Bryant AC Blowing Fuses [How to Fix]

An air conditioner is a powerful appliance that requires a lot of electrical energy. However, there may be electrical issues. Learn how to fix Bryant AC blowing fuses in this article.

Bryant AC Blowing Fuses – Fixed

The following are possible reasons your Bryant AC is blowing fuses and how to fix them:

1. Weak Electrical Connections

The circuit breaker that controls the air conditioner may have loose or weak connections. These connections affect how well the system works, and heavy loads may directly blow the fuses. The problem may stem from age, usage, or temperature issues. 

If the temperature is hot or cold, the wires can contract or expand, eventually damaging or causing them to become loose. Another possibility is that the house’s wiring cannot carry the air conditioner’s electrical load. 

This is especially true if it is an old house; the wiring may need an upgrade to prevent damage to the fuses in the breaker box. Therefore, have an electrician check the circuit breaker and other electrical connections that power the air conditioner to determine and fix the faults.

2. Defective Condenser Fan

The primary duty of a condenser fan is to blow air over the condenser coil to prevent overheating. Since the coil carries heat and transfers it out of the cooling system, keeping it from overheating is crucial to how well the system functions. Therefore, the fan must always run when the system is running a cycle to cool the coil as it dissipates heat. 

However, a defective fan cannot blow air over the coil, causing it to overheat over time and compromise cooling. Eventually, the compressor and other motors run harder to provide cool air, putting a strain on the fuses and causing them to blow. Inspect the fan to determine if it is defective. 

Ensure you turn off the disconnect switch next to the condenser outside the house before removing the grate to check the fan. If the blade is stiff, it may indicate worn motor bearings. Clean the fan and check the motor; test it with a multimeter to check for continuity. Replace the motor or the entire condenser fan assembly if you find no continuity.

3. Clogged Air Filter

Check the air filter if you find that the condenser fan is in good working condition. The filter is vital in delivering clean air into and out of the air conditioning system. But while the filter can hold a lot of contaminants, it eventually becomes too clogged to filter the air properly.

A significant amount of dirt on the filter restricts the airflow and causes cooling issues. The lack of air in the air conditioner triggers the system to work harder than usual to produce air, which wears out the compressor and other parts. As a result, they overheat, and the excess load affects the fuses and the breaker.

You may notice the air conditioner struggling to produce air or blowing too hard. Remove the filter and clean it if that is the case. However, replace the filter if it is too dirty or has been used for too long. Ensure you use filters compatible with your Bryant AC model and a high MERV for the best results.

4. Dirty Condenser

You should also check the condenser to see if it is dirty. The condenser is the outdoor unit where the coil, compressor, and fan operate. The dirt easily finds its way into the condenser due to its location outdoors. 

Therefore, cleaning it once or twice a year is crucial to the system’s functionality, especially if trees, leaves, or shrubs are around it. Use a vacuum cleaner to remove dust and debris. Sometimes, dirt may cake on it, and a vacuum can only do so much. In such a case, a garden hose is handy; set it to medium or low force before using it. 

Allowing the water to flow out with too much force can damage the fragile coil fins, which may mean replacing the outdoor unit. You also can use the services of a trained HVAC technician to clean the condenser coil, fan, compressor, and other components in the unit for a professional touch.

5. Faulty Blower

The blower is the fan in the indoor unit or furnace that circulates the air from the system. It blows air over the evaporator and moves the air around the house. However, the blower can become faulty; dirt may clog the blower wheel, or the motor may stop working. 

The reason may be due to a clogged air filter, poor usage, or wear from years of use. And if the blower does not work well, the air conditioner cannot produce enough air, which affects the system. It begins to overheat due to the excess work of maintaining a cool temperature, putting a load on the breaker, and blowing the fuses. 

Contact the Bryant Service Center to schedule service if you suspect the blower is faulty or needs a replacement. Alternatively, use an independent technician for the job.

6. Dead or Faulty Capacitor

This small component can make or mar the air conditioner’s functionality. It regulates how power flows to the compressor and fan motor and provides enough electrical power to keep them functioning. But while you do not have to replace the capacitor every few years, poor usage or age can cause damage or a malfunction. 

It is best to let a technician test and replace the capacitor if necessary. This is because the component stores power like a battery. It provides power for the compressor and other motors to start and run when necessary. However, that also means it always has some residual electrical power that you must discharge before touching it. 

Discharging a capacitor is a delicate and complex process, so only a trained person should do it. Sometimes, you can visually determine whether or not the capacitor is faulty or dead. A bulging or corroded capacitor must be replaced. The same applies to a capacitor leaking fluid or looking rusted.

7. Insufficient Refrigerant

The refrigerant flows through the air conditioning system and absorbs the heat from the air. That way, the air conditioner can produce cold air for the house. The gas flows through a closed loop, meaning that it never depletes, and you do not have to recharge the system. 

However, the air conditioner can lose refrigerant if the system becomes compromised. The refrigerant lines may have holes through which the gas leaks. Refrigerant leaks are not common, but they happen, so turn off the air conditioner if you suspect such a leak. 

Call for professional assistance, and do not turn on the unit until a technician seals the leaks.

8. Malfunctioning Compressor

Check the compressor if nothing else seems to be the problem. It may malfunction and stop compressing the refrigerant for the air conditioner. Without enough refrigerant, the air conditioner cannot produce cold air, which causes other parts to work harder and overheat the system. 

The extra work and extended run time affect the breaker and fuses over time. However, compressors rarely fail, so you must check other parts before testing this part of your air conditioner.

Bryant Air Conditioner Outdoor Compressor Unit Blowing Fuses – What to Do

Different air conditioner parts can cause the outdoor condenser unit or the compressor to malfunction and blow fuses. You can check the condenser coil, air filter, fan motor, and wiring in the outdoor unit, especially the connection to the thermostat. 

There is also a possibility that the breaker is faulty or the compressor has a malfunction affecting the fuses. This article on a Bryant air conditioner outdoor unit blowing circuit breaker contains resources for troubleshooting and fixing the faulty parts.
