Attic FAN Troubleshooting Before calling an expert
We are often burdened with expensive repairs every time an appliance breaks down. And such is the case with an attic fan. However, is it entirely necessary to call an expert? What if you could fix the fan on your own without draining your pockets?
We say this due to the several faults that may appear in an attic fan that the user can solve independently. Therefore, there isn’t always a need to call a professional who will only hand you a hefty bill, especially when the fault is minor.
Importance of Attic Fans
Before getting down to some of the common faults, let’s shed light on what an attic fan is and why it is an essential appliance to maintain. Attic fans are situated on top of households, specifically their roofs, to help control the temperature. Since warm air gets to the top-level surface, fans force it out and pull in fresh air to cool the house down.
Reasons to Maintain an Attic Fan
Users with attic fans installed can save a significant chunk on electricity charges by avoiding the constant use of air conditioning systems when the temperature isn’t quite so hot. A defective fan can be costly to maintain, but it will save you money in the long run by lowering your power costs. This is why you must spend ample time preserving these ideal appliances.
Basic Attic Fan Faults and their Fixes:
You’re undoubtedly acquainted with the issues that your attic fan causes. However, understanding the right way of diagnosing and troubleshooting a problem might save you money by allowing you to fix the minor issues without having to hire a professional.
The most frequent issues householders have with attic fans are listed in the following paragraphs, so read ahead! We’ve also listed down the most appropriate solutions to these problems.
Attic Fan Stopped Working
If you have an attic fan not working or turning on, it might be due to a thermostat malfunction, an electrical fault, or broken fan motors.
1. Thermostat MalfunctionTurn the fan on and off without using the thermostat if your fan has one. If the fan turns on, the issue is most likely with the thermostat installed in the fan. The expense of thermostat repairs is determined by the root of the attic fan malfunction. It is frequently more cost-effective to change the attic fan thermostat than to fix it.
2. A Problem With Electricity
Any electrical fault, such as a blown fuse box, a poor connection, or a blown circuit, might be preventing the attic fan from switching on. Trying to plug different electrical equipment into the same outlet and the fan into a separate power outlet might help you figure out what’s wrong.
If the circuit and fuse breakers are fine and none of the other outlets are functioning, there might be an issue with the fan that requires a specialist to examine.
3. Broken Fan MotorsThe most costly fix for attic exhaust fans is indeed the attic fan motor. When you determine it’s neither a thermostat nor an electrical fault, the odds of the problem being motor-related increase significantly. You’ll need an attic fan motor upgrade or an attic replacement fan if the motor stops operating.
Attic fan humming noises
The most common reason behind repetitive or constant humming sounds from your attic fan is the number of blades operating at a higher speed. A noisy attic fan is not a nice ring to the ears, and the ideal solution to this fault is installing a newer attic fan model with more blades.
An easy fix that might work is running the fan at a lower speed setting, helping reduce attic fan noise. However, keep in mind that if you opt to get it replaced, you must test the attic fan in the shop to listen to its sound so that you are aware beforehand.
The Fan Motor Works, But The Blades Do Not Move
Another common issue that users may face is the blades of the attic fans remaining stagnant, even though the motor is functioning appropriately. The majority of times, the primary cause behind this issue is a broken belt, and to check whether this is the case, you must open the fan’s exterior casing and check whether it’s broken, cracked, worn out, or drooping. If such is the case, repair the attic fan by installing a new belt.
Airflow is Almost Non Existent
If your attic fan is producing little to no air, especially in a faster-paced setting, this might have something to do with the exhaust or intake mounted with the attic fan. The outcome may be a sluggish and slow-operating fan that is of no use. To fix this common problem, we recommend you check debris intake, clear it up if there is any, and ensure that the fan is mounted as close to the roof as possible.
Attic Fan Producing a Burning Smell
A fault that is more common than it seems is the attic fan creating a burning smell. The simple explanation behind this is a broken motor or a motor that is jammed up. To confirm the fault, you must open the fan’s casing and take a look at the engine – try oiling it and notice if the belt is intact or not. Next, try turning the fan on again; if the fault were repairable, then the smell would be gone. However, if the fan still produces a burning smell, you may have to replace the motor.
Attic Fan Making Screeching Noise
If you have an attic fan making rattling sounds, it is probably due to a suppressed air supply. This is another rudimentary issue that many house owners face, so it shouldn’t worry you too much if you meet the same problem. The easiest fix to this fault is by opening a window nearby (it should be at a distance of at least 30 feet, though) which can assist in ventilation and provide the required air for it to stop making noisy sounds.
Attic fans are very purposeful for the temperature maintenance benefits they offer, resulting in a lessened electricity bill, enabling you to save up. Several common issues may appear due to the constant use of these fans, but that doesn’t necessitate the need to call in a specialist who would charge hefty amounts to repair them.
Several common faults, such as an attic fan noise, attic fan vibration problem, a burning smell, and more, can be fixed with minor tweaks. However, it is always a good idea to try attic fan troubleshooting on your own before calling in a professional.
