Circuit Breaker Tripping: Common Causes

To identify the reason why your circuit breaker trips frequently, you need to understand the common causes. In this section, we will discuss the possible causes in detail. We will start by explaining how a dirty air filter restricting airflow can cause your circuit breaker to trip.

Why Does My Furnace Keep Tripping The Breaker

Dirty Air Filter Restricting Airflow in HVAC System

Air filters are essential for fresh, breathable air in our homes. But when they get dirty, they can block airflow in our HVAC systems – causing the circuit breakers to trip! The restricted airflow makes the equipment overheat, triggering the breaker.

Dirt and dust particles will build up on the filter over time. This reduces airflow and puts extra strain on the electrical system, forcing the breaker to switch off before a fire hazard occurs.

It’s advised to change air filters every 3 months, or monthly if you have pets or allergies. Doing this keeps the air flowing freely, preventing blockages and keeping your home safe.

Don’t ignore a clogged filter – it could lead to expensive repairs or replacement of your HVAC system. Keep your family safe and your system running smoothly by changing air filters regularly!

Ground Faults and Wiring Issues in HVAC System

Ground faults and wiring issues can cause circuit breakers to trip. These may be due to aged or damaged wire insulation, incorrect installation, or improper grounding. 

Ground faults occur when electric current travels through an unintended path, like a body. Wiring problems can lead to overheating or damage to appliances. Poorly installed circuits, loose connections, and worn-out components can also cause circuit breaker tripping.

It’s important to have qualified electricians inspect and maintain electrical systems regularly. In 1992, a boat exploded due to an electrical fire caused by a ground fault. This shows how important it is to properly ground and regularly inspect electrical systems. 

Proper knowledge of these matters can save lives!

Capacitor or Blower Motor Failure in HVAC System

When it comes to circuit breaker tripping, it could be a capacitor or blower motor failure. Motors and capacitors that are worn out or inefficient can cause the motor to work harder. This generates more heat and eventually trips the breaker.

To get a better understanding of these failures, here’s a table:

Common CausesSymptoms
Worn-out CapacitorMotor humming but not startingWeak airflowDifficulty in starting the motor
Inefficient MotorMotor running too hotBurning odor from the motor
Electrical IssuesTripped Circuit BreakerFailing Motor

Don’t forget, improperly-sized capacitors can also cause blower motors to fail prematurely. Always use the correct size for your system.

If you’re having any of these issues, call a professional HVAC technician right away. They’ll diagnose the problem and suggest repairs or replacements. 

To prevent future capacitor or blower motor failure, schedule regular maintenance including cleaning and replacing air filters once a month, as well as making sure all parts are lubricated and working properly. Doing this can help avoid breakdowns and extend the system’s lifespan.

Electrical power surges are like the Kardashians – they cause a lot of drama but nobody really knows how they got there.

Short Circuits and Electrical Power Surges in HVAC System

Short circuits and power surges are two of the most common reasons why circuit breakers trip.

  • A short circuit is when an unintended connection is made between two points in a circuit. It causes a sudden surge of electricity. 
  • Power surges occur when there is a sudden increase in voltage.
  • Short circuits can be caused by a range of factors. Damaged insulation on wires, faulty switches/appliances, and overloaded circuits are all danger signs. 
  • To prevent them, regularly inspect electrical components and equipment that are often used.
  • Power surges can come from lightning strikes, fluctuations in the grid’s power, or starting large motors/equipment at home. 
  • To protect against these, install surge protectors on electrical equipment.

Occasional tripping is normal for some circuits with safety features. But if it trips too often, contact an electrician to avoid fire hazards. Ready to get sleuthing? These troubleshooting solutions will have you feeling like Sherlock in no time.

  • Strip insulation: If faults can’t be seen or found by a multimeter, remove the insulation to check the wires closely.
  • Replace faulty components: Replace faulty wires or components ASAP to avoid danger.

Also, make sure enough space is around electrical components, otherwise, they may overheat and start a fire. Have a qualified electrician do the electrical inspection for the best results. Before removing wires, label each wire with its proper function. 

That way, attaching them back becomes easier later, and there’s no confusion!

Test Capacitor and Blower Motor of the Furnace Unit

It can be annoying when your air conditioner’s blower motor and capacitor aren’t working right. To find the cause, you’ll need to do tests on both components. Here’s a guide to help you:

  • Turn off the power: Make sure to turn off the AC power at the circuit breaker before starting repairs.
  • Test the Blower Motor: Use a multimeter to check the voltage. If it is getting voltage but not spinning, that means your motor has failed and needs to be replaced.
  • Test the Capacitor: Check if there’s continuity between the terminals with your multimeter. If yes, it passed. If not, it needs to be replaced.

Remember, capacitors come in all shapes and sizes for various motors. So be careful to choose one with the correct specifications for your blower model. Also, according to HVAC Brain, HVAC systems can filter out allergens like mold spores, bacteria, dust mites, and pollen.
