Gree AC Not Cooling

Your Gree AC is an indispensable appliance that comes in handy when you have to cool down the heat surging through your body. 

Therefore, it’s nerve-wracking when it’s not cooling, especially when the weather is hot outside. 

That’s when frustration and confusion creep in, particularly when you don’t know the source of your dilemma. 

So, what could be the reasons for this abrupt change in this unfavorable weather? And what are the solutions to them? 

Well, I earlier established six reasons for this occurrence. However, I’ll explain each reason individually and offer possible solutions.

So, let’s explore more! 

#1. Clogged/Dirty Air Filters 

This issue is one of the most common reasons your Gree AC fails to cool. If the air filters are dirty or dust clogs them, it’ll adversely affect the cooling capability of your Gree AC.

Possible Solution

Always set the thermostat settings correctly. Set your AC to Auto Mode. This way, your AC will only blow cool air. 

#3. Dirty Outside Unit

Users often ignore the outside unit of their ACs’, which becomes dirty over time due to excessive workload. 

The condenser, which is the outside unit, usually blows cool air inside your room. Hence, when debris/dirt obstructs the condenser, it will not blow cool air. 

Possible Solution

Clean your AC’s condenser regularly and provide enough room to absorb the fresh air. You can do this by eliminating dirt enveloping the condenser. 

#4. Faulty Motors 

This happens when the motors of your AC fan are defective or broken. In this case, the outdoor component fails to dispel heat. 

Therefore, it interferes with the cooling capacity of your Gree AC. 

Possible Solution

Consult a technician to assist you in fixing or replacing the fan motors when you encounter this problem.

#5. Faulty/Damaged Compressor 

This happens when the compressor fails to manage refrigerant passage between the condenser and evaporator. Hence, your AC will not produce cool air. 

Possible Solution

You can fix this problem by replacing the compressor with a new one. 

#6. Low Refrigerant Level 

This usually occurs when the refrigerant is leaking or isn’t enough for your AC which urges it not to cool when needed. 

Possible Solution

You can quickly identify this problem when your AC makes a bubbling or hissing noise. The solution is to call a technician to help you refill the refrigerant. 

I’ll highlight other reasons and quick solutions in the table below. 

Reasons Solutions 
Defective control board Replace the control board. 
Undersized AC Get the right size of Gree AC for your room. 
High atmospheric temperature Always adhere to the optimum temperature limit. 
Faulty AC remote Replace the AC remote with a new one.

With adequate maintenance comes durability beyond the average lifespan of a Gree AC. 

In other words, you must adopt safe maintenance practices regularly to keep your AC running like it’s still brand new. 

However, you might need clarification on the best maintenance practices for your AC. 

If that’s the case, I’ve got you covered, as I’ll highlight five easy maintenance tips to keep your Gree AC functioning properly. Without further ado, let’s delve right in! 

#1. Clean the Air Filters 

The air filters are crucial to your AC; therefore, you must clean them regularly. 

When you fail to clean them regularly, they accumulate dirt/debris, which blocks the passage of cool air. It adversely affects other components of your Gree AC in the process. 

Hence, it’s best to clean them to avoid unnecessary waste of money on repairing other affected components. Furthermore, replacing the air filters when they become defective is advisable. 

#2. Check the Refrigerant Level 

Checking the refrigerant level of your AC is of utmost importance as it determines the passage of cool air. 

If the refrigerant level is low, refill it immediately for continuous functionality of your AC. 

Refilling the refrigerant alone is not advisable, as you might encounter complications. 

Always seek the services of an expert to assist you. Plus, ensure you fill the AC with enough refrigerant to avoid problems. 

#3. Clean the Condenser Coils 

Check and clean the condenser coils as often as possible. This prevents dirt accumulation and enhances the performance of your Gree AC. 

It’s advisable to leave your condenser coils for months with maintenance. It might become defective and fail to function. 

So, it’s best to clean them regularly to prevent immediate replacement.  

#4. Clean the Condensate Drains 

The condensate drains are vital to your Gree AC as they are responsible for proper drainage

When the drain is clogged with dirt/debris, it obstructs the drainage. Removing the dirt/debris from the condensate drains is the best solution. 

#5. Seek Regular Maintenance from a Professional 

If you have a busy work schedule and can’t take maintenance tips, you can always seek the services of an expert. 

The expert should come at least twice a month to inspect your Gree AC and fix or replace any defective component. 

Why Won’t My Gree AC Turn On (Reasons and Solutions)? 

It’s annoying when your AC fails to turn on, especially when your body craves cool air during a hot and sleepless night. 

So, why is your Gree AC failing to turn on to soothe your critical situation? Let’s find out the reasons for this occurrence and their solutions! 

#1. Faulty Thermostat 

When your Gree AC fails to turn on, you should check your thermostat, as it might be faulty. If the thermostat fails to display, check the batteries in the thermostat. 

The batteries might be dead or defective. If that’s the case, replace the batteries immediately. 

If the thermostat still fails to turn on, it’s a huge sign that you must replace it with a new one. 

Sometimes, the thermostat fails to function when its wires or screws are loose. In this case, you can refer to your user’s manual to see the appropriate procedure for reconnection. 

#2. Dead Capacitor 

The capacitor may be dead if you hear clicking sounds from your outdoor AC unit. The capacitor can die when it’s constantly exposed to the sun. 

Furthermore, it can die when it’s subjected to overheating. Since the capacitor is highly susceptible to heat, it doesn’t take long before it breaks down. 

Plus, age is another factor that can take its toll on the capacitor over time of excessive work. The best way to avoid damage to your capacitor is to keep it far from heat. 

Maintain the optimum temperature limit of your AC to avoid overheating, which will preserve your capacitor. If your capacitor is old, replace it with a new one. 

Please don’t attempt to replace the capacitor without assistance, as you might encounter complications. 

#3. Faulty Power Cord/Outlet 

Most times, when your AC fails to turn on, the problem might be from the power cord or outlet. The power cord may wear out over time. 

On the other hand, the power cord might be damaged due to power surges. If that’s the case, you might perceive a burning smell from the socket. 

It’s advisable to unplug the cord and examine it critically to see the extent of the damage. If the damage is severe, replace the power cord immediately. 

Sometimes, the power outlet might be faulty and begin to malfunction. Please always consult an electrician to assist you in fixing these appliances.
