Yesterday my polaris pool pump stopped working. It is wired to a timer . The timer appeared to stop working ( it would keep time) I replaced the timer today. No change. thought maybe the pump was bad. replaced the pump with a new pump. It did not work I have 120v going to the pump. The timer is still not working. The switch is on. Any thoughts? could the new pump be bad? I am having a hard time trying to figure out why the timer isn't working. I believe that is the problem. But I also don't understand why the pump isn't running with power to it>
