Changed the pumps (2) and put everything back together- noticed blinking light. Prior to changing pumps was having issues with hot top popping breakers. Read bunch of forums ordered mother board and replaced. Replaced heater relay board 2 yrs ago still looks good. Replaced thermostats after noticing some burn marks. When I turned on the power worked for a little bit , than when I pressed the pump switch on main control. The pump worked for a few seconds , pressed the other pump switch and system shut down and power light began blinking. So now the only thing I have not replaced is the circulating pump. My question is how do you test the circulating pump and if this circulating pump was bad could it cause all the above. I called a repair guy he wants 200 dollars just to come out , not do anything
