CAME ZA3 Not opening & red light (program) flashing

[dj_singh]

Any update on this? My za3 likes to keep staying open, it will sometimes close by itself. Last year sensors had to be cleaned, then i bought be photosensors and it work perfectly for about 6 months now it's done it again, I've put new sensors on again but it's still the same.

I'm not sure what to do next apart from maybe fit new capacitors as they are almost 14 years old. Or get a new PCB.

Any suggestions? Also I've noticed the caps looks like a completely different design on newer came control boxes
