees F. If so, you solved the problem. Always remember to turn the tank valve ON very, very slowly.

If that did not solve the problem, the thermometer may be incorrect/faulty. I had this happen myself, with a new grill. To test it, invest $5.00 in an Oven Thermometer, like you use in a regular oven, It sits on the oven shelf. But, in this case it will sit on the center of the grill's cooking grates.

Light the grill and preheat it for 20 minutes. Loo k at the grill thermometer and then lift the hood and look at the oven thermometer. The oven thermometer may be as much as 200 degrees higher. That's because it's actually reading the temperature at cooking level, not up in the air, where the grill thermometer is.

I never replaced my grill thermometer. I continue to use the inexpensive oven thermometer, because it's giving me the actual temperature, at the level I'm grilling at. And I, do a lot of grilling.

Hope this helped you troubleshoot and solve the problem. Pleas let me know and Happy Grilling.

Hi,
Your problem could be or probably is with the regulator...not enough gaspressure...

Propane, LP, or Natural Gas Regulator Problems
heatman101 ,,./,./

Fuel starvation is the likely cause. Pressure regulator is bad, or an orifice is clogged.

It could be a couple of things. First you could be low on propane or natural gas depending on what you use. The second thing is that over time the little holes in the burners clog. You can poke them clean with a toothpick. Or if they are rusted you will need new ones which you can find from an appliance parts dealer. If they don't have your part start looking on ebay because your grill is discontinued. Jenn-Air might be able to help you find the parts if you can get in touch with a customer service rep.

Try replacing the regulator and hose, not very expensive and fairly easy to do. If that doesn't help, let me know.

yes you can use some oven cleaner on them

Hello,

Check the excess flow safety device, which is part if the barbeque to cylinder connection, may have activated. To reset the excess flow safety device turn all burner control knobs and the cylinder valve off.
Disconnect the regulator from the cylinder. Turn burner control knobs to high. Wait at least 1 minute . Turn burner control knobs OFF. Reconnect the regulator to the cylinder. turn cylinder valve slowly. I HAD THIS PROBLEM JUST LAST NIGHT AND FIXED IT RIGHT THEN.
