I recently installed a 2477D next to my 2486 (v45) and now every time any switch on that circuit breaker gets turned off or on, the 2486 shuts off (all lights go off) for about 2 seconds then comes back on. There are about 5 - 2477D's and 3 - 2477S's on that circuit breaker.

Even when I press one of the buttons on the 2486, its shuts off for the 2 seconds but does control what I have the button programmed for.

Any ideas? Switch going bad? Could be a neutral or ground not connected properly?

You may have a bad connection on the hot lead of the KPL

You can also try doing a factory reset on the 2486 by pulling out the set button, then pushing it in and holding it in, the KPL will beep, continue to hold the set button in until the beeping stops. If the reset was successful the load on the KPL will turn on

Thanks Techman

I ended up having to replace the 2486. After factory resetting it and moving it to different circuits, it acted the same.

It does sound like it has started to fail.

One side note on the Factory reset. The early revisions did not have a beeper and you just held in the set button or three seconds and released it.
