You expect the kind of reliability from your gas grill that you get from any of your kitchen appliances. Unfortunately, this appliance sits outside in the cold and heat, rain and sun and takes a lot of punishment. It also has its own fuel supply and all that goes with that. This can cause your gas grill to act up and not work properly. Usually there are a few tricks you can try before you start flipping through the yellow pages.
First of all let me say that if your grill is getting on in years, has been experiencing increasing problems for a while or shows signs of rust, wear or age in its internal parts then it is probably in need of repair. Let’s face the fact that gas grills generally don’t last forever and many lower quality models only last a few years.
However, if your grill is relatively new and in good shape and if it has suddenly started acting up, then you can probably get it back to good working order quickly and easily.
Always make sure that you have turned off your tank valve and disconnected your grill from its fuel source before you do any work on your grill. If you have had your grill on, make sure it has cooled down. If you have had the gas on, give the grill five minutes for the gas to dissipate.
1. Low Flame, Low Temperature, Yellow Flame. This has become the biggest problem with many gas grills these days and it’s almost always because of the regulator (the funny UFO shaped thing on the gas hose). Regulators seem to be stickier these days and when they stick you don’t get enough gas to generate a good grilling temperature. To get your regulator unstuck you need to release the pressure on it. Follow these steps exactly:
1. Turn off the gas at the propane tank
2. Disconnect the gas line from the tank
3. Open the grill lid
4. Turn all control valves to high
5. Wait for about a minute
6. Turn all control valves to off
7. Reconnect the gas line to the tank
8. Slowly turn on the gas at the tank
9. Light the grill normally
10. Your grill should now heat normally
To keep the regulator from sticking again make sure that you turn off the control valves first, then turn off the tank valve. Always open your tank valve slowly.
If this doesn’t work give it a second try. If you still have low flame then you probably have a faulty regulator that will need to be replaced.
2. Uneven Heating/Hot Spots: Most gas grills have uneven heating. Of course this doesn’t mean that one part gets volcanic hot while other areas are cool enough to park your drink. The number one cause of uneven heating is a blocked burner. Burners have a series of holes or ports along the sides that gas flows through to produce flame. Frequently drippings run over the burner and clog parts of it.
Typically you can use a wire brush to remove these deposits from the burner and you should be in good shape. Sometimes the burners become so clogged that you will have to remove the burner from the grill to clean it.
