The Problem with Evaporator Coils
The evaporator coil is a crucial component of your air conditioning unit. Located in the indoor air handler, its primary function is to cool the heated air pulled from inside your house. However, if there is a blocked air filter or any other airflow problem, ice can accumulate on the evaporator coils, causing your machine to shut down on a regular basis.
The Culprit: Frozen Coils
When your air conditioner coils become frozen over, it becomes necessary to turn off the unit. The evaporator coils, situated inside the air handler, can accumulate ice over time due to clogged air filters and other airflow concerns. This causes the engine to cycle for too long, leading to frequent shutdowns.
Short-Cycling and Overheating
If your air conditioner shuts down after only 15 minutes of operation, there may be an underlying issue to blame. Overheating is a common cause, often due to a buildup of dirt within the compressor unit. However, it could also be caused by a refrigerant leak or other factors. Another possibility is a malfunctioning thermostat.
Common Reasons for Compressor Shutdown
Compressors can shut down unexpectedly and frequently for various reasons. Excessive or insufficient refrigerant charge can be one culprit. Additionally, dirty condenser coils can cause rapid cycling when they become blocked with dirt and debris from the air.
Portable Air Conditioner Troubles
If your portable air conditioner keeps shutting down, clogged air filters and coils could be to blame. When these components become blocked with dirt, airflow is impeded, resulting in decreased cooling effectiveness. In extreme cases, limited airflow can cause the device to overheat and automatically shut down.
To prevent your air conditioner from turning on and off too quickly, there are a few steps you can take. First, check and clean your air filter regularly as a blocked filter can cause a range of problems. Ensure your thermostat is working correctly and monitor the refrigerant levels in your system. It may also be wise to consider replacing the low-pressure control switch and ensuring that the compressor is in proper working order.
Troubleshooting Window Air Conditioners
If your window air conditioner shuts off on its own, several factors could be at play. Overheating of the compressor or a clogged filter can be causes for shutdowns. Additionally, refrigerant leakage can occur over time, depending on the age of your air conditioner. It’s also possible that the room has reached the desired temperature, prompting the thermostat to switch off the cooling mode.
Understanding Short Cycling
Short cycling refers to the phenomenon where your air conditioner switches on and off in quick bursts, failing to adequately cool your home. While the typical air conditioning cycle lasts around 20 minutes, short cycling can occur due to various reasons, such as an improperly fitted or blocked thermostat, refrigerant leaks, iced coils, or an oversized HVAC system.
Dealing with Tripped Breakers
Tripping the circuit breaker is a common occurrence when it comes to air conditioners. A malfunctioning air conditioner can overheat, causing it to pull more electrical current than the circuit can handle, resulting in a tripped breaker. However, external electrical faults, such as voltage issues or power spikes, can also cause compressor overheating.
Resetting Your Air Conditioner
If you need to reset your air conditioning unit, follow these steps. Start by turning off the air conditioning system at the thermostat. Then, switch off the air conditioning machine itself before locating and resetting the circuit breaker for your central air conditioning unit. Wait for 30 seconds before resetting the thermostat.
Optimum Performance and Maintenance
Properly sized and operating air conditioners typically operate in cycles of around 15 to 20 minutes each. If your unit only runs for a few minutes at a time, it may be oversized for your house. Remember, regular maintenance is key to preventing common issues with air conditioners.
Now that you have a better understanding of why your Arctic Air keeps turning off, you can take the necessary steps to address the problem. Keep your unit well-maintained, and if issues persist, consult a professional. Stay cool and comfortable all summer long!
