Vent: That controller board on the MRL at the Grand Avenue building just fried for no reason
I was doing a routine inspection last Tuesday when the whole system went dark and the backup battery kicked in, and after digging into the logs I found a voltage spike from a bad capacitor that took out the main processor, so I had to swap the whole board on the fly while the building manager stood there tapping his foot. Has anyone else run into sudden board failures on those newer Schindler models?

Grand Avenue was built in 2015, seems like a stretch to call that a normal failure under five years old.

Grand Avenue was actually built in 2010 according to city records, not 2015 @jessica_robinson23 - that's a five year difference that changes things a bit.

Rip into that age thing because it really doesn't matter (manufacturing dates are just a suggestion half the time anyway). Five years old or ten years old, those Schindler boards are known for having cheap Chinese capacitors that dry out or blow for no good reason. I've pulled three of them out of a building built in 2022 where the backup board lasted exactly eight months before it started throwing voltage errors. The age debate is a distraction from the real problem - they're using garbage components that fail regardless of how new the building is. So yeah, river320 and jessica_robinson23, you're both right and wrong at the same time (which is the worst kind of right).
