Thermador Oven Repair Dual Fuel PRD48WDSGU

Atlanta City Appliance Repair — Serving Alpharetta, Roswell, Sandy Springs, Buckhead, Johns Creek & North Atlanta

Older Thermador 48-inch double-oven ranges are legendary in high-end kitchens across Atlanta. Many of these units — including the GPS486GLS and similar Pro Grand / Pro Harmony models — have been running strong for 15–25+ years. When homeowners call us for Thermador oven repair in Atlanta, they’re often surprised to learn that these older professional ranges are not only repairable, but often worth restoring instead of replacing.

Below is a complete guide to understanding why these units last so long, why they develop ignition or burner issues over time, and why restoring them is often the smartest option for Atlanta homeowners.

🔧 Why Older Thermador 48″ Ranges Start Having Issues

Although Thermador ranges are built extremely well, years of everyday cooking eventually lead to grease buildup deep inside the cooktop. In Atlanta — where many families cook frequently, host holidays, and regularly use their professional-style ranges — this buildup becomes one of the most common reasons for service calls.

Grease can work its way into:

  • Burners
  • Igniters
  • Venturi tubes
  • Venturi nuts
  • Gas delivery tubes
  • Hardware and internal brackets

Once these components are saturated, you may notice:

  • Burners won’t ignite
  • Igniters constantly click
  • Weak or uneven flame
  • Delayed ignition
  • Popping or lifting flames
  • Gas smell when attempting to light

Because the contamination is internal, these issues cannot be resolved with surface cleaning. This is where professional Thermador Oven Repair becomes essential.

How Atlanta City Appliance Repair Restores Older Thermador Ranges

To fully restore performance and safety, we perform a top-end rebuild, replacing the major components affected by grease and age:

✔ Burners
✔ Igniters
✔ Venturi & venturi nuts
✔ Gas tubes
✔ Burner assemblies
✔ Any deteriorated wiring or hardware

This approach returns the range to near-factory performance, giving Atlanta homeowners many more years of reliable cooking.

📦 Parts Availability for Older Thermador Ranges

Because Thermador is part of Bosch, many original components were produced in large quantities. However, with older models, part availability in 2025 looks like this:

  • Some parts are still available new
  • Some have become discontinued
  • Many are available as refurbished OEM components
  • Some must be sourced from “new old stock” sellers
  • A few come from specialty Thermador parts suppliers

At Atlanta City Appliance Repair, we source OEM, refurbished OEM, and specialty parts from trusted national suppliers to make complete restorations possible.

💰 Repairing vs. Replacing: What Atlanta Homeowners Need to Know

Buying a new 48″ Thermador range is a major investment. In Atlanta, prices typically look like this:

New Thermador 48″ Range Cost:

$10,000 – $20,000+

And replacement often requires additional costs:

  • Gas line adjustments
  • Electrical modifications
  • Cabinet trimming (new models are often deeper)
  • Countertop modifications
  • Ventilation adjustments
  • Haul-away of old unit

Most total replacements quickly reach $12,000–$25,000.

For most Atlanta homeowners, restoring the existing Thermador with a proper Thermador Oven Repair service is far more economical — and preserves a range that was built with higher long-term durability than many modern alternatives.
