To be honest M_C I didn't notice the pictures, I'm just going off experience from having one fail on me and knowing a couple of others who had the same failure. Those were the round-type Thermistors and they did stop the VFD from starting. But to be honest, this was quite a long time ago now, at least 6 yrs ago and the newer Huanyang VFDs we fit now are much better made and those pics do look different from the one which blew on me so you could very well be correct.
Also, I haven't had an Huanyang VFD go faulty now for at least 4yrs and I've fit over 40 sets just in the last 12 months and probably 200+ in the last 5yrs, so I'd say they are fairly reliable now.
