Two telescopic racks of different sizes and two broiler pans hint at how this range is used: a big oven for the main dish, a small one for everything else. The PRG486WLG is a 48-inch Gas Professional Range with a 3 cu ft cavity and a 1.3 cu ft one, and its service pattern follows that split.
The first question on a call is whether both ovens are affected. If only the smaller one fails to ignite, the igniter or valve is in focus. If both are off, the gas supply, the control or the 120 V, 20 A feed gets attention. On top, the QuickClean Base is designed to catch spills, but it needs regular wiping, otherwise burned-on residue smokes when the burner is used.
Thermador lists this model with no successor named. Home Connect and the Color TFT display are tested for pairing and touch response, and the temperature sensor is compared with a reference thermometer.
It is a basin under the burners that catches spills so they are easier to wipe. If it is neglected, residue burns and smokes, and can reach the igniters. We clean it and inspect the electrodes.
Usually the working one, but ask us first. If the issue is gas supply or the control, we may advise using neither until we have checked it.
The simmer setting depends on the valve and a clean port. We clean first and test the low flame; any valve adjustment is made carefully and checked against the manual.
