PH48GWT

Thermador PH48GWT

What we most often repair on units like this

  1. Illuminated buttons dim or unresponsive
  2. Grease collecting along the wide baffle-filter row
  3. Damper binding on a large duct
  4. Cold White lamps dim or flickering
  5. Hum at low speed from wheel buildup
  6. Duct run too long for the hood's airflow

Illuminated buttons are the first thing that identify the PH48GWT, and also the first thing owners notice when they stop working. They sit on the front edge of a 47 15/16″ canopy over a 48″ range, and heat and grease from below are hard on them.

At 27″ deep, this hood reaches well over the burners, which suits a heavy-duty range but increases the filter area that needs cleaning. We take out each baffle filter and look at the trough beneath, then test the damper and follow the duct, since a 48″ hood at the end of a long run loses much of its draw.

The Cold White 4.000 K lights and the four speeds are tested, along with the reminder and delay shut off. We confirm the label before we quote, and the price is written before any work. The work carries our 30-day warranty.

PH48GWTPH48GWT questions
The buttons on my PH48GWT light up but do nothing. What fails?

The button panel or the control board behind it. We test the panel connection first and tell you exactly which part is needed, with a written price.

Why is my 48" hood weak though the fan is loud?

Loud and weak often means a restricted duct, stuck damper or filters packed with grease. We check those before looking at the motor. Quiet but weak is the same story.

How do I tell a PH48GWT from a PH48GWS?

Check the model label inside the hood. The two are different versions, so we match parts to the exact number rather than the size alone.
