Thermador HDDW36FS
The HDDW36FS hood is notable for its shape, a box with a height range from 26 3/4 to 42 1/2 inches that comes from its telescoping chimney, and a depth of only 17 inches. That is shallow for a 36-inch hood, so it sits close to the wall. Thermador lists HDDB36WS as its successor.
Because the chimney extends, the first thing we check is how it is installed against the ceiling or soffit, and whether the sections meet cleanly. Movement there can produce noise that sounds like a motor problem.
The control is a touch panel with a 7-segment display, and speed is selected in three stages plus an intensive setting. If the display shows nothing or the intensive setting is ignored, we separate a panel problem from a motor problem by measuring the blower output directly. The cassette filters are the other half of any weak-draw call, so they are cleaned or inspected on every visit.
It is a higher output stage above the three normal ones, for heavy cooking. If it fails while the other stages work, we look at the control output and motor winding.
Note the digits and when they appeared. Thermador's manual explains display readings, and we use it together with a test of the board. A photo of the display helps.
A little movement should not occur. We tighten the mounting and check that the sections fit, because it can add noise and put stress on wiring.
