PE6U21 makes a crackling/bubbling noise when first energized
I have a APC SurgeArrest Essential Multi-Use. In recent months (probably nearing a year now), it has been making crackling noises when the I turn it on. Is this normal. Please note, this is not a UPS and these are not UPS buzzing noises. This is more of a crackling/bubbling noise.
