Reset Button on AC Unit Outside and its Components: Causes and Solutions


In this article, we will learn about Reset Button on AC Unit Outside and its components along with causes and solutions. Cooling occurs via coils as hot, high pressure refrigerant passes through the outdoor air conditioning unit. It is possible for the system to overheat if there are any stumbling blocks in the process. You are in the right place if you need to reset your AC unit to prevent this problem. 

Reset Button on AC Unit Outside Basics & AC Components

A central air conditioner circulates cold air throughout your house, removing heat and humidity. Compressors, condenser coils, and evaporator coils make up refrigerant-powered air conditioners and cooling systems.

During the refrigerant changeover, these parts work together to quickly change from gas to liquid. As a result of the compressor, pressure and temperature increase. Before returning to the residence, the refrigerant passes through the evaporator coil.

Components of outside air conditioner unit

Condenser fan & coils

Condenser coils are where refrigerant flows after leaving the compressor. The coils are cooled off and heat is released into the atmosphere as a fan blows air over them.

Compressor

The compressor in your air conditioner applies pressure to the refrigerant arriving from within your home in order to make it more temperature adjustable so that it can transfer heat more efficiently.

AC Lines

In order to continue cooling your home, ac lines connect your indoor and outdoor units.

Reset Button on AC Unit Outside & Why Resetting

A tripped breaker is the main cause, but there are others. A central air conditioner has its own circuit breaker, as do most electrical appliances. In one case, there is an outside operation & while in the other, there is an internal operation. Circuit breakers save you from fires and explosions by shutting down your unit immediately when overloads are detected.

Upon returning power to your unit after an outage, your circuit could be overloaded due to the sudden change in electrical voltage. Normally, a circuit breaker will trip at this point. Your AC unit may stop working properly after a breaker is tripped. Sometimes a quick reset is all you need if the thermostat is set to a cool setting but you feel warm air.

Outside Air Conditioner Unit Workflow

Condenser units are the parts of your air conditioner that are located outside. Air conditioners absorb heat from your home’s air inside, and release it outside through the outside unit. Your air conditioner would not be able to remove the heat from your home without its outside unit.

You can better take care of your air conditioner if you know how it works. While homeowners are aware that the indoor portion of their air conditioner produces cool air, they are less aware of the outdoor component. 

Outside Air Conditioner Unit Resetting

Switch off Outside Unit of air conditioner

By using your thermostat, turn your air conditioning off. After you have reset it, it won’t call for cooling until you have completed the reset. You can find this button on your unit by looking for the red button or the switch. Unless your unit has a switch button, you may not be able to find one. Your only option is to reset manually or you can consult the owner’s manual for more information.

Switch off Circuit Breaker

If your heating and air conditioning system is connected or running, turn off the circuit breaker. You can find the breaker box by either looking for a metal panel or a metal box flush against a wall. There are times when it’s painted to blend in with your home, but it is usually a plain metallic color. In addition to garages, basements, closets, laundry rooms, crawl spaces, and the exterior of your home, it can also be found in these areas.

Hold the Breaker

Once the AC resets itself after a minute, it will operate normally again. You can turn on the thermostat after 30 minutes by gently turning it on. If it is working properly, you can set the thermostat to your desired temperature and wait for it to cool.

The thermostat should be turned back on to cool after 30 minutes. The thermostat should be set at least five degrees below the temperature of the room when checking if everything is working properly.

It is even easier if your AC unit has a reset button that will carry out this entire process automatically. You can find this button on your outdoor unit if your system has it. Red buttons are usually the most common for any kind of ac unit. A professional might be able to check your unit for you if you cannot find it or reach it. 

Basic Problem of Air Condenser

Refrigerant Leak

Small holes, cracks, or tears in the coil can cause your refrigerator to leak. Your HVAC system will have to work harder if there is a leak, so it won’t be able to cool appropriately. Moreover, your AC’s joints and connections can weaken over time. A professional HVAC technician can fix refrigerant leaks.

Electric Failure Issue

You may experience this problem if you frequently turn on and off your air conditioner. There is then a possibility that the fan controls will wear out. In order to start the unit, the compressor, condenser motor, fan motor, and blower motor are electrically connected.

When wires and terminals are corroded or disrupted, the compressor or motor cannot turn on due to corrosion and disruption. It may be necessary to seek the assistance of a professional if you are unable to resolve the issue on your own.

Clogging Drain Pipe

Drainage system failures are often caused by this problem. In an air conditioner, condensed water surrounds the evaporator coils when air passes over them. There is a flow of condensation down the drain pipe. The evaporator coil does not only contain water. The drain pan is also clogged with dirt and other particles, including dust.

Condenser Clogging

It is possible that windblown seeds, dust, and grass clippings have stuffed the cooling coil of an AC unit, causing a dirty coil. It is imperative to unclog the condenser so the unit can release the correct amount of cooling.

Noise Problem

It depends on the problem whether an AC unit makes a different noise. Some parts are loosening up & the blower may be having problems if there is a rattling or banging sound. Refrigerant leaks can cause squeaking sounds from the compressor or fan motor as well as bubbling or hissing sounds.

It might be an AC fan or a capacitor issue while you hear a clicking sound. A buzzing sound, on the other hand, is caused by faulty electrical components. A professional is required to deal with these issues.

Sensor Issues

If you have a faulty sensor, you will notice certain signs. Having a malfunctioning air conditioner would make the environment uncomfortable, as the temperature would not be maintained at your desired level. Without touching the part, you can check the sensor near the evaporator coil. You can contact an HVAC professional if you’re concerned about sensor problems.

How can you look after outside air conditioner unit?

As the condenser unit of your air conditioner is located outside, it needs to be well taken care of and protected from dirt and debris. A technician can perform annual maintenance on your outside air conditioning unit to keep it running efficiently.

Your condenser unit will be inspected for any problems and cleaned of any dirt accumulated over the year during annual maintenance. Keeping the area around your condenser unit clear is another great way to protect it. It is important to remove any plants or grass that has grown around the outside unit and other obstructions to allow proper airflow into your system.

Why you call professional for air conditioner unit?

Do not try to reset your AC unit back to back if it still is not working or if your circuit breaker keeps tripping. Among the other possible causes are a dirty air filter, faulty wiring, a malfunctioning fan motor, and a broken compressor.
