Hi there, I have a mini controller MC460 that I used for many years without problem. Last month I unplugged the unit during couple weeks for room painting. When I plugged back the controller to the same outlet, it no longer control anything and the red led stays on all the time. I tried to connect it in a different house many miles away and the red led still stays on. I opened up the housing of the MC460 and made sure there were no switch stuck on. When I press any of the bubble like on the board, I can still hear the clic like it should be. I have skills to measure or replace electronic parts so if you have any idea, I'd be happy to try it before throwing the unit to garbage. Thanks. Yves
