At 48 inches the PRG486WDH is the centerpiece of a large kitchen island or a wall of cabinetry, and it asks more of a technician than a 30-inch range does. Two oven cavities share one gas supply and one 120 V, 20 A feed, so a call that sounds like one oven can easily involve the other.
We start with the basics: does the main cavity (2 cu ft) light and hold temperature, and does the smaller left cavity (1.2 cu ft) do the same. Gas ovens depend on an igniter that draws enough current to open the valve, so a weak igniter is a common cause when the flame appears late or not at all. The griddle and the ExtraLow burners get their own checks because they are used at opposite ends of the heat range.
Thermador lists PRG486WDHT as the successor model. For a unit with Home Connect and a temperature probe, we also confirm the app connection and the probe jack before we blame the control.
Not necessarily. The two cavities have separate burners and igniters, so we test the left oven on its own. Often the repair is one igniter or sensor, and the main oven can be used meanwhile.
We inspect the probe, its jack in the cavity wall and the wiring behind it. A bent tip or a dirty socket is common, and we confirm the control sees the probe before testing any larger part.
Often yes. Many griddle issues are the burner under it, its ignition or a gas supply issue, which we can reach from the front. If the range must be moved, we shut off and disconnect the gas first.
