Hayward Pump motor, hums but won't start. If I turn the shaft it will keep running but once I turn if off it will not run until I do the same thing again. I have replaced the capacitor but still the same problem. I have a hayward 7-193347-01 1.5 - 1.6 hp motor/ SP1514Z2S4EC
1 or 2 capacitors on this motor?
Sometimes there are two...
One is a "Start" capacitor and if a 2nd one, that one is a "Run" capacitor.
If only 1 capacitor and you have replaced it... if not a faulty capacitor, then your windings are shot?
When I test a motor with this symptom, I will use the "Clock Face" method of checking for "Dead Spots" on the winding/stator:
Once you have removed the shaft cap on the back of the motor, I presume you have done this since that is only way to turn the shaft manually to get it to run in the manner you described. Place a small mark (1/4" long?) on the outside perimeter of the shaft, say at the 12:00 position. See picture attached...
Then flip switch, does it start or hum?
Then rotate shaft until your mark is now at the 1:00 position. Flip power switch, running or humming?
Do this at all clock positions as you turn/rotate shaft until you reach 12:00 once more. If the pump hums at all clock positions completely dead motor or bad capacitor. If a dead spot is at only one clock position, then absolutely, bad motor - either rebuild or replace.
Coincidentally the motor may stop each time on a dead spot, where the motor won't start due to a fried portion of the stator/winding/armature, only a major repair fixes this. The purpose of the test is to place the position of the stator in a different position in relation to the windings. If humming all the way around, then possibly a bad capacitor, because it is not starting in any position. If it starts say at all positions except 4:00 and 9:00 then motor is bad.
Good luck
Did you find the correct capacitor?
did you check the ball bearings,maybe there are rusted and now you have the coils in bad condition,that is the reason your motor Humming and no starting.when a coil is over heated the motor does not starts and Humms
SOURCE: Hayward 1 hp super Pump just hums then shuts off.
turn shaft manually wiyh pliers if somthing is stuck in propeller this should clear it
SOURCE: my hayward pool pump started making a humming
check impeller by turning shaft with pliers sounds as if its stuck do this while of and try to restart
SOURCE: The pump only hums when plugged in. Any suggestions?
It sounds like the impellor is locked. Take this part off and then see if the pump is turning but before you do, some of them have a big screw driver slot in the shaft. If it does, turn it to see if you can free the impellor. I have done this many times and they will continue to work for years after. They just get stuck from rust, etc. and also being frozen a little. Hope this helps.
SOURCE: I have a hayward 2hp pool pump motor that hums but
your starter capastor has gone bad or got diconnected it`s look`s like round cylender 2 inch by 4 inch dimention`s or it could be an internal (inside the motor) depending how new the motor is
Testimonial: "Thank you very much for your help"
SOURCE: I have a Hayward power
Jay, to be honest, with all the time your gonna spend searching and trouble shooting the pool is going to turn green and then your going to be stuck with bigger problems. The powerflo pump is a pretty inexpensive pump. Personally id just swap the pump and get it going so the pool stays clear.
Over the winter,tinker with the bad pump and see if you can fix it. If not, trash it. If you can fix it save it for a spare or sell it for 75$ on craigs list and make half your money back you spent on the new one.
