How do you free up a seized pool pump?
How do you free up a seized pool pump? A seized motor will try to start, making a humming or buzzing sound, and eventually, usually, trip the breaker. The solution is to get a wrench on the back of the shaft, under the centrifugal switch, and repeatedly move the shaft back and forth to break the rust bond. It sometimes takes 5-10 minutes to free it up.
