Thermador Hood CONNECT Light Turns Off: App Connection Failed

What CONNECT light turns off means

When the CONNECT light turns off on a Thermador Masterpiece chimney, island or VCI3B/VCI6B Home Connect hood, the appliance has failed to connect to the app. The manual points to a phone or tablet that is not on the same Wi-Fi, or a weak signal. The hood's venting itself is not described as affected. Pairing can be retried from the start.

Usual causes of CONNECT light turns off

Phone or tablet not on the same Wi-Fi
Weak Wi-Fi signal

✓ A safe check worth trying

1. Put your phone or tablet on the same Wi-Fi network as the hood. 2. Move closer to the router, or add a range extender. 3. Open the app and retry the connection. 4. If the light keeps turning off with good signal, call us.

! Why you should stop here

A network issue is the likelier cause.
We check the hood once the network is ruled out.
Written quote first.

Taking off a panel yourself does not by default void a manufacturer warranty, yet it can lead to accidental damage, and some manufacturers attach their own service terms. Read your warranty paperwork, or ask us, before you decide.

CONNECT light turns offCONNECT light turns off questions

Which Wi-Fi should my phone use?

The same network the hood is connected to, per the manual. A guest network or mobile data will keep the app from finding it. Disable any VPN or guest network.

Does this affect venting?

The source does not say it does. Run the fan on a manual setting to confirm it works. Venting and lights are controlled separately on the hood panel, so you can test them without the app.

Can you fix my router?

No, we service the hood. We can tell you whether the hood is the problem once the network checks out. That keeps the visit short and the quote honest.
