This morning as the storms rolled through and I was getting ready for work, we had a few brownouts. Pretty hefty voltage sags, popped 3 or 4 GFCI's, and ... apparently killed my pump motor. I didn't notice it when I left, but when I get home the pump is usually running at low speed and there was no water moving. Went out to the pad and nothing. Put the panel in service mode, turned off the pump, and put my hand to it - quite hot to the touch. Let it cool down for an hour, and tried to power it back up. Loud hum, no movement. Figured start capacitor, but tested it and nope - dead on 35uF. Popped the lid and stuck my finger in the impeller, and was able to easily spin it freely, so no clog and the bearings are good. Pulled the motor off the pump and brought it to the bench, pulled the back cover and found a nice scorched section of the windings. Drat.
I'm guessing there's not much left to do but replace the motor, right? FWIW it's a Century 2.5HP 2 speed motor on a Hayward pump, SP1620Z2MC / 7-184874-01
