How to Reset Your Air Conditioner When It Is Not Working?

Are you experiencing issues with your air conditioner? Is it not cooling your home properly or making strange noises? One of the first troubleshooting steps you can take is resetting your air conditioner. This comprehensive guide will walk you through the steps of resetting your air conditioner and offer helpful tips to ensure it’s done safely and effectively.

Why Do You Need to Reset Your AC?

Despite being a reliable cooling solution, air conditioners occasionally encounter hiccups that can be easily rectified by resetting the system. Here are some common issues that can make resetting your air conditioner necessary:

Frozen Coils

If your unit’s evaporator coils are frozen, resetting the air conditioner can help it restore normal function. Frozen coils commonly occur due to blocked air filters or low refrigerant levels. You can allow the coils to thaw by switching off the system for a few hours. Once the ice has melted, switch it back on and observe if it operates correctly.

Tripped Circuit Breaker

Another common issue that can necessitate resetting an air conditioner is a tripped circuit breaker. When too much power is drawn, the circuit breaker will cut off the power supply to prevent overloading. If your air conditioner unit is not blowing cold air, but the fan is still operational, check the circuit breaker and reset if it’s tripped.

Malfunctioning Thermostat

A malfunctioning thermostat can cause your air conditioner to run continuously or fail to switch on. If you suspect that your thermostat isn’t working, try resetting it by turning it off for a few moments before switching it back on. If the issue persists, there might be a more complex issue, like a wiring problem or a faulty thermostat. In that case, seek the help of a qualified technician.

How to Reset Different Types of Air Conditioners

Resetting your air conditioner can fix a range of issues that may occur from time to time. However, it’s important to know how to properly reset your air conditioner to avoid causing further damage or voiding your warranty. Each type of air conditioning unit comes with a unique reset process. Here, we’re sharing some easy steps for any homeowner to follow:

Central Air Conditioner

Resetting a central air conditioner may require a professional technician. However, there are a few steps you can take before scheduling a service appointment:

1. Check the thermostat batteries to make sure they are charged.
2. Inspect the circuit breaker to make sure it hasn’t tripped.
3. Replace the air filters, as dirty filters can cause issues with the unit.
4. Turn off the air conditioner at the thermostat.
5. Wait 30 seconds and turn the air conditioner back on.

If the unit still isn’t working properly, contact a technician.

Window Unit Air Conditioner

Resetting a window unit air conditioner is a bit simpler:

1. Unplug the unit and wait for 30 seconds.
2. Plug the unit back in and wait for it to restart.

If the unit still isn’t working properly, try cleaning the air filter. If that doesn’t work, contact a technician.

Mini Split Air Conditioning System

Resetting a mini-split system air conditioner can be more complicated:

1. Turn off the power to the unit.
2. Wait for 30 seconds, then turn the power back on.
3. Press the reset button on the outdoor unit if it’s available.
4. Wait for the unit to start up again.

If the unit still isn’t working properly, contact a technician.

Portable Air Conditioner

Resetting a portable air conditioner is similar to resetting a window unit:

1. Unplug the unit and wait for 30 seconds.
2. Plug the unit back in and wait for it to restart.

If the unit still isn’t working properly, try cleaning the air filter. If that doesn’t work, contact a technician.

Safety Precautions When Resetting an Air Conditioner

Resetting an air conditioner can be a simple task, but it’s important to take the necessary safety precautions to avoid potential hazards. Here are some tips and guidelines to ensure safety when resetting an air conditioner:

1. Proper Grounding

Before attempting to reset your air conditioner, make sure you are properly grounded by standing on a dry surface and wearing rubber-soled shoes. This will help prevent electrocution.

2. Avoid Electrocution

Be sure to turn off the power supply to your air conditioner before attempting to reset it. This can be done by switching off the circuit breaker box or unplugging the unit from the power source. It’s also important to avoid touching any electrical components or wires with bare hands.

3. Safely Accessing and Handling Circuit Breaker Box and Thermostat

When accessing the circuit breaker box and thermostat, be sure to use a sturdy ladder and avoid overreaching or leaning too far. Always handle the circuit breaker box and thermostat with care and avoid any sharp edges or hot surfaces, as they can cause injury.

By taking these precautions, you can safely reset your air conditioner and avoid potential hazards.

Tips for Maintaining and Troubleshooting Air Conditioners

While resetting your air conditioner can fix some issues, it’s important to maintain and troubleshoot your unit regularly to prevent future problems. Here are some tips:

• Regularly change the filters: Dirty filters can restrict airflow and cause freezing.
• Clean the condenser coil and evaporator coil: Dirty coils can reduce efficiency and cause overheating.
• Check for AC Refrigerant leaks: Low refrigerant levels can cause the air conditioning to fail.
• Make sure the thermostat is working correctly: Malfunctioning thermostats can cause the system to run excessively or not at all.
• Ensure that the outside unit is clear of debris: Clear away any leaves, grass, or other debris that may have accumulated around the unit.

By following these guidelines, you can keep your air conditioner working efficiently and prevent issues that may require a reset. Regular maintenance can go a long way in preventing common air conditioner problems. Always remember to switch off your air conditioner before carrying out any maintenance procedure.
