... make sure your line Voltage isn’t running high. 120V is normal now and the line is not supposed to exceed 125V for more than a second. But I’ve seen situations were 125V was normal
If you’re talking about the US, you are mistaken @atmasphere. Nominal voltage in the US is 120VAC ±5 percent, so anything between 114VAC and 126VAC is normal. That is established by ANSI C84.1 standard.
Note that the spec is measured at the service entrance - it’s common to have some voltage drop at the AC receptacle. That’s something dedicated lines can help limit.
