It’s not uncommon for portable air conditioners to stop cooling at some point. There are a few reasons why this might happen, so it’s essential to identify the cause before taking any steps to fix the problem.

What Causes Portable Ac to Not Cool

Plenty of different problems can cause your Blast Auxiliary Portable AC to stop cooling. Some of the most common causes include:

1. Leak in the Refrigerant Line:

If there is a leak in the refrigerant line, it can mean that your unit is low on R410A gas. In this case, your air conditioner will stop working until you have fixed the problem. A professional should be able to locate and fix any leaks that are hampering your unit’s performance.

2. Electrical Malfunctioning:

If you notice that your air conditioner has stopped cooling, it might be due to an electrical malfunction. If this is the case, turn off the power and wait to defrost before restarting the unit. It might take up to an hour or two for the water on the coil to evaporate.

3. Condenser Coil Has Iced Over:

Another common reason why portable air conditioners are not cooling is that the condenser coil has iced over. To fix this, turn off the unit and wait for the ice to thaw before turning it on again. It can take up to an hour or two for the water on the coil to evaporate.

4. Compressor In Your Ac Has Stopped Working:

A much less common reason for a unit not to cool is that the compressor has stopped working. If this is the case, you’ll need to replace or repair it before using your appliance again.

5.  Filter Is Dirty:

A dirty air filter can also cause your portable air conditioner to stop cooling. To fix this, you’ll need to clean or replace the filter before restarting the unit. If it continues to produce warm air, you might need to check for blockages in the condenser and exhaust tubing as well.

6. Unit Is In Defrosting Mode:

If you notice that the unit is emitting cold air, but only for a short time, it might be in defrost mode. It is usual to automatically restart after the coil has evaporated the moisture on it (this can take up to two hours). You’ll need to wait patiently before using your unit again.
