Hello ... new to the forum, thanks for the add. I'm long time x10 user. I had a Switchlinc 2384 master in my kitchen light circuit with 2 slave switches. The master finally failed (micro switch issue) I found a new Switchlinc 2383 on Ebay... same exact 4 wire install, side ramp led indicator, etc. I replaced the old switch, duplicating the original hookup .. The new switch accepts the Home and Unit Code, operates remotely ok .. but will not ramp up or down (dim), it is just an on off switch. I reset it to factory settings by pulling out the led button and following the procedure, reset the addresses, but no ramping. I also took the step of removing all dimmable LED bulbs from the circuit and put in a few incandescent, but it made no difference. I'm beginning to suspect I bought a bad switch. Any ideas what might be the issue here ? Thanks in advance
