Both pumps noted in the title are basically identical. But nothing sets the tone on a hot TX August day than to find low speed no longer works after running the pump on high for a while to do some cleaning and chemicals. High speed yes, low - dead. Bummer! :brickwall:

Fortunately I had ordered new capacitors (start & run) months ago preparing for such an event. I had some subtle signs of starting issues the past year or two, and my motor was made in 2014, so it's no surprise. After removing the rear motor and top hump covers, I replaced both caps and was back in business in a matter of minutes. Nice to have some extra parts available. Now, back to the water. :swim:

So my question now is for @JamesW. A week after replacing both caps on my motor, the low speed stopped working again this evening. High works. Either I'm unlucky to get bad caps, or could it be a thermal switch issue in this motor? Is it worth trying to repair before scrapping the motor or pump? Motor about 7 years old.

So first I thought it was the capacitors since the motor worked fine for a week after replacing them. But a week later totally dead. I ordered a replacement pump, but while waiting decided to tear apart this pump in preparation for replacing the motor and keeping it as a spare. So what did I find? A short on the wire seen below. What speed wire? .... low speed of course.

So I cleaned everything up, replaced the broken (short) wire, and did some pad maintenance while I was at it. We're bac in business baby!
