Why Does HD90 Make My House Lights Flicker?

Back to List

Installed new HD90 two weeks ago.  Since then my table lamps flicker each time the dehumidifier turns on.   Dehumidifier is on a 15A GFI circuit shared by the table lamps.

Answers

When the dehumidifier starts, the compressor has an inrush current (1.5-2 times that of regular operation), which leads to the insufficient current of other appliances on the same line, so the lamp flickers. It is a normal phenomenon.

Why is the startup capacitor not sufficient to handle the inrush?

Hi, Rich! Sorry for the late reply. We think the lamp is not designed to deal with inrush current. The dehumidifying capacitor is fully capable of doing the job.
