Sometimes it's a bad motor.
Please Check this first though....
Sometimes it's simply the fact that the motor is starved for current or
amperage. Amperage requirements on the motor of the pump are
typically on the nameplate of the motor and may be listed as FLA which stands for "full
load amps" should be
checked against amperage supplied to the unit by the electrical service
box (check the breaker). Many times we have
seen a situation where the pump won't start or the motor is clicking and
it is simply, there is not enough amperage being supplied to the
pump. Try plugging the pump into an outlet where you know the
amperage is right and plentiful (20amp). If it works then you need
to up size the breaker in the breaker box or take some things off that line
so that the pump gets enough current to run. Make sure you have
a decent extension cord engaged if you are using one. Too "lightweight"
an extension cord can cause the same problem, not usually, but sometimes.
We ask you to isolate the pump to a good circuit...... as if you have a
circuit with a freezer hanging off it, and a PC over here and lah de dah
de dah then we are not really giving it a chance. Please arrange a
fully amped power source to test the pump before we go shipping pumps
around the country. Again we have already been there, done that and
freight today is expensive.
If there are still problems with the pump the chances are good the
motor is not functioning correctly. Many of the fractional motors
now come from other countries. They are not made in the USA and we
have seen widely varying quality levels in this area. We see a lot
of motors at the factory and we do see a fair amount of junk. ( Must
be all that ISO 9000 stuff, since all our vendors in this area are rated as
We just got in 10 motors and 1 failed, 30 motors and 1 DOA.
That kind of stuff is not uncommon here. We sincerely try and we
test them first out of the box, then hooked up to the end pump but still
they get away from us. We apologize we have tried all we reasonably
