Safety: Power off before removing the front cover.

1. Check tubing: Ensure the silicone tubes are connected to the correct ports on the Ferroli air pressure switch and are not kinked or blocked.
2. Clear moisture: If water is present in the tubes, drain and dry them. Investigate condensate issues.
3. Replace switch: If the switch does not change state when the fan runs (technician test), replace it with the correct Ferroli pressure switch.
