What causes low voltage at outlet?
Low voltage from household outlets typically stems from a worn-out or damaged fixture. Over years of use, outlets sustain wear and tear just like other frequently used items. Over time, plugging and unplugging cords causes the connections within the plug to loosen, which wears away the outlet.
Will high voltage damage appliances?
If the voltage is too low, the amperage increases, which may result in the components melting down or causing the appliance to malfunction. If the voltage is too high, this will cause appliances to run ‘too fast and too high’ which will shorten their service life.
Why would half an outlet stop working?

This is particularly common in older homes, that may have at one point been rewired or had the outlets replaced.
Why would a GFI make a buzzing sound?
GFCI wall outlets require good connections to the electrical system (wires). Loose wires cause unpredictable results. Loud buzzing is caused when the GFCI trip mechanism oscillates. Power conditioners and surge protectors can cause unpredictable operation of GFCI devices, INCLUDING BUZZING.
What does electrical buzzing sound like?
Fun fact: In the United States, our standard power is 60 hertz, and mains hum sounds like a B-flat. But in Europe, power is 50 hertz, so mains hum sounds more like a G. While mains hum can be annoying, it’s not dangerous.
Why is my plug making a crackling noise?

One of the main causes of cracking and popping noises that seem to occur randomly in a house, mainly deep within the walls, floors, and ceilings, is known as thermal expansion. This same phenomenon is responsible for many other inconsistencies house-wide, particularly around door jambs and window frames.
