The service light stays on for the Guardian Plus GSFH1K when the filter maintenance indicator is triggered. This happens when it is time to perform maintenance, specifically when the Filter Maintenance light remains ON. It indicates that the HEPA filter cartridge, including the prefilter, needs to be replaced as part of the required annual maintenance.
