My Attic Turbines Are Not Turning

Attic turbines will help to keep moisture from inside the roof.

The spinning turbines pull warm air from the attic more quickly. But if turbines won't spin the effectiveness of your ventilation system decreases. You can fix turbines in a number of ways.

1. Climb up into your attic and look at the vents from the inside. If the vents are blocked by insulation, boxes or other obstructions, heat will not be able to escape through them and they will not spin. Clear away any debris or insulation blocking the vents to re-activate the spinning turbine.

2. Examine the turbine from the exterior, from the roof. A turbine may fail to spin if the bearings become rusty or obstructions such as ice, leaves or twigs have become wedged into the turbine.

3. Clear any obstructions away from the turbines by pulling them free.

4. Treat bearings by spraying the pivot point with WD-40 spray. The spray solvent will loosen rust and free the bearings.

5. Spray silicone lubricant spray onto the pivot point to grease the mechanism.
