Mine at present having issues: The vent pumping over when the motor is set in either 2 or 3.

Would you mind answering?

Q1: I hope my installer will help us out.
Q2: No
Q3: No,It comes on at 5.30 a.m and hence causing an issue,I suppose. The noise is very obvious though.
Does it matter that the Motor could not run on 3?

Thank you
