Air conditioners have become indispensable in keeping your temperament and indoor space cool. Rising tempers, mood swings, unnecessary frustration can all be attributed to problems created by high heat. Suffice to say, ACs are no longer a luxury item. Instead, they are a necessity of life, especially in Florida, where the summers can be brutal with high temperatures and high humidity.
So, when the AC does not turn on, one is bound to panic and start thinking the worst. Putting rest to your fears, we want to discuss the common reasons for them. This knowledge will help you understand that there could be simple solutions. Therefore, you shouldn’t jump to the conclusion your cooling system has gone dead on you.
8 Reasons Behind AC Not Turning On And Their Solution
1. Thermostat Batteries Are Drained – The thermostat communicates your temperature needs to the cooling system. If the thermostat batteries have no juice, its display will not power on, and there is no way it will be able to communicate with the AC. As a result, the AC does not switch on. Usually, the thermostat has a battery level indicator to help you keep track of the power remaining in the batteries. Yet, most of us miss this little detail because we don’t continuously check the thermostat.
The Solution – Replace the old batteries of the thermostat with fresh ones. This will bring up the display screen once more and help communicate your requirements to the HVAC system. Your AC should now work fine.
2. The Circuit Breaker Is Tripped – As a part of the safety system, the circuit breaker trips whenever there is a power surge or a short circuit. This essential safeguard ensures your AC does not fry or an electrical fire does not break out.
The Solution – If the circuit breaker tripped due to a power surge, all you have to do is push it back to the “On” position, and your AC will resume its functions. On the other hand, if the breaker tripped due to a short circuit, it is necessary to figure out where in the system it is happening. Until the situation is rectified, the circuit breaker will keep tripping. Hence, the ideal solution would be to call your HVAC technician to find and rectify the problem at its root.
3. A Blown Fuse – Sometimes, the fuse malfunctions. This is a normal occurrence and can happen to anybody. When we talk of a blown-fuse, it means the wire inside the fuse has melted. When that happens, the circuit is broken, and the AC loses power, due to which it stops working.
The Solution – The solution is very simple. You go to a hardware store and buy a new fuse to replace the old one. Once the replacement is complete, the AC will start working.
4. Blocked Air filter – Air filters should be changed monthly, yet many homeowners forget to do that. The result is that it becomes more and more difficult for the air to pass through. One of the problems caused by this restricted airflow is the freezing of the evaporator coils. Once the ice formation build-up becomes massive, it is most likely to shut down the AC.
The Solution – It is time everyone starts prioritizing the need to change the air filters regularly. Changing them is very easy. All you need to be careful about is buying new filters of the exact specification as the old ones.
5. Wiring Problem In The House – Sometimes, the problem is not the AC. Instead, it is only a victim. The actual problem might lay in the home’s wiring. If your lights flicker often or you hear a crackling sound when an appliance is switched on, it means there is a wiring issue in the house.
The Solution – You will have to ask an electrician to check the wiring in your residence. Once they find the culprit wire, it will have to be changed to prevent similar future trouble.
6. Dirty Evaporator Coils – When evaporator coils become dirty, they are no longer as efficient in extracting heat from the air as before. Consequently, the unit works longer and that too under undue pressure. The stress caused can cause overheating of the internal components forcing the unit to shut down.
The Solution – Regular annual air conditioner maintenance is the best remedy for dirty evaporator coils. Schedule it timely, and you will never have to deal with such an issue.
7. Dirty Condenser Coils – The work of the condenser coils is to expel the heat extracted from indoors to outdoors. When dirt accumulates on these coils, they fail to perform this function. Again, this causes overheating of the system, forcing it to shut down.
The Solution – The most viable solution is to ensure regular annual AC maintenance. You also need to see that there are no obstructions around the outdoor unit as that can also cause the same issue. Therefore, do not allow any build-ups near the condenser, and keep the trees and bushes around it trimmed.
8. Motor Malfunction – As the AC ages, its motor suffers wear and tear. Skipping maintenance compounds the problem further. Often the damage to the motor is so much that it stops working altogether. In such a scenario, the AC also stops working.
The Solution – To rectify motor problems, you will have to bank on the expertise of the HVAC technician. The ideal solution involves replacing the faulty motor with a new one, though there might be a chance of repairing the old motor itself in rare cases. Again, that is a decision best taken by the technician.
AC not working does not always spell doom. That only happens in rare cases where the owners have failed to care for their cooling system. Annual maintenance of the air conditioner goes a long way in keeping the unit functioning efficiently and with minimal trouble. If and when the system gives any problem, report it to your trusted technician immediately and request a repair.
