If you have a whole house fan, then you know just how beneficial it is to your home and family. But, this great investment is not without its problems now and then. Like all appliances, your whole house fan is bound to experience issues eventually. The good news is, most problems are very easy to fix if you catch them early.

We are highlighting three of the most common problems that we see with whole house fans. Keep reading to learn more about how you can identify problems early and address them before your whole house fan breaks down completely. If you notice any of these signs, give us a call for whole house fan repair in Vineland, NJ.

Damaged Motor

If it seems like your whole house fan is not working quite as well as it used to, there may be a problem with the motor. You may also find that your whole house fan is not turning on at all. Usually, you’ll begin to hear unusual sounds before your whole house fan breaks down completely. Don’t ignore allowed or unusual. Sounds coming from your whole house fan, because the sounds always indicate that something is wrong. 

The most common causes of motor problems are loose wires, bent fan blades, or a lack of lubrication around bearings. These problems can be silent at first and not show any warning signs until there is already damage. That’s why annual AC maintenance is so important. When you schedule annual maintenance for your air conditioner, we can also look at your whole house fan and check each of these components to make sure they are in good working order. 


It’s also possible for your fan to overheat since it has a motor for operation. If your fan starts to overheat it can trigger a safety reaction where your fan turns off to prevent any damage and fire hazards. If your fan is shutting off frequently without explanation, that is a sign of the system overheating. This is usually due to poor air circulation because of an air blockage or ventilation issue. 

Broken Thermostat 

Many homeowners don’t realize that their whole house fan has a thermostat attached. This is how your whole house fan knows when to turn on and off to circulate air. The thermostat also helps to regulate the temperature of the fan as it is operating to prevent overheating. If your thermostat is not working correctly, your fan may not turn on and off when it should, and may also be more prone to overheating. 

Sometimes fixing your thermostat is as easy as recalibrating it or changing the batteries. It’s also possible for your thermostat to get dust and dirt on the inside that impact how well it can operate. No matter what the problem is, our team can troubleshoot and get your thermostat working again. If none of these solutions work, we can replace it.
