How to Troubleshoot Your Air Conditioner; Why Isn\’t My Air Conditioner Turning On?

If your office\’s cooling system fails, your employees will also suffer. Unfortunately, given the current conditions, the problem cannot be linked fluently and will require professional assistance in restoring and fixing the system. However, if your air conditioner breaks down at home, there is a cost-effective solution.


There are 8 reasons why your air conditioner won\’t turn on and how to fix them.

There are a variety of reasons why your air conditioner isn\’t working. Some of the most prevalent causes are listed below. Does your air conditioner not turn on? (– Examine the switch.)

To begin with, look for a blown fuse or a tripped circuit breaker if your air conditioner won\’t turn on. If the circuit is overloaded, there\’s a good likelihood the problem is a tripped breaker.

It\’s also possible that a power outage blew a fuse or tripped a breaker in your air conditioner.

A circuit breaker has tripped.

It\’s usually a hint that something is wrong with the circuit. Assume your circuit breaker is always tripping. A short circuit in one of the appliances or the wiring could cause The breaker may be tripping due to a ground line fault. There may be a circuit load.

Sick Condenser

A condenser is the outer or external, unit of your air conditioner. Its job is to transfer the inside team\’s heat to the outer landscape.

The condenser might become dusty over time if it is not maintained regularly. Because the soil acts as an insulator, it will have to work harder to spread the heat. The condenser will begin to trip the circuit breaker, preventing your air conditioner from turning on.

However, if you believe that the result will be simple since you can clean the condenser yourself, you are mistaken. It may be time for a professional clean-up once it is no longer working due to dirt. The compressor coil\’s fins can be damaged by careless cleaning, which is worse than the dirt on the waves.

Even so, just like with routine maintenance, you may want to keep cleaning your condenser regularly to help with any major concerns.

Your AC capacitor must fail, releasing contaminants into the air and attracting ducks. It is, nevertheless, an index of a bad capacitor if one or more of the symptoms listed below persists.

  1. The air conditioner does not turn on right away; it takes some time.
  2. It doesn\’t circulate chilly air.
  3. When it first starts, there is a dreadful humming sound.
  4. Your air conditioner shuts off for no apparent reason.
  5. Your air conditioner refuses to turn on.

A faulty capacitor is causing your air conditioner to take a long time to start or not start at all. There could be another reason for the other issues as well. These might include everything from refrigerant leaks to clogged pipelines and pollution. As previously indicated, search for basic solutions first.

The air filter is clogged.

Do you recall the last time you had your air conditioner cleaned?

If the answer is no, continue reading. It doesn\’t matter what kind of air conditioner you have. You must suck out the pollutants!

Still, it\’s a major issue because unclean, clogged particles may prevent your air conditioner from working properly.

Pollutants\’ function is to maintain appropriate air circulation. However, the tailwind is sufficiently hindered if they are clogged with debris. In this situation, rather than shutting down, your system will have to work harder to keep your home cool.

Dirty air pollutants can irritate your outdoor air conditioning equipment, causing it to malfunction and, in some circumstances, prevent it from turning on.

It\’s strange, yet it happens.

The evaporator coil is found in the indoor unit of your air conditioner, whereas the compressor is found in the outdoor unit. Between these two components is the refrigerant line. Warm air from your home does not reach the refrigerant when the tailwind is constrained. The refrigerant also cools to the point where any moisture on the coil freezes.

It\’s frightening, but you don\’t have to be terrified. You can either hire an expert to handle the situation or clean up the pollution yourself. Because the ice on the coils will melt, collect the water as soon as possible. Allow the contaminants to dry completely before turning on the air conditioner.

To cover your AC\’s air sludge cleanliness position, we recommend using a smart thermostat with a ducted system or an intelligent AC regulator for a ductless mini-split unit. Continuous monitoring can help prevent future plug pollutant problems.

Low refrigeration pressure translates to low temperatures, eventually indurating an evaporator coil commodity. The cold liquid refrigerant flows through the refrigerant line when the evaporator coil freezes, causing the girding humidity in the air to indurate.

Dormancy problems

Even so, if you can\’t figure out why your air conditioner isn\’t working, see an addict. It could be a dormancy issue if the AC addict isn\’t turning on. If your cooling system was idle during layoffs and you turned it back on after a while, the blower fan may have difficulty starting to rotate again due to dirt buildup.

Call an HVAC professional; they\’ll know how to start the blower fan manually. Once the suckers are no longer dormant, the problem should go away.

Issues with temperature control: the thermostat isn\’t quite right.

Your air conditioner has unexpectedly quit working. You\’re horrified, so you start calling several air conditioning specialists.

However, take a break for a different option. Have you checked the temperature on your thermostat?

The performance of your air conditioner is affected by the malfunctioning thermostat.

Check your thermostat site\’s display first. However, if the air conditioner is turned off, it cannot communicate that it should be turned on. Also, if you have a battery-operated thermostat, check the batteries.

Even if the batteries are okay, double-check that your thermostat is operating. Set it to a comfortable temperature, 5–6 degrees lower than the inside temperature. Place your hands in front of the AC vane after a few twinkles to experience the cool air.

However, voilà, you\’ve solved the problem! If it\’s switched on however if your air conditioner is still not working, turn off your thermostat and remove the cover to inspect its components. Look for a figure of debris or rust. Look for blown fuses as well; they might sometimes be the culprit. You can clear out the debris with a soft encounter, but corrosion issues require consultation with an expert.

Furthermore, inspect the thermostat for any loose screws or connections. For proper wiring schematics, you\’d have to go to the stoner primer.

control board error.

Sometimes the problem isn\’t serious; it\’s just that you\’re expecting the worst. So, look at the simple effects right in front of you, and double-check the power cord for the case.

If your item has been stored for a season, the power cable may become rasped and worn down. Power outages can also cause cord damage.

To examine the cord properly, open it up. If it appears to be damaged, you will have to replace it.

Perhaps the problem isn\’t with the cord, but with the outlet. Other appliances can be plugged in to see if the outlet operates properly. If none of them works, you\’ll know what\’s causing the problem.

Depending on the extent of the damage, contact a specialist to replace or repair the outlet.

A word of caution: 

you should never attempt to repair a wire or a power outlet on your own. You risk getting an electric shock if you don\’t cut off the powerful force. Turning off the light will never be enough; you must turn off the power from the main power junction box.

An air conditioner that is dirty

When you don\’t use your air conditioner properly, it collects dust, pollen, and dirt. This could, at best, aggravate aversions and asthma. In the worst-case scenario, it has the potential to spread illnesses.

People may notice air conditioner-related health difficulties even though the unit is as clean as a whoosh in some situations.

Issues with electricity

Air conditioners operate best when they maintain a comfortable temperature in the home without causing too much friction. This strategy is thrown off by a power outage. Depending on how long the outage lasts, your home could lose a significant amount of heat, especially during the summer. That temperature rise could be your first sign of something wrong with the HVAC system.

If your air conditioner doesn\’t turn on after the power has been restored, try the steps below to discover if it\’s a minor problem or if more assistance is required. While each HVAC system is unique, this overview should provide you with a broad guideline for most of them.

Look at your thermostat to see whether there\’s a way to completely turn off your air conditioner. Thermostats with both a classic dial and a more modern electronic display should include a method to turn the system off. If you can\’t find one, move on to the next step.

A power breaker may have tripped the circuit brakes linked to your air exertion system. Make sure the switch that regulates your system is entirely switched on in your home\’s main swell box.

For 30 twinkles, turn off your air conditioner. In the summer heat, a half-hour may seem like an eternity, but this time allows your system to reset its circuit and be ready to chill your home once more. To prevent the system from cooling the house, leave it switched off rather than set to a high temperature.

Set your thermostat to around five degrees lower than the current temperature once the 30 twinkles have gone so it can perform more efficiently; your system should be ready to start again after its little rest.

The gutter is overflowing.
