Response to Wondering if you can help. I have a Century 1.5 HP Square Flange 56Y Up Rate Motor - B2854 working on my pool and yesterday pump stopped working and was making a large humming sound. Shut it off and tried to restart after a short time and same thing happened. Tried again about a half hour later and it starting working. Today, I tried to turn it on and same issue (humming sound) but a few minutes alter it starting working again. Any idea what the problem is?
