    What to do if my Delta Fan is not turning on?
    • T
      Terri BarnesAug 9, 2025
      If your Delta Fan isn't turning on, there could be a few reasons. First, ensure that the power supply is switched on. If the power is on, the problem might be a faulty switch, in which case you should test or replace the switch. Another potential cause is a faulty wire connection, so check the wiring in the switch box.

    Why is my Delta Fan so loud?
    • H
      Hannah LopezAug 15, 2025
      There are several reasons why your Delta Fan might be louder than expected. First, make sure the CFM rating on the fan matches the size of your room. Second, inspect the damper to ensure it’s opening and closing correctly; if damaged, contact Customer Service. Third, ensure there are no sharp bends in the duct closer than 18 inches to the fan discharge. Fourth, use the recommended ducting size to reduce noise if the fan discharge has been reduced to fit a smaller duct. Finally, ensure the fan body is securely attached to your ceiling joists.

    What to do if Delta breez VFB25AEH is not clearing the room?

      Kenneth WalkerAug 21, 2025
      If your Delta Fan isn't effectively clearing the room, it could be due to: * Insufficient intake airflow. Ensure a door or window is slightly ajar or open to allow airflow, as the fan needs sufficient airflow to draw air out of the room. * Insufficient CFM. Verify that the CFM rating of the fan matches the requirements for your room size.

    Why does my Delta breez VFB25AEH keep running?
    • S
      Scott SchroederAug 27, 2025
      Your Delta Fan might continue running even when the house humidity is lower than the set level for a couple of reasons: 1. The sensor tolerance is +/-10% RH. It's good to keep venting the house, and the electrical cost is minimal (approximately less than $10 per year). 2. Outdoor humidity might be back drafting to the fan. In this case, turn the fan off when not in use.
