Harry S. for Model Number thermador wd24QB warming drawer I turned the control knob and it doesn't turn on? What could it be?
Answer Hi. First inspect the drawer external ON/OFF switch part # 00189432 to see if the drawer actually engages it when pushed closed for safety. The thermostat part # 00189418 has to close and send voltage to the drawer heater part # 00486314. Ohm these parts out for closed continuity to be able to utilize power. Thank You. Read More...
