How Do You Fix an AC That Stopped Functioning?
Having an AC at home will stop you from feeling hot and irritated during the summer. It’s one of the wisest ways to “defeat the heat”. Apart from that, people are experiencing heat waves across the globe.
For such reasons, the need for an AC unit has become essential. This enabled the worldwide AC demand to yield a profit of $67.32 billion in 2024. Between 2024 and 2028, the market will notice an annual growth pace of 6.24%
But like all other machines, the air conditioner can stop functioning, and it can occur due to many reasons. Comprehending how to fix an AC that stopped working will assist you in fixing the issues on time and also save funds on repairs.
Steps On How To Fix an AC That Stopped Working
When the AC unit stops operating, you must follow the correct troubleshooting steps mentioned below so that the system can work properly again:
1st Step: Problems in the Condenser
A perfect way to fix an AC that stopped working is by inspecting the condenser unit. It’s because, at times, they come unplugged. This type of issue is normal in all the window AC units. Check for a “brown cord” in the system. This cord is connected at the backside on a panel located at the side of the house.
They can get chewed by animals or become unplugged, which can prevent the electricity from flowing to the AC. So, if there is no electricity, the system will not work.
2nd Step: Check for Ice Buildup
If you come across ice on the components of the AC unit, you must let it thaw before switching on the system. The only drawback here is it will take around 24 hours for the ice to thaw. Unclean coil can get clogged, which will drop the temperature and freeze up.
This will not just block the airflow but will also prevent the AC from functioning correctly. Low levels of refrigerant can also cause ice buildup. If you do come across this sort of problem, please contact an AC repair person for help.
3rd Step: Dormancy Problems
The best way to fix an AC that has stopped working is by checking the AC fan. If the fan doesn’t turn on, it might be a dormancy problem.
Otherwise, switching on an AC unit that has been lying inactive since the winter can make it difficult for the fan to rotate again. This happens because of the dirt or debris it has accumulated over those cold months.
It’s advised that you hire a technician as they can easily start the AC fans manually. When the fans are no longer inactive, there will be no more issues.
4th Step: Damaged AC Motor
Do you hear grinding sounds when you switch on the system? Then it’s certainly not a good sign. This type of noise indicates the malfunctioning of the AC motor blades. These components are completely sealed so that they don’t come in contact with the debris, water and outdoor air.
However, due to a lack of servicing or old age, the motor lubrication needed will seep out. Without the oil, the AC motor will wear and will stop functioning completely. If there is a problem with the motor, the external unit cannot dissipate the heat. You can get the motor checked and repaired by a trained technician. Otherwise, you can replace the entire AC unit.
5th Step: Examine the Filters of the AC Unit
Replacing the filers in the AC unit can enable the system to start functioning correctly again. Not replacing the air filters on a regular basis can prevent the air conditioner from running. Air filters can control the flow and quality of the air the unit receives.
The AC needs to obtain airflow so that it can cool the air and keep the air clean. If you do not change the air filter, you will find it blocked and dirty. Once you get it replaced, you will find out that the AC unit is working perfectly.
If you’re not sure whether or not to replace it, you must remove and inspect it. The new air filters are completely white. When your unit has a black air filter, you must get them replaced immediately. You can purchase these filters at a local hardware shop. Before buying, make sure to get the correct size.
6th Step: Test Out the Fuse
Another way you can fix an AC that stopped working is by checking out the AC fuses. Several disconnect units have two cartridge uses. Before you plan to get the repairs done, take a look at these fuses.
If you find a blown fuse, it’s an indication of a damaged part inside the condensing system. Get the parts replaced, install the new fuses and then switch on the unit. If the fuse blows up again, please contact the HVAC professional immediately.
7th Step: Check for Blockages in the Drain Lines and Pipes
The AC unit creates condensation, which is released outside the house through the drain line. When the drain pan is clogged or full, it will trigger the safety switch and shut down the unit. You can easily remove the blockage from the drain line with a pipe snack or a dry/wet vac. Unclogging the drain lines and pan can resolve the issue instantly.
