I faced a similar problem which was fixed thanks to you all on this blog.
Following the change of capacitors the problem was fixed at a cost of 4$.
Lets see how this one lasts.
I purchased the Insteon PLM 2413S on 28 July 2013 and installed it in August 2013. It worked flawlessly until Feb 2016 when automation just stopped.
I unplugged the unit for few minutes and reconnected, It worked for another 3 months then stopped working permanently.
I asked for advice from www.AARTECH.ca from whom I purchased the unit. They have always been honest with their product support.
On Ticket ID MWM-464-29274 - Mike from ARRTECH replied on 4 July 2016:
"We have heard of people replacing the capacitors and be successfull, but as a company we can not suggest doing that. On a good note, the newer PLM's have been good for us and not failing as the older ones have. Kind Regards. "
AARTECH sells the Insteon PLM 2413S just Under $100 Canadian plus shipping.
Thans all!
