Jenn air grill, only half of all 3 burner lite

I purchased my Jenn Air propane grill from Lowes over a year ago and have always been disapointed in the amount of heat it produced. It never reached over 300 degrees with all three burners lite. I just discovered only the left side of each burner lights with the spark ignitor, due to its poor positioning. The right side of each burner must be manually lite with a long stick, or the gas will leak out of the right side of each burner. I cannot believe this unit passed any safety codes, or has not blown up. The good thing is once you manually lite the second half of each burner it does get hot enough to cook food. I'm going to talk to Lowes about this, but I though anyone with a cold grill might want to know, and be aware that gas may be leaking out.

The reason the other side of the burner is not lighting is not due to poor position of the ignitor. If you remove the burner, you will see a a slot called a cross over slot underneath the rear of each of the burners. These these to be clean out as the dirty propane has caused them to clog. Burners then to be clean a mininum of at least once a year and normally at the beginnoing of the grilling season.

Although there are particles in propane gas, they are miniscule and there is no such thing as "dirty" propane. Certainly you would never plug up carry over ports on a burner from impurities in the gas.

The problem you are describing is either due to inadequate manifold/supply gas pressures, a defect in the burner assembly, such as burrs or residual stampings from the burner supplier or an error in assembly. Sometimes it can be a simple matter of resetting the primary air shutter. Too much primary air can cause a little issue with even lighting to all ports.

I would say you have a good case for the warranty department. Jenn Air is just a brand name and all of their grills are manufactured by others with the Jenn Air name just stamped on it. For a few years it was CFM/Vermont Castings that were manufacturing for them.
