Start with the Keep Warm setting on the PRG486NLG and you learn a lot about its health. Sitting at low heat for a long time, the oven needs a steady flame and an accurate sensor, and any drift shows right away in how a roast holds on the holiday table. This is a 48-inch gas range with two ovens, 3 cu ft and 1.3 cu ft, and Thermador now lists it as no longer available, with PRG486WLG as the successor.
Because each cavity has its own self-clean cycle, a latch problem on one does not mean the other is bad. We test them separately and watch the lock motor and the door switch.
The cooktop’s Star Burner is cleaned like any other burner, but the cap must sit level on its base. On a call, we remove the caps, clear the ports, and check the spark. If the oven is slow to ignite we measure igniter current, then verify the 120 V outlet before suggesting a part.
A weak igniter delays or interrupts the flame, while a sensor error makes the oven shut off at the wrong temperature. We test igniter current and compare the sensor with a reference thermometer.
Each cavity has its own cycle, so yes in principle, but heat radiates to the neighboring cavity. Remove racks and loose debris, keep the kitchen ventilated, and call us if the door will not unlock afterward.
SoftClose hinges use a hydraulic damper that can wear out or leak. We replace them in pairs so the door sits level and closes evenly.
