How to Fix / Troubleshooting
Safety: Turn off power before inspecting ducts or blower.
- Replace filter: Always start with a clean filter.
- Check registers and dampers: Ensure all supply registers are open and that any manual dampers in the ductwork are not closed.
- Inspect accessible ducts: In attics or basements, look for crushed or disconnected flex ducts connected to the Luxaire plenum.
- Blower speed: If the blower seems slow, a technician may need to adjust speed taps or ECM settings, or replace a weak motor or capacitor.
