First time poster looking for some advice here. I'm pretty handy around the house and wanted to take a crack at repairing my pool pump / motor. It has stopped running for well over a month now and whenever I reset the house breaker and turn it on, it flips the breaker in the main house electrical panel as soon as it starts to run. One time I observed a large "WHOOMP" sound and a small flash from inside the motor housing as it happened.
I'm assuming something is causing it to short the circuit and am looking for advice on how to diagnose and/or fix.
The set up -
Live in Dallas, TX (and praying the recent ice didn't freeze anything beyond repair - pump stopped working before this...)
In ground pool - approx 14k gals
pump is Century Centurion with 2 HP A.O. Smith (approx. 3 years old)
Thanks in advance for any help.
