Heard a loud pop in middle of night woke us up. Dead FanLinc.

Ordered a new one, should be in this week.

This one was purchased in 2019, which was replacing a previously failed one which lasted longer, probably 8 years.

I was going to look into other options for the fanlinc but not much out there and its just easier to replace this one and hopefully get another 4-5 years out of it.

 

Received new one from Aartech and installed last Friday.

Examine old one and nice and crispy...

I would like to say that installing new Fanlinc went smoothly, but had a few issues on ISY side...

Could not Add the new device in UD Mobile using the Insteon ID... seems that app only support adding Insteon using linking mode, which I could not seem to do from the fanlinc, or take time to bother figuring out. Had to run downstairs and add manually using the AC.

Replacing fanclinc did not work using the replace device feature... got a not responding error after a reboot of AC. I ended up having to delete it and re-add again using AC. Naming it the same as before and doing a reload of Home Assistant ISY integration and everything working as before.

 

Not 100% on this as I don't use any of them.

That looks like a fuse resister and the module has issues as you found out.
