To Next PageTo Next PageWhy is my Delta VFB080D4H1 so loud?
Your Delta Fan might be louder than expected due to several reasons. Ensure the CFM rating matches your room size. Check the damper for proper function; if damaged, contact Customer Service. Avoid sharp duct bends closer than 18 inches to the fan discharge. Use the recommended ducting size to reduce noise. Also, make sure the fan body is securely attached to your ceiling joists.
What to do if my Delta VFB080D4H1 is not turning on?
If your Delta Fan isn't turning on, first, ensure the power supply is on. If it is on, test or replace the switch. Also, check the wiring in the switch box.
What to do if Delta Fan is not clearing the room?
If your Delta Fan isn't effectively clearing the room, ensure a door or window is slightly ajar or opened to allow airflow within the room. Also, be sure the CFM rating on the fan matches the requirements for your room size.
Why does my Delta VFB080D4H1 Fan keep running?
Your Delta Fan might continue running because the sensor tolerance is +/-10% RH, so it's good to keep venting the house, and the electrical cost is minimal. Alternatively, outdoor humidity might be back-drafting into the fan; in this case, turn the fan off when not in use. Also, indoor temperature level can cause the fan to keep running.
