Read on to learn how to tell if your AC is malfunctioning due to a blown fuse.
How do I know if my AC fuse is blown?
If you think that your air conditioning unit may have blown a fuse, your best course of action should be to consult professionals, especially if this is not the first time this has happened. You can tell if your fuse is blown by checking the outdoor unit. If the unit isn’t doing anything except producing a slight humming sound despite having no power, you may have a blown fuse on your hands.
Why does my AC fuse keep blowing?
There are a multitude of reasons why your air conditioner may be blowing fuses. A blown fuse is a symptom of an underlying mechanical and/or electrical issue with your A/C system. Continuing to replace a fuse without identifying and repairing the core problem will result in complete failure of major system components. What should have been a minor repair such as a loose wire connection can quickly manifest into major repair such as a failed compressor. The difference is hundreds of dollars in repairs versus thousands of dollars in repairs. This scenario is very common
Here are some of the most common culprits:
Clogged or dirty filters can cause a wide array of issues with your air conditioner. During very hot weather, your AC unit will work harder to cool down your home, which can lead to a blown fuse if your filters are dirty to boot. The extra pressure that is put on the AC to blow the air through the clogged filter may easily overwhelm the electrical system, leading to tripped circuit breakers or blown fuses.
Your AC may have blown a fuse because of loose wire connections. Loose wiring connections can exist from your breaker box to multiple component terminations within your A/C system. The wiring will contract and expand, they can become loose over time, compromising the safety of the system. These circuits are high voltage and may result in injury or death. Any diagnosis and repairs should be performed by a qualified HVAC professional.
The capacitor of your air conditioning unit is a component designed to regulate electrical flow to your system’s compressor and condenser fan motor. If your capacitor is malfunctioning, it can easily cause your AC to keep blowing fuses. Capacitors should be tested and replaced by a trained service professional.
Malfunctioning condenser fan
The condenser fan of your air conditioner blows air over the condenser coils of the system. If it’s faulty, your air conditioner won’t be effective at cooling down your home, and may blow a fuse or two if it has to work too hard.
Low levels of refrigerant in your air conditioner will force the system to work much harder in order to maintain optimal performance. Blown fuses are a possibility if your AC unit continually overworks itself.
How long do air conditioner fuses last?
The average AC fuse can last the life of your system.
However, a number of underlying issues with your AC can speed up the rate at which the fuse wears down. If you notice that your air conditioner is experiencing electrical issues, don’t waste time trying to diagnose the exact problem yourself, as this may lead to serious damage to your property as well as your AC system.
