The heatwave and summer heat calls for the need for an air conditioner. But AC problems can make it challenging to have a cool summer. For instance, if your outside AC unit is not turning on, you might be deprived of cool air. To eliminate this problem soon, you need to know the cause. Carry on reading this blog to know what is causing your AC to malfunction.

Why is My Outside AC Unit Not Turning On?

Calling an AC repair service might help you identify and fix the problem effectively. But before calling in a professional, you can try these:

1. Take a Look at the Shut-Off Switch

Usually, AC units have a shut-off switch close to the outdoor system, in a metal box that might be attached to your house. Check if the switch is in an off position, as it can be why your outside AC unit isn’t working.

2. Verify if the Thermostat is Set to COOL

It might sound obvious to set the thermostat to cool. Still, many people might mistakenly leave it at a raised temperature or turn it off entirely. This typically happens when you adjust your thermostat constantly. Therefore, make sure the thermostat is set to the COOL position. Then, turn the temperature down to five degrees below the room’s current temperature. You’re good to go if the AC powers on and the room starts cooling. Otherwise, there might be another issue.

3. Check the Power Switch on Your AC Inside Unit

If your outside AC is still not turning on, take a look at your indoor system. Locate the power switch near the HVAC system, and turn the unit off. You or someone else might have accidentally flipped the switch off. Consequently, the entire unit might power down.

4. Look for a Tripped Blown Fuse or Circuit Breaker

The outside AC unit might stop working if there’s a blown fuse to the circuit breaker. Loose wires, overworked AC units, loose wires, and aging can overload the circuit breaker, leading to a blown fuse. To verify that you’re having this issue, you’ll need to check two locations: Main electric panel & shut-off box.

The circuit panel was a ‘fuse box’ in older homes. Take a look at the fuse box or circuit panel to see if you’ve blown a fuse. If so, then you’ll need to replace the broken fuse. Your home might have a circuit breaker. In that case, look for tripped circuits. If you spot any tripped circuits, flip the switch to ‘off’, then to the ‘on’ position. If the breaker immediately trips after you turn it back on, call in a professional and avoid turning it back on again; it could damage the household appliances.

A blown fuse at the safety shut-off box can also be the culprit behind your outside AC unit not turning on. You’ll find the shit-off box near your AC unit. Check if you have a blown fuse that needs to be replaced. Replace the fuse even if it doesn’t appear damaged. If the problem returns after this, call in an expert.

5. Reset the System

A simple system reset might fix the problem. Look for a reset switch by your cooling system. If you see the switch, push it to check if anything happens. In case you don’t have the switch, try a manual restart instead. To do so, power off the AC at the thermostat and wait five minutes before turning it back on. Believe it or not, restarting your AC might actually work.
