My DeLonghi Bend Line HFX65V20 stopped responding. I took it apart. There is a component that catches my attention, I do not know what it is or if what it has on the outside is normal or it has melted. I need help. I leave you photos so you can study it .

Summary:

Do you think that component is in bad condition?

What is that component?

Hi @jayeff,

Thanks for you answer.

Let’s me show the other board:

At first glance I cannot identify problems here. The bz1 was my hope, because I do not have the expertise to discover the problem myself if it is a component that externally seems good.

Any idea??

Thanks again,

David

Update (10/19/2020)

Hello everyone,

I was about to ressemble the Heater and I notices that the board makes a little sound when shaken. After touching, shaking, close-hearing and think it comes from inside the TOS1 (RBS31) the black box near the BZ1 boozer.

Is it a transitor? (for me to know first)

Is it suppose to have a loose piece inside?

Is it possible to be the cause for the whole board not to function?

Is it possible to verify/change this little box?

Or maybe avoid the whole board and make the heater work directly? (I doubt it but ask anyway)

EDIT:

The box is something like this:

Tilt sensor.

Thanks a lot,

David
