Andehh Posted July 3, 2023 Share Posted July 3, 2023 We have 2 x Vent Axia MVHR, the bigger unit (Sentinel Kinetic Plus B) is not powering on in any capaity. Vent Axia are saying 10 days+ for an engineer to come and have a look, but they were very surprised to hear it had failed as they are all line tested before dispatch apparently. Has anyone had one DoA, any thoughts on what I could try? PCB Fuse looks OK, as do the connections & everything else I can see on the board.... Many thanks, Link to comment Share on other sites More sharing options...

Andehh Posted July 3, 2023 Author Share Posted July 3, 2023 Nope, opened it as per their instructions. They were very casual, and their suggestions was to send me the PCB for me to replace. Turns out not needed, it was a miss wired BMS switch that was simply stopped it turning on at all. Disconnecting this resolved it straight away, then fault finding the wiring showed I'd caught two wires together. All sorted Link to comment Share on other sites More sharing options...
