  1. I just installed my new Polaris booster pump PB4SQ about a week ago. It will run for about five minutes then cut itself off. I wired it up just as the instructions said. Is anyone else having this problem? I really need to get the problem solved. Thanks so much for any help.

  2. My pump ran fine for about 18 months. Now suddenly it will not turn on. Makes zero noise when the relay powers it up. I have 240V at the pump, wiring looks great, matches the Polaris manual exactly. I have replaced the capacitor. Pump & impeller both spin freely. I don’t know what else it could be.
