7095 stopped pulsing

[freddyg2]

I just noticed that my 7095 stopped pulsing. It is still switching between channels but not pulsing. Any ideas what to do?
Thanks....Fred

I tried the pumps with their 7091 controllers and they pulse.

If nightmode is on and the photocell is in darkness, pulsing will stop.

Oops! The sensor had moved out of the light. Thanks Roger!

I have another question for you please. Why is my 6100 making a low humming sound when it is at minimum power? I recently cleaned it according to your sticky and now it is humming. Could the drive unit need to be replaced?

It could be, but some noise after cleaning is not unusual due to air in the pump and parts resettling, I would wait a few days. Another thing to try is rotating the bushing 3000.620 180 degrees, it can insert in two positions and sometimes it wore one way and you move it and it throws off the alignment. It just makes noise but won't cause any real harm.
