Help with Perun v3 Hybrid. Keeps dying

[Sam-Bristol123]

Have had 4 Perun V3 hybrid MOSFETs in the same LCTAk74. I'm unsure why but they all suddenly stop working randomly. Have tried a new motor and battery. They all work fine for the varying amounts of time then Will just cut out and no matter how many batteries I try they will not come back on. Even if I unplug the Motor they wont go into diagnostics mode. The wiring isn't caught or damaged, at this point I have been babying everything. Perun customer service has been brilliant and I have had it repaired each time but its over a month wait each time due to them being in Poland. Lots of forums I have read about them has been nothing but praise and at this point something clearly is wrong with my gun but when I use my old Gate Pico SSR MOSFET that works perfectly.

Ask perun when they repair it what fault is. The fault/failure may be a good guide as to where to look for the the cause.
