PRG304WH

Thermador PRG304WH

What we most often repair on units like this

  1. A burner igniter that clicks without lighting, or never clicks
  2. Oven igniter glows, yet the gas does not catch
  3. Weak or uneven flame when ExtraLow is selected
  4. Bake or broil that runs hot or cold compared with the dial
  5. Discolored or warped grates or burner caps that change the flame pattern

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.

PRG304WHPRG304WH questions
One burner on my PRG304WH will not light. Is the gas supply the problem?

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.

Can I read an error code on this range?

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.

What should I do before troubleshooting a gas smell?

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.
