In this case shut off the power to the fan and check the blades. Here is some information so you can decide whether an attic fan is right for your home. The main work of an attic fan is to regulate the heat level of the attic by removing hot air out of the attic and pushing it outside providing needed ventilation. Poor insulation is usually the culprit although if you enter the attic on sunny winter day your attic space can be warmed by the sun more than your furnace.

A central air conditioner is an elaborate system that involves parts such as an evaporator a compressor a condenser fans and refrigerant to run through the unit. Manufacturers of attic fans as well as hvac companies will tell you otherwise. Little or no airflow. Unless your roofing system has insulation on the roofing deck and is designed without ventilation your furnace should not be heating your attic.

Energy professionals will tell you that they do more harm than good. Strong attic fans can actually back draft furnaces or water heaters by pulling combustion gases out of their burnersand into the home. This issue can happen on any type of attic fan as it is caused by the fan blades being bent dented or broken. Look at the circuit breaker or fuse box to see if a switch has flipped.

Check that a whole house fan is receiving electrical power when it doesn t work at all. If the motor is working but the fan blades are not moving the problem may be the belt.

Whether or not an attic fan really works is a controversial subject.

Remove the outer casing of the attic fan and check to see if the belt is sagging cracked worn or broken. You can diagnose it by plugging other electrical appliances that are working into the same outlet and by plugging the fan into a different power outlet.

Attic fans come with different models. If there is any damage to the belt replace it with a new one. Some can have manual switches while others use a thermostat to turn them on and off automatically. If this doesn t fix the problem a burned out fan motor may need replacing.

If you notice that the ventilation from the attic fan is not flowing as well as it should be there might be a blade caught somewhere. Switch off the power of the attic fan and remove the power cord. Fan motor runs but not the blades. Like many household appliances each of these components does their job both independently but also in unison with the connecting.

If you notice that the attic fan is not switching on or off according to temperature variation it indicates that the thermostat is no longer functioning properly.
