Hi all, I need help identifying this component. It’s from an Air-condition board. This is the second time I come across this type of component and I don’t know how to test it. I am trying to upload a picture of it but don’t know how.
have a look at this page but basically, u can use imgur.com to upload the image there and then post a link to that image here in your comment. https://mrcarlsonslab.com/community/general-chat/image-hosting-services/paged/2/#post-464 and the end result should be that the image would actually be shown directly here within your own post.

We’re you able to figure out your component?
@kaf Sorry for the long delay, been busy with work, but I was not able to identify the component. here ias a link to a picture of the component. It is labled DSA1

@calitechltd1gmail-com : I could be wrong but…to me it is very likely to be a voltage spike discharge device . The dead give away is the fact that it has a cut out clearance below it on the PCB material. Certain High End multimeters have those. Ian Jones (the Australian YouTuber) has done a tear down demo of a Japanese Multimeter HIOKI DT4256 (in which he briefly talks about it) and he calls it ” a staged discharge tube”. Keep in mind that different manufacturers will make their own tube that will have certain size and a certain form factor. So they won’t be all the same even though the working principle is the same:

When testing with a multimeter is should test like an open circuit since the component will only short out in the presence of a high voltage spike or some kind of transient voltage level.
@ovi4 Thank you once again for your response. I will check the Ian Johnson YouTube channel. Thanks.
DSA matches up with “spark arrestor”, the first word could be many things. I can’t view the picture but it matches our guesses by the sound of it. More modern terminology is TVS or transient voltage suppression (TVS diode).
Radios + Tubes + Scopes + Cars= Nothing better!
