If you own a PRG364NLG, the thing you probably bought it for sits on top: the Pedestal Star Burner, rated at 22,000 BTU for fast boiling and searing. Thermador lists this model as no longer available and names the PRG364WLG as its successor, so many of these ranges are by now well established in their kitchens.
Burners of this type are sensitive to cleaning habits. A cap left slightly off center after wiping, or a port blocked by dried sauce, changes the flame shape, and the longer star pattern then shows gaps. We lift each cap, clean the ports, and check the igniter spark and gas flow before talking about parts.
The oven side is cleaned by Superfast 2-Hour Self-Clean, which is hard on door locks and wiring. When a cycle fails, the latch and the temperature sensor are where we look first. The SoftClose hinges are the last stop on any visit, because a worn hinge is easy to overlook.
Its star shape is 56% longer than a round burner of the same size, which spreads flame more evenly across a pan. It also means that a single blocked port is easier to see in the flame pattern.
Usually moisture or debris on the igniter, or a cap that is not seated. We dry and clean the spark electrode and reseat the cap, then test ignition and flame stability.
It runs at very high heat, which stresses the door lock, control and wiring. Heavy spills should be wiped first. If a cycle ends early, we check the latch and sensors rather than simply running it again.
