This shit just makes me appreciate the functional simplicity of regular light switches goddamn!
Cool teardown; thanks!
Absolutely.
Wow, you sure took it to the next level! Great job! The Jasco/GE switch/dimmers using very similar components to the ZooZ.
The early gen of the Ge used cheap caps that like to fail after power failure. Fixed many of them but 2 of them are stubborn.
They will power on and about one minute later they randomly turn on/off, then the relay starts to shiver inside and later it will no longer respond
but you can still get the led indicator to turn on/off. Replaced all caps, relay and the problem is still there :(
Disconnect power for couple minutes and the whole thing will repeat. Puzzling 😅
Weird, almost like the relay signal isn't strong enough or is being pulled down. Maybe the resistors are wrong values in the signal chain?
@@TechDregs Thanks for reply! :) Not sure, nothing changed, I did replace only all electrolytic caps. Usually only the 10uF is bad but that did not solve the problem on these 2 switches (ZW4005) so I changed thos 2.2uF and 220uF. it did not solve the problem. I got 2 of them both behave exactly the same.
@@TechDregs Sorry to bother you again...
I did open another switch that works fine and the only difference from those that have the relay problem is the 12V rail is 12.3V and those that do not work properly 11.85 V
Any idea if that could be my problem? What part could cause this? should I change those FB resistors to the chip? Thanks
I wouldn't think that small of a voltage difference would cause any issues, but I'm not familiar enough with those components to say, unfortunately. But those voltages are within +/-2.5%, and usually stuff isn't quite that sensitive.
@@TechDregs Thank you! You are right the problem was the relay controlling transistor.
All working again :)
