Other day while my Speedio was idle I heard a little crack and fizzle and everything shut down. When I went to Phase Perfect PT-355 unit the smoke was coming out of it. I got this delivered less than year ago on 5/3/2018. Professionally installed by licensed electrician.
Anyway I opened up the front door to check and noticed that on the back of the front door there was a burn mark. The electronic board with TAMURA part blew up:
Next day I called Phase Perfect for support and they thought that capacitors were giving out and that's what caused board to blow up. They sent new capacitors and electronics board, I paid for overnight shipping.
Got the parts, replaced the electronics board and proceeded to remove front bracket which holds these boards so I can access capacitors to replace.
What I have found is wires were totally burned out and the leg of capacitors which was bolted to the bar was not tightened properly on one side and on another side it wasn't bolted at all, the nut was found on the floor. Additionally these nuts did not have paint marks that should indicate that they were checked and torqued properly so it seems like someone at the factory got distracted and forgot to tighten them. These are photos I took before I started changing capacitors so I can record how everything was wired up:
This one not bolted down:
I tested all capacitors I took out and they measure as good, I replaced them anyway. Fuse in PT-355 also blew out. Replaced that one as well.
I think its safe to say that fault was lose connection of high voltage leg of capacitor which was arc-ing and heating up due to resistance and finally it burned out taking the system with it.
Got the unit running and to my great fears Phase Perfect took my Brother Speedio S500X1 out as well. I will have tech coming out for service next week and there is no telling what damage is. From my measuring with advice from service folks it looks like at least DC power supply is blown out. I found that fuse which is soldered to the board is blown and I am afraid that damage does not stop there since this was slow-burn, delayed fuse so contactors that open rest of the system to power were likely open when surge happened.
So if you have newer or new Phase Perfect unit I highly recommend checking electrical connections WITH POWER DISCONNECTED of course, especially at least check visually that nuts and bolts are all tight and have paint marks on them.
I will update this thread as I learn more what total for damage is and how Phase Perfect responds once I ask them to cover the repair cost.
