My pool pump fuse keeps blowing
I have a 240V pool pump that runs fine for about five minutes, then blows the fuse. I have already replaced the fuse twice, but the same thing keeps happening.
I checked the voltage at the panel, and it reads fine. The pump also does not make any unusual sounds while running. I have been looking for replacement fuses on Amazon, Alibaba, and eBay. The original fuse is a 20-amp slow-blow cartridge type. Since I am currently on a tight budget, I am buying more affordable fuses for now.
Could the issue be caused by a bad capacitor, or maybe a loose fuse holder creating excess heat?
