AO Smith, now sold under the Century brand, manufactures the replacement motor inside most pool pump repairs. When a Hayward, Pentair, Jandy, or Sta-Rite motor burns out, the replacement is often an AO Smith or Century motor — making this one of the most purchased pool motor brands even though it rarely appears on original pump installations.

This section covers AO Smith and Century motor selection, compatibility cross-references for major pump brands, installation steps, and troubleshooting issues specific to replacement motor installations.
