Dealing with a broken AC<\/a> in the summer heat is zero fun, especially when it keeps tripping the breaker. But what causes an AC circuit breaker to trip?<\/span>\u00a0<\/span><\/p>\n

At RB Heating ClimateCare, we service home and business owners across Kemptville and the surrounding areas, specializing in heating<\/a>, cooling<\/a>, and air quality<\/a>. We know air conditioners better than most. When the circuit breaker trips due to the AC, there could be many reasons why.<\/span>\u00a0<\/span><\/p>\n

What Causes an AC Circuit Breaker to Trip?<\/b><\/h2>\n

To keep our customers informed, we\u2019ve created a list of what causes an AC circuit breaker to trip and how to reset the AC circuit breaker.<\/span>\u00a0<\/span><\/p>\n

1. Condenser Coil Needs a Cleaning<\/span><\/b>\u00a0<\/span><\/h3>\n

If you\u2019re wondering, \u201cWhy does my AC keep short-circuiting?\u201d the culprit could be the condenser coil. A dirty coil might cause an AC to short circuit because the dirt on the coil blocks the exterior portion of your AC unit to release heat. Over time, the unit begins to overheat. As a result, the AC trips the breaker immediately to avoid a fire.<\/span>\u00a0<\/span><\/p>\n

Cleaning the AC condenser coil isn\u2019t difficult. If you\u2019re concerned about doing it on your own, call an expert. RB Heating ClimateCare offers many AC services, including cleaning and maintenance<\/a>.<\/span>\u00a0<\/span><\/p>\n

2. Outdated AC<\/span><\/b>\u00a0<\/span><\/h3>\n

Can an AC cause a short circuit if it\u2019s too old? Absolutely. Your AC unit can last you from 12-17 years if properly maintained. Eventually, though, all air conditioners need to be replaced. If your unit is aging, it could short-circuit and cause the breaker to trip.<\/span>\u00a0<\/span><\/p>\n

If an outdated AC is an issue, replacing the unit is the best plan of action. Alternatively, some parts may be replaceable to update the unit.<\/span>\u00a0<\/span><\/p>\n

3. Dirty Air Filter Shorting the Power<\/span><\/b>\u00a0<\/span><\/h3>\n

Like the condenser coil, a dirty filter<\/a> can impede electricity to your AC. Before air flows into your home, it flows through the AC filter. As the filter collects dust and debris, it begins to block up. When it gets too blocked, airflow slows or halts. This makes your AC work harder trying to push cold air into your home, tripping the breaker.<\/span>\u00a0<\/span><\/p>\n

Replacing your AC filter isn\u2019t difficult. You should replace the filter once every 90-days.<\/span>\u00a0<\/span><\/p>\n

4. Refrigerant Levels Are Low<\/span><\/b>\u00a0<\/span><\/h3>\n

Refrigerant is a liquid used to operate cooling appliances like your fridge and AC unit. The liquid transforms to gas and back again, drawing heat out of your home (in the case of an AC). As refrigerant levels dwindle, the compressor is left without sufficient lubricant to function. This could cause it to stall, tripping your breaker.<\/span>\u00a0<\/span><\/p>\n

Sadly, low refrigerant usually means a leak in your system. If you\u2019re concerned refrigerant is the issue, contact your AC repair<\/a> service as soon as possible.<\/span>\u00a0<\/span><\/p>\n

How to Fix It: Reset the Breaker<\/span><\/b>\u00a0<\/span><\/h2>\n

Now that you know what causes an AC circuit breaker to trip, you should know how to reset the breaker. Follow these steps to get your AC back in business:<\/span>\u00a0<\/span><\/p>\n

    \n
  1. Turn your AC unit off and flip the breaker powering it.<\/span><\/li>\n
  2. Locate the reset button on your unit.<\/span><\/li>\n
  3. Press and hold the button for 5-seconds.<\/span><\/li>\n
  4. Switch on the breaker and turn on your AC unit.<\/span>\u00a0\u00a0<\/span><\/li>\n<\/ol>\n
