Thermador’s Pro Grand range line began somewhere, and the PRD304EG is a documented part of that beginning, backed by a Service Manual 94 pages long. The manual cross-references a large family of siblings in 30, 36, and 48-inch sizes and several gas configurations, such as PRD364EDG, PRD366EG, and PRD484ECG. Owners of ranges this old and this far past warranty have few places to turn, even though the PRD304EG was clearly built as a serviceable, documented product.
Expect age to matter as much as any single broken part. Igniters age, thermostats drift, and door seals wear after decades of heat cycling.
Whenever a burner will not light and you smell gas, close the range’s gas valve before any other step. Valves and gas lines have had longer to wear on a range this old, so the rule counts for more here.
Yes. Thermador published a Service Manual for this model, 94 pages long, and it lists related siblings. That documentation lets us identify parts and procedures instead of guessing.
Worn igniters, drifting thermostats, and tired door seals all slow an old oven. We test each one. We rank the likely causes and tell you which is the most probable.
That is your call, and we give the repair cost in writing before any work so you can compare. You will see the written price before any work begins.
