Does your AC unit constantly trip your home’s circuit breaker when it’s running?
The circuit breaker, of course, is an important safety mechanism in modern homes and businesses. It’s designed to interrupt the flow of electricity when there’s too much current present.
If the amount of current running through the circuit breaker exceeds the limit for which it’s rated, it will “trip.”
So, why is your AC unit tripping the circuit breaker exactly?
Don’t Just Reset the Circuit Breaker
Before we reveal why AC units trip circuit breakers, it’s important to note that you shouldn’t just reset the circuit breaker.
Although it sounds like an easy and effective solution, it increases the risk of a house fire. After all, the primary purpose of a circuit breaker is to stop excessive amounts of electricity from flowing into your home.
If the circuit breaker trips and you simply reset it, the underlying problem that initially caused the excess current will remain.
Therefore, you must determine why your AC unit is drawing excess current so that you can prevent it from constantly tripping the circuit breaker.
Dirty Air Filter
You might be surprised to learn that a dirty air filter can cause an AC unit to trip the circuit breaker.
As dirt accumulates on the inside of the air filter, it restricts the flow of air. As a result, the AC unit must run for a longer period to achieve the desired temperature to which the thermostat is set.
Combined with the excess load placed on the blower, this causes the AC unit to draw more electricity, thus increasing the risk of a tripped circuit breaker.
Low Refrigerant
In addition to a dirty air filter, low refrigerant can cause your AC unit to trip the circuit breaker.
All AC units have refrigerant. It’s the substance that’s responsible for absorbing heat inside your home so that it can be transferred to outside your home.
When refrigerant leaks or otherwise escapes the system, the AC will draw more electricity in an effort to cool your home’s interior.
Wiring Problems
Problems with your AC unit’s electrical wiring may also cause it to trip the circuit breaker. Wires don’t last forever.
After being exposed to temperature and humidity fluctuations, they will degrade. Some wires may loosen, whereas others may shed their exterior coating.
When this occurs, it may cause your AC unit to draw too much electricity, thereby tripping the circuit breaker.
