Question about Thermador HDW36TS Stainless Steel Kitchen Hood

Open Question

I have Thermador HDW36TS range hood/fan with Elica motors S80-40ARP7701UL. There are three fan speeds. When the fan is on any speed the second speed light blinks continuously. Is this a signal that something is wrong? Please explain.

SOURCE: My customer has a Thermador

Wow, this is a situation, for sure. If the motor has a 3 wire system, the ground could be connected to the middle winding, and then both speeds would be the same. I would really check the wiring to the motor, as well as the switch. That's all I can think of, unless there is a crazy short, somehow.

KWCU405SSS fan motor high speed only


Agreed! It totally works. Our fan and lights were stuck on high. Flipped the hood circuit breaker off for 30 seconds then back on again and all controls are working normally again. Thanks!

The speed module is very simple: a triac with some extra components to modulate it, it's build exactly the same as the one from a vacuum. That speed module is controlled from the touch screen - are you sure the touch screen is operational? That's relatively easy to test - just put a potentiometer where the control signal goes and see if moving the potentiometer changes the speed.

BABT83.2AL Canopy Rangehood The fan/suction is not working. A slight straining noise is heard. The light is working as is the display panel.


These units have a history of fan failure due to inferior 220 volt Italian fan.

I have just had fan fail and retrofitted a ebmpapst blower fan model D2E146HT6702 which is readily available in Aus for around $120.

The fan speed control is by inverter variable output so you don't use all the speed select wires that this fan has. Connect the Red wire on the range hood to the Black on the motor (High speed winding) and the Black on the range hood to the Blue on the motor (Neutral) and the earth to the earth (Green).

Disconnect and toss the cap in the white enclosure under the PC board enclosure (the new fan has the cap on board). Don't know how easy to fit in the range hood as mine is in an acoustic fan housing in the roof (makes it wisper quiet when running)
