Zodiac PB4-60Q Polaris Halcyon Booster Pump - Humming, but won't start

[Rigwald]

Yes, it's another one of those posts. My booster pump hums and shuts off. I've replaced the capacitor. I've taken off the back access cover and the shaft turns easily. Even tried spinning it fast as we turned on the power (as per a YouTube video suggestion).

Prior to it stopping working, if it was on for a while it would turn itself off and then come on on it's own. I figured it was due to overheating and we have had a hot summer.

Any suggestions on more troubleshooting steps to try?

Thanks in advance!

Unfortunately, the best thing you could do would be to get a new booster pump. Fewer and fewer parts are available and the pump hasn't been made for many years. A new PB4 - 60 pump, complete with new hose kit, can be found for slightly more than the motor on the Halcyon if you can find that motor (they're listed as obsolete on many sites).
