I installed a 1.5hp Pentair Whisperflow today I got off c-list for $220. He replaced impeller and seals.
Anyway, I set the jumpers for low voltage to go with my 110v supply. Initially, it didn't want to turn but rather buzzed loudly. Drained the capacitor and tried again and it ran just fine for about 15 minuted and tripped my 20A breaker. I tested the Amperage and it is pulling 23Amps but the motor label shows 16A max. The capacitor is spiking at 300v initially and settles at 270v after startup. This seems wrong to me and I think it may explain why I am having the high amperage issue.
Anyway, are there any suggestions? Would a bad capacitor cause this? I ohmed the cap both directions and it did not charge and go open. I am just concerned if I change the cap, some other underlying issue will cause it to go bad.
How much do those caps go for?
