I've got a Marathon motor with thermal protection. It's a little over 4 years old with low use. It's been running fine, no strange bearing noises or hums. Today I turned it on at 9am. We were swimming this afternoon and it shut off at around 4pm. It's 100 degrees today.
I checked the breaker, that's fine. It simply does nothing. I'm thinking the thermal protection kicked in? Am I on the right track? Anyone know how long it takes to cool down?
