Don't know nuttin about your pump, but that is a lovely pond at sunset. A pond that makes most other pond owners jealous!

SWAG: Your motor winding are burned up. The motor would have to be replaced. It is not cost effective to have it re-wound. I would bite the bullet & buy a whole new unit. How old is it? Also a low amp fuse that will blow before the motor is damaged?

If I am ever in Graham County, can I stop by & sit by your pond at sunset?

Glad to have you back with us at Pond Boss.
