The PRG304WH has a gas oven of 4.4 cu ft under a cooktop of four open Pedestal Star burners. Thermador sells it as a 30-inch, all-gas Pro Harmony model, built to the standard 24-inch cabinet depth and not the deeper Pro Grand commercial size. With 87,000 BTU in total across the cooktop and no electric oven to confuse things, most calls fall into two groups: ignition or flame at one burner, or bake and broil performance in the single gas oven.
All the burners and the oven igniter draw from one gas supply. When more than one fails to light at the same time, we look at the supply line before assuming several igniters died on the same day.
Smell gas, or hear a burner light late with a pop? Close the range’s gas valve first. Because this one is 120V only and lacks Home Connect, we work from what we can see and hear instead of from an app.
Rarely. One dead burner nearly always traces to its own igniter or orifice. Several burners quitting around the same time is the pattern that sends us to the supply side.
No. It is not Home Connect WiFi-enabled, so there is no app-based code to check. Diagnosis comes from watching the burner, igniter, and oven directly.
Close the gas valve at the range first. Only then should anyone look at an igniter or burner. That makes the physical checks at the burner and oven the heart of every visit.
