Maxxus
Sundance Maxxus has one source-verified record in SpaPartMatch: 6600-781, the Sundance 880 3-Pump 60Hz Control Board, documented for 2016–2018 as a service replacement. Its publication status is CONDITIONAL FIT. A service-replacement record states what the reviewed source documents as a replacement today; it is not proof of original factory installation.
SOURCE-VERIFIED REFERENCE — This page is built only from records that passed the source-verification gate. A record marked CONDITIONAL FIT still requires the exact configuration checks shown on that record.
