Just replaced the capacitor,started the pump, water running in the skimmer, checked to be sure the shaft was turning freely and it is, then smoke was coming out the back! I have made sure the impeller was clear of all debri as well...HELP

Most likely the run capacitor yes. Some motors have 2 capacitors, some one, some a combined start/run capacitor.

Replace it with one the same or greater voltage, and the same capacitance.

Check the start switch inside the motor. I.e the spring and fly-weights to make sure they slide on the armature shaft. If this is stuck in the run position (away from the start switch) it will not allow the capacitor to start the pump. If it does move freely the most probable suspect is the start capacitor. Since I am responding in generic form without a model number this imfromation is fitting to the majority of pump motors.

With the breaker for the pump off, Remove the spindle cover at the back of the motor and make sure it spins freely. If it wont move then the pump will have to be taken apart to see what is obstructing it.

If it does spin, then replace the capacitor mounted on top of the motor itself. This can shock the bejeezes out of you so make sure the breaker to the motor has been off for several minutes and be careful! They cost about $20.

If this does not solve your problem than its time for a new motor!

Check the weir door in the skimmer. If it gets something in it to stick it in the up position you will get water trying to run into the skimmer but with the door stuck shut the water get's pulled out by the pump and can't refill the skimmer fast enough. So the pump runs out of water then the skimmer refills. The pump will catch prime and run the cycle again and again. Free up the skimmer weir door and this will fix this. Also low water will do the same thing, so be sure you have enough water in the pool.

there may be a shard of broken glass stuck in the wash pump, this is very common. or it may be the capacitor that has worn out. try gaining access to the wash pump and with a slotted screw driver, turn the shaft at the back of the motor, if it turns freely, with EXTREME CAUTION, start the machine up and when the motor should be running, turn the shaft with the flat screw driver and if it runs as normal, replace the capacitor, that will solve your problem. If on the other hand the motor is jammed when you initialy turned the shat, there will be glass or something similar stuck in it. hope this has been beneficial to you.

sounds like you have a bad start capacitor, check that first and make sure the motor spins freely. You may be able to check to see if the motor is seized by removing the end cap and spinning the shaft. If it spins freely, it's a bad start/run capacitor.

Check to be sure water level is up where it belongs then check to be sure your skimmer weir door is free. If this is stuck water in the skimmer will run the pump for a moment then the water will run around the door and fill the skimmer to start the cycle again.

A humming motor usually means a bad starting capacitor, but it could be some other things. If you see some water movement that means that your impeller is spinning and the capacitor is good, and in this case you would want to check for air leaks on the suction side of the pump. Make sure that there is water at least 3/4 of the way up in the pump and the valves are in the right position (sometimes turning the skimmer off and just sucking from the main drain can help). Also check to make sure that there is water in the skimmer, and it is not getting sucked dry. Next lubricate the pump lid gasket, and try some silicone around the threaded pipe on the front of the pump. If all this fails you could have some debris stuck in the impeller.
