I have an Aprilaire 400 connected to my HVAC/forced air heating unit which doesn't seem to be working. I've tried the following:
- Followed instructions from Aprilaire to test/check the humidistat. I hear the clicks, but don't see any water coming out.
- Changed the water panel, however the humidistat 'change water panel' light is still on (see attached picture)
- checked the water pipes and pump but see no obvious problems.
I live in Long Island NY, and the inside humidity is 25% irrespective of the outside humidity.
It'll be great if any DIY experts can let me know if I can do anything else before calling a professional to look at it.
