So, tonight’s the big night. Family and friends are on their way to celebrate an occasion. You turn on the grill to preheat it so that by the time everyone arrives the grill will be ready for grilling. Then you notice the flame is low, and that the grill is only heating up to 250 or 300 degrees Fahrenheit – or maybe it’s not even igniting!!! Before you panic and call your local BBQ Grill Repair company, read this …
Before we get to the solution …
How Regulators Work
All BBQ Gas grills have regulators and they do what the name implies – regulate Propane. Regulators have a safety mechanism inside of them called a bypass. Take a look at the bypass system image. You can see it’s in a locked position. This is what it looks like when the safety mechanism has tripped. A leak can cause this, but most of the time we find it’s because the user used the improper ignition process; all though, sometimes it’s simply a random occurrence.
The Proper Ignition Sequence
So then what is the proper ignition sequence? First, let’s identify the improper procedure.
* Side note about the shut down procedure. The following ignition procedures are written assuming you are turning the burners off 1st, then the Propane Tank. Therefore, each sequence starts from the all off positions. While it is acceptable to turn the burners off and leave the Propane Tank on, we strongly recommend you to go ahead and turn the Tank off also.
Improper Ignition Sequence.
*** Everything starting from off/closed position.
1. Turn on burners.
2. Turn on Propane.
Proper Ignition Sequence.
*** Everything must be off to start – the propane tank and burners.
1. Turn on your propane tank.
2. Now, you can turn the burners on.
Basically, the key here is to be sure to have your burners off before you turn on the Propane. This is because if you turn the burners on first the gas will not be pressurized in the hose causing the Bypass to trigger. To the system, it appears there is a gas leak; hence, the bypass triggers. (Even though there is no leak; because the back pressure is low the system will think there is.)
* When using the improper sequence, the regulator will trip because by turning the burners on 1st, you empty the lines of any propane which causes the low line pressure.
When should the Regulator Reset be performed?
1. The burner will not light with igniter or match.
2. Burner does not get hot enough.
3. Low or incomplete burner flame pattern. “Also, the flame should be blue. If it’s mostly yellow that’s an issue.”
How To Reset a Regulator
So now you know the problem, let’s get to the solution. Of course, we’re assuming you have checked your Propane Tank to see if you simply need a new Propane Tank Exchange.
1. Turn off the gas at the propane tank.
2. Disconnect the hose from the propane tank.
3. Open the lid of your BBQ Grill.
4. Turn all the burner valves to high.
5. Wait for 2 minutes.
6. Turn off all the burner valves.
7. Connect the gas line back up to the propane tank.
8. Turn the gas on slowly on the propane tank.
9. Light the grill using your normal lighting procedures.
If this solution availed no result, it’s time to call your local BBQ Grill Repair Company. There are numerous other more advanced issues that can occur. For instance, you may have a blockage in the Venturis Tubes. A blockage like this is caused by char/grease build up. You can decrease the likely hood of this ever happening by being sure to have a BBQ Grill Cleaning done regularly.
