Gas Grill Regulator Can Slow Your Grill to a Crawl and Never Reach High Heat!

Low flame, low temperature, yellow flame: This has become the biggest problem with many 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
11. 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.
