If there are any pigtails in the junction box (wirenuts) undo them and re-do them to make sure there is a good connection. Could be getting some minor arcing or a high resistance contact if they're not solid.

In addition to this, double check there isn't aluminum wiring mixed with other non-aluminum stuff; the thermal expansion is different between Al and other metals Cu/Brass, etc, causing joints to weaken over time. Once loose they arc routinely with any vibrations in the house, getting looser and looser with time, eventually becoming a fire hazard.

I just had to address this in my place. Expensive mess but I’ll sleep better now. If anyone is wondering I opted to use the AlumiConn connectors. Best I could do without opening up more walls and ceilings.

Every time I open up a fixture or outlet in my house I remediate the mixed-metal wiring with AlumiConn connectors. They're kind of expensive and a hassle to get crammed back into the box, but it's a hell of a lot better than spending $??,000 to rewire the whole house, and it's supposedly a permanent remediation method.

Not a shill, just a guy who bought a house from an idiot.

Lol. Must have been the same idiot I bought from. I do know that I no longer have any aluminum in outlet, switch, or light junction boxes. We rewired the bulk of the house when we purchased it. Which leads me to believe the aluminum wiring I found in a wall I was demoing recently is connected to copper in the attic (I contracted out the attic and main panel work). Guess I need to get up there with another box of these connectors.

Unless you are used to doing this id advise against that. Some older homes are aluminum wiring. You need to add certain wire nuts as well as looking for burnt wires.
