Even though the A/C unit is outside, the breaker for it will be in the entrance panel box inside your home. It should be clearly marked.
The purpose of an outside AC breaker is to protect the air conditioning unit from electrical overloads. It functions by interrupting the flow of electricity to the AC unit when there is a surge in current, preventing damage to the unit and reducing the risk of electrical fires in the residential electrical system.
If your AC won't turn on after flipping the breaker, it could be due to a faulty thermostat, a blown fuse, a tripped circuit breaker, or a malfunctioning AC unit. It is recommended to check these components and consult a professional if needed.
The inside fan blows air through the ac coils to cool the air. It should be on a separate breaker or fuse circuit from the outside unit. See if there is a fuse box on the side of the inside unit and check the breakers in the house main breaker box. Also stand quietly beside the inside unit and listen for the fan motor running. If the motor is heard running then either the fan drive belt has broken, or the ac coils are clogged preventing air from flowing.
Read the literature for the ac condensing unit, or the tag on the outside of the unit. Minimum circuit ampacity= minimum breaker, wire and fuse size. Maximum circuit ampacity= the maximum size. Your circuit breaker, wire size and disconnect fuses should all be at or between those 2 numbers.
No
Your portable AC may be tripping the breaker due to an overload of electrical current. This can happen if the AC unit is drawing too much power or if there is a fault in the electrical system. It is important to check the power requirements of the AC unit and ensure it is plugged into a dedicated circuit to prevent tripping the breaker. If the issue persists, it may be necessary to have a professional inspect the unit for any potential problems.
A breaker for an AC unit is a safety device that protects the unit from electrical overload. It automatically shuts off the power supply to the AC unit if there is a surge in electricity, preventing damage to the unit and reducing the risk of fire.
Yes
The filter on your outside AC unit is typically located near the air intake grille or on the side of the unit. It is important to regularly check and replace the filter to ensure proper airflow and efficiency of your AC system.
If the breaker only trips once a week you may have a bad breaker or the breaker may not be large enough for your A/C unit. You should also have an electrician look for any loose connections from the unit to the breaker panel. (It is not uncommon to have a bad breaker)
the compressor is not running. Check your breakers.
The recommended AC breaker size for a 240V air conditioning unit is typically 20 amps.
