Just wondering if having both low and high speed leads hot at the same time will damage the pump motor?
I have a Ao Smith motor pf-30-2n226 3 hp motor and a partly failed spa controller.
When the pump is connected to the pump one connector, the pump only operates on high speed, the low speed circuit has failed.
I can connect the pump to an aux connector and operate the pump normally.
I was thinking to avoid a hefty repair bill (ie replace the controller board) that I could split the low and high speeds connections across the different connectors.
So when the controller calls for circulation, the pump connector is hot, when I want full speed I preass abutton and the high speed line becomes active.
The problem with this is it would be possible to cause power to energize both high and low speed lines at the same time. I need to find out if this will damage the pump motor or not?
