I have a dimmer switch (PD-6WCL-WH/PD-10NXD) that worked well for 3 months. It used to turn on and off automatically based on the schedule I set in the Lutron APP. Last week, it suddenly failed to turn on in the evening . I pulled out the FASS tab and pushed it back in, but it didn't work. I had to remove it from the wall and reconnected each wire, but it still failed to work.
So, I bought a brand-new one on Amazon and installed it yesterday. The same thing happened again. The switch indicator could move to the 'On' position, but the light did not turn on. The only way to turn on the light is through the Lutron APP.
I am so confused and frustrated. I would be grateful if you could help me solve this problem.
