Is there a breaker on my AC unit?
Your air conditioning unit has two breakers; one operates the outside unit while the other operates the inside. If the breakers appear tripped, turn the breakers off and then back on to reset them.
How do I know if my AC breaker is tripped?
How do you turn on the AC breaker?
Carefully open the panel and find the breaker switch labeled outdoor AC. Flip the breaker switch to the on position. Don’t use any tools, and never stand in water when turning breakers on and off. Many outdoor units also have a second electrical disconnect mounted outside in a rainproof box near the unit.
Where is the reset button on outside AC unit?
Look for it first around on the exterior of your machine, especially along the bottom edge near the ground. An AC’s reset button is typically red and visible, so it should be easy to spot. If you don’t see a reset button on the outside, it could be located inside the unit behind the service panel.
Why is my AC inside unit not turning on?
First make sure there is power to the indoor unit and that a switch or breaker isn’t off. Try setting the thermostat fan switch to the “on” position. Feel for air coming out of the vents. If it is in the air conditioning mode, check for ice around the evaporator coil and on the refrigerant lines at the indoor unit.
Where is the AC fuse?
What is an AC fuse? The fuse is a wire inside a glass casing, found in the disconnection box connected to your AC. The fuse is a protective measure meant to protect your air conditioner from electrical damage.
Why would my AC breaker trip?
Typically, your AC breaker trips when there’s a short circuit, the AC is overworking or a part is bad or malfunctioning. If you continue to run your AC, you could permanently damage the air conditioner. Get a professional AC repair tech out as soon as you can.
What do I do if my breaker won’t reset?
If the circuit breaker won’t reset and trips immediately, the problem might be a short circuit. A short circuit can cause broken appliances, overheating, or even be a fire hazard. If you suspect a short circuit is the reason your circuit breaker keeps tripping, leave the breaker off and call a licensed electrician.
How long does it take for an AC unit to reset?
After you’ve turned the system back on, it will take a bit of time for the air conditioner’s internal circuitry to reset. It usually takes about 30 minutes, so sit tight until then. 5. Switch on the AC system at the thermostat.
What do you do when your outside AC unit stops working?
Outside AC Unit Won’t Turn On? What to Do Before Calling for Repairs Make sure the thermostat is set to COOL. Check the emergency or shut-off switch. Check the inside unit’s power switch. Look for a blown fuse or tripped circuit breaker. Look for problems with your condensate drain line. Try resetting the air conditioner.
Why is my air conditioner on but not blowing air?
If the AC unit is running, but there is no air through the vents, you are likely dealing with a fan capacitor that has reached the end of its life. Fan capacitors help get your HVAC system’s outdoor and indoor fan motors blowing and your compressor running.
Can a blown fuse cause AC not to work?
First of all, your electrical system might be having problems. While this prevents serious trouble such as electrical fires, it also means that a single blown fuse can cause the entire air conditioner to stop working.
How do I check my home AC fuse?
The best way to test for a blown fuse is by using a voltmeter. To verify that you have a blown fuse on hand, the first step is to locate the disconnect box. Lift or swing open the outer and inner cover of the disconnect box to expose the cables. Check the voltmeter to make sure that it is functioning properly.
Can a circuit breaker reset itself?
Type 1 are auto resettable, and once tripped, will attempt to reset the circuit, or ‘cycle’, as the internal elements of the breaker cool down. Type 3 circuit breakers are manual resettable, and require that a button or lever be pushed in order to reset the breaker.
Why is my AC not working after power outage?
Find the breaker box in your home and flip the breaker for the AC to the “off” position. Flip the breaker for the AC back on.

What is it when the outside AC unit is running but the inside is not?
A jammed or clogged condenser coil could be the cause of your air conditioner running but not dropping temperatures inside. The condenser fan pulls air into the outside device through the condenser coil to extract heat energy from your home while it’s working properly.
Where is the fuse on a window AC?
The fuse, particularly common in newer models, helps protect the electronic control. Check to ensure that the power supply to your unit is good, then unplug the air conditioner and remove the cabinet cover. The fuse will be located near the circuit board; check to see if it has blown, using a multi-meter if necessary.
How long does an AC fuse last?
The lifespan of a fuse can be up to 20 years. AC fuses are usually what is known as ‘slo-blow’ or ‘time delay’ fuses. This means that they are at work every time you turn the machine on and off and eventually, will simply wear out due to the strain of the operation.
Can a dirty air filter cause AC not to cool?
A dirty air filter restricts the flow of cold air, causing it to build up inside the air conditioner and lower the internal temperature. Uneven Cooling: Even if it’s not enough to cause freezing, that restricted airflow isn’t good for your air conditioner’s cooling power.
Where is AC circuit breaker?
The circuit breaker box (a grey metallic box) is usually located in these areas: garage, basement, closets, laundry room or an exterior part of your home. Just look for a switch that is “tripped,” meaning that’s it’s moved to the neutral position.
