What if your air conditioner won’t switch on? Although air conditioners might function flawlessly for years, faults can arise at any time. Fortunately, there are several diagnostic suggestions that might assist. We’ll go over a few reasons why your exterior air conditioner won’t switch on, as well as some easy troubleshooting steps that may help you address the problem.
Whether you have a split-system conditioning unit at house or business, it won’t chill the room adequately until both inner and external condenser components are working. Most individuals, businesses, and management companies have encountered a scenario in which the exterior air conditioning unit is not functioning while the interior air conditioning unit is.
You may do several things before hiring an HVAC specialist if your exterior air conditioner isn’t operating correctly. And here is what we suggest:
1. Check the Switch:
Many air conditioning units include a shut-off control near the exterior unit. It is usually kept in a metal container linked to your house. The sealed button on an ac unit may be at its „off“ setting if it won’t be turning on. If the air conditioner was recently fixed, it’s possible that this control was forgotten. Ensure that switch is now in the appropriate position by inspecting this region.
2. Thermostat Setting:
Although this may appear to be common sense, it’s astonishing how many individuals make this fundamental error. This issue is especially common in houses where the temperature is altered regularly. Ensure your AC unit is tuned to „cooling“ if you would like conditioned air to flow out of it. Configure the equipment to COOL and then reduce the temperature by 5 degrees underneath the current temperature to ensure that it’s in functioning condition. The device is operational if you notice your ac unit turn on. Whenever you don’t, users can end up with a new problem.
3. Switch Inside Power ON:
Still having a problem with your air conditioner not kicking on? Double-check that your internal system is in working order if that’s the case. To begin, locate the power button near your Ac unit and flip it off. The said switch is usually located near your device in your loft, cupboard, or basement.
Even though this power supply resembles a switch, this is typical for householders to turn it off unintentionally. If you switch off this control, the electricity to your compressor is turned off, which might cause the inside system to freeze.
4. Circuit Breaker:
If you’ve had a power failure in your house, it can quickly flip a fuse box or blow a circuit breaker, turning off your air conditioning unit. Examine in the two following places to see whether you’re encountering this problem:
A. Main Panel:
In earlier homes, this was referred to as a junction box; it is referred to as a circuit board in contemporary homes. Check to see whether a fuse has burned. When you have, don’t worry—it’s simple to repair! Try replacing the blown fuse with a new one. Look for just about any zonked connections if your house has a fuse box. If you notice any, turn the toggle to „on“ and then again to „off.“
B. Fuse Box Near AC:
A broken circuit in a clamping box could be the cause of your air conditioner not switching on. This ought to be near to your air conditioner. Inspect to determine whether you got a damaged fuse, and why, replace it immediately. Even though the fuse appears to be in good condition, replace it nevertheless. If this resolves the situation, but it reappears, contact an ac service company. Rather than wasting time tinkering with your machine, these professionals can take care of the problem right away.
5. System Reset:
If the exterior AC unit is not operating but is operating inside, the problem can be resolved by rebooting a standard system. Go to your air conditioning system and seek out a reset button to attempt this procedure. Most air conditioning units do not even have them; some do. Consider giving it a nudge if you find it and see what happens. You’ll need to restart manually when you don’t have that switch. To begin, turn down your air conditioner at the controller, pause for 5 minutes, and then switch it back up. Because air conditioning units can turn off over a range of factors, performing a reset may be worthwhile.
6. Check the Water Line:
Condensation is produced whenever your air conditioner is performing effectively. This would be drained into a drain pipe. When it’s too moist outside, though, this drain pipe might clog. The protective relay may trigger when it occurs, causing the refrigeration system to cease down. Utilizing a parched suction to vacuum up the clog is one technique to address this.
7. Check the Motor:
If the air conditioner was producing strange noises when it stopped functioning completely, the problem might be a damaged motor. A capacitance test may be used to determine if the motor really has any life remaining in there.
If the problem is with your motor, obtain many estimates for how expensive it will be to repair it versus how expensive it will be to change the Air condition.
8. Faulty Power Line:
Often the problem isn’t so serious; it’s simply that you’re expecting the scariest. So, look at the essential items that are right next to you, such as the power cable.
If your item has been kept for a year, the power cable may break and wear out. Power failures might potentially cause the cable to be damaged.
Unplug the cable to conduct a thorough investigation. You’ll have to change it if it exhibits symptoms of wear.
The Bottom Line:
Kudos if you found out why your air conditioner wouldn’t come on and solved the problem! But so, we urge that you get an expert to do a thorough examination to prevent future difficulties.
You may minimize future HVAC failures by letting an Ac specialist conduct safety checks and remaining ahead of schedule.
FAQ – Outside AC Unit won’t Turn on
How do I know if my AC thermostat is bad??
It can be challenging to determine if your AC thermostat is bad without investigating further. However, there are subtle indications that your air conditioner’s outside unit or thermostat may not function correctly. For instance, the exterior ac unit might switch on for an excessively brief period before shutting off again. If you notice this behavior, there’s a chance the thermostat has failed and cannot send an appropriate signal to activate the system.
Another sign that may indicate your thermostat has failed is if it continues to crank up inside heat even when you’re using the AC unit outside. As mentioned above, the thermostat sends signals that set off either cooling or heating activities depending on what you’ve selected with the switch on your thermostat or remote. If your thermostat sends out a signal to activate the AC unit, but it never turns on, this may indicate a problem with the outside ac unit’s thermostat.
How do I know if my AC fuse is blown?
The exterior AC unit will not turn on if your AC fuse is blown. Fuses are essential for preventing an overload of electricity that can damage appliances or even start a fire. If you think your AC fuse may be blown, it’s best to consult with a professional to help identify the problem and fix it.
In some cases, you might be able to determine whether or not your fuse is blown by checking the fuse box. The fuse box is usually located in a closet or in the basement. Look for a red or black box with several switches inside. Each switch corresponds to one appliance in your home. If one of the switches is in the off position, the appliance is receiving any power. If you’re not sure which device operates on that switch, consult a professional or else risk damaging your appliances by switching the controls up and down. If you change them around, note which switches correspond to which appliances before turning anything back on.
Why do capacitors „go bad“?
A capacitor is a small electronic device that stores energy, which will then be released in an electric current. A capacitor behaves the same as a battery does. With capacitors, however, it can be charged or discharged rapidly. The life of a capacitor usually spans anywhere from 5-15 years, depending on the quality of the product itself. If you are experiencing problems with your exterior ac unit’s fan, there’s a chance that your moving parts need oiling or else your compressor needs to be replaced due to age.
Outside AC Unit Not Running But Inside Is: What’s Going On?
If your air conditioner isn’t running, but the inside is cool, there’s a good chance you have a dirty filter. Filters trap particles like dust and dirt, eventually clog up the system, and prevent it from working properly. If the filter is dirty, it will need to be replaced. You can usually find the filter behind the return-air grille.
If your air conditioner still isn’t running after replacing the filter, you might want to check the power supply. Ensure that both the switch on the thermostat and the breaker box are turned on. If they are turned on and your air conditioner still isn’t running, you may need to call a professional to investigate further.
