Replaced two electrical switches, now two outlets flash, work shortly or not at all
In one receptacle box, I replaced the 3 way switch for the porch with a 15v 120w switch, I replaced the one next to it with a dimmer switch for the entryway light.
From there, there are two outlets that run off that, there wasn't a probably until about 3 days later when the switches still worked but the optwo outlets stopped working.
Every now and then they will flash and flicker and possibly turn back on for a night then turn off early the next evening.
Still, the outside 3 way switch and the entry dimmer switch still work nicely. So I figured there was a loose connection, I took off the outlet covers for the outlets themselves and the switches I installed.
The outlets look to have a good connection with each outlet having two black wires and two white wires.
The switches, the three way outside switch has two black wires, one white connected, while an additional white wire is connected to two other white wires wired together with a wire connector screw.
The entry dimmer switch has one red wire and two blacks tat are connected to it, while there are two white loose wires that are twisted together with the above mentioned white wire with the wire connection screw.
Is that white wire causing the problem?
If so, how should I connect it, as it was connected before and there really isn't a different of switches that I replaced, since I replaced a 3 way with a 3 way and a regular switch with a dimmer.
