Basically the occurrences were the occasional dimming of lights around the machine, but it would come and go and happened inconsistently. This was 3-4 years ago, so I honestly cant remember everything. I do remember it happened over a few weeks before the soft start finally died out.

Blower is not throttled in any way, basically setup as regenerative with heating elements in its loop.
