I've been trying to replace an existing Lutron Diva MLV dimmer with a new PD-5NE-BL Caseta ELV/MLV dimmer with no luck. I'm almost certain the Caseta dimmer is faulty.
My setup:
- 9x Phillips LED bulbs, 6.5W/12V/800mA bulbs wired in parallel. Model 454546
- In the box, hot, load, ground and neutral.
- Single pole (e.g. not 3-way)
- Existing dimmer is a DVLV-600P
Symptoms:
- The LED on the dimmer scans up and down (moving from the top to the bottom of the dimmer). Load lights don't work
- Eventually, the first and middle LEDs on the dimmer blink rapidly, implying a neutral wire fault (see my notes above).
Things I've tried:
- Triple checked that I have the neutral wire connected correctly (which I know is live because another switch in the same box is connected to it)
- Triple checked that I have my load and hot wires connected correctly, including ensuring that I haven't swapped them (tried swapping them, dimmer doesn't come up as expected).
- Switching between MLV and ELV modes via using the FOSS switch, including remember to save the settings
- Factory resetting the dimmer, including before doing any flip of the FOSS switch or doing any other messing around
