Troubleshooting a Pool Pump Motor

My pool is not turning on at all. The timer works but when I do the manual switch it doesn’t turn on.

Good for a small/medium room.Gets pretty hot so watch out witb objects neat it

Thank you! Very helpful!!

We need to address symptoms. I have a diagnosis problem because my switch controlled by the clock does not work. I replaced the clock, ($60) still doesn't work. Have full 220 power. switch does not start the system, but clock still doesn't run. I don't know if the motor would start if that switch isn't getting power. Is this a transformer problem? No power to the Transformer detected.

Where is the video you mentioned on testing the pool
pump capacitor? I don't see it on your channel. Thanks.

My timer is not working

Am I supposed to be reading 240 between both hots?

another thing that could cause the motor not to run or run poorly is the START SWITCH at the back end of the motor. You should see 2 brass arms (or more) with contact points that should be touching when the motor is off. This goes to the start winding. Once the motor starts turning fast enough, there is mechanism on the shaft that relys on centrifical force to push something, usually a plastic or bakelite piece against the arm to open the START winding circut and the motor then operates on the RUN winding. If these contacts have debris between them, the motor will likely not start and just hum. If these contacts remain stuck together once the motor is running, it will cause the START winding to stay engaged and put a negative force on the armature, causing it not to spin up to speed.

I'm fighting a breaker issue right now. The old pump was seized, so I bought a new pump. Now it's tripping the breaker. Tried several breakers, 15, 20, and a 40. Trips instantly no hum or anything.

Fixed - replaced the capacitor last week and it worked fine. Now it stopped working again. Could the capacitor have gone bad so quickly? Or do I have bigger pronblems?

Richard, you saved me $2000. A wire came off at my timer. And I attached it to the first post on the left. It seemed like that’s where it belonged. After the pump wouldn’t start, I watched your video again, and realized it had to go to the second leg where it shares a place with the white wire. Fired right up! Bless you, buddy!

if the motor to the timer stops working would the manual switch work regardless? My timer stopped and when I switch it on manually the pump doesnt turn on. my 240 breaker also flipped. checked breaker. still have 240 reading both at breaker box and at timer junction box. would anything malfunction with the timer cause my pool pump to not work, or does this sound like a pool pump issue?

Mine has 240 going to the motor. This is the second brand new motor that I’ve put on, I thought the first motor may have been bad. Neither motor did anything. Any thoughts?

If you use a clamp on annmeter around the main power conduit would you see if the motor is under strain?

Just replaced seals on diverter switch due to air leak and not easily getting prime. Our pump works better than ever. Perfectly sealed no more air. BUT the switch is turning the pump on only intermittently. Have to click it and click it to start the pump. Capacitor? Or bad connection?

This saved me! I just changed 2 capacitors turns out the shaft is tuck. I just turned it to move it and it worked! Thank u!

Brand new sand pump… motor doesn’t come on…any suggestions?

Will that thick stiff ground wire that clips to the back of the motor affect the pool pump as well? Or is it just for lightning ⚡ storms?
