View Full Version : circuit board?

I have balboa vkv500 circuit - control board. Motor keeps turning on and off and sound like it's locked. I have checked motor and seems to be fine. Is it control - circuit problem? Thanks for any pointers.
ps Tried to post earlier but first post doesn't show up on the board. If this is double post I do appologise.

So this has a remote panel? Try disconnecting that first and try to run pump with main topside panel. If still doing the same it very well could be the circuit board causing it.

OK, this make no sense to me: on circuit board there is no black or burn marks. Part I don't understand is voltage output to the motor pump. My understanding is that output voltage for motor pump should be as follows:
between red and black = 240
between white and black = 120
between white and red = 120
What I am getting is:
between white and red =240
between white and black = 240
between green and white = 120
between green and black = 120
between green and red = 120
No one switch phases at a main panel and I can't see hydro co. switched phases cuz it would affect everything.
