Black and Decker air conditioner not cooling

If your Black and Decker air conditioner is not cooling your space this may indicate an issue with the settings, the ambient temperature or the exhaust hose.

If something has gone wrong with the way that your air conditioner works, the best course of action is usually to check common troubleshooting solutions.

This is also the best solution if your Black and Decker air conditioner is no longer cooling, since incorrect settings, problems with the ambient temperature or underlying issues with the exhaust hose are usually to blame.

Troubleshooting compact air conditioners

Few things are better than having a small and compact air conditioner that can keep your space cool during those hotter, summer months.

However, these smaller units are not bulletproof, and they still experience issues from time to time.

There is an array of things that could go wrong within any air conditioner unit, so troubleshooting a few different common issues is usually the best way to solve specific issues.

Black and Decker air conditioner not cooling

It may seem like a big deal when your Black and Decker air conditioner is not doing the one thing that it was specifically designed to do.

But there is actually a multitude of reasons why air conditioners stop cooling, and there is a good chance that the underlying cause is fairly minor and easy to fix.

Smaller air conditioners are often placed in areas where there is a lot of foot traffic and movement and it only takes one accidental bump or shift to change the settings on the machine.

This is why checking that all of your settings are still correct should be one of your first troubleshooting steps when something has changed suddenly with the operation of your unit.

While you are fiddling with the settings on your air conditioner, it is also a good idea to double-check the ambient temperature in your space, as this can have a measurable impact on the effectiveness of any air conditioning unit and could also easily be the root cause of your problem.

One of the other most common reasons why Black and Decker portable air conditioners stop cooling is because of an issue with the airflow.

This issue can usually be traced back to the exhaust hose on the unit, which could be why it is no longer cooling your space.

Checking the settings on your air conditioner

If you find that the air conditioner is no longer cooling the way that you want it to, then it may be time to ensure that its settings are optimal for your space.

Setting the air conditioner to the “Cool” mode instead of the “Auto” or “Fan” mode should ensure that it is providing you with ample quantities of cool air.

If your unit is set to “Cool”, but is still not blowing cool air (even after 3 minutes), then there may be a bigger issue somewhere in the system.

Black and Decker air conditioners and ideal ambient temperatures

Setting the desired temperature for your air conditioner can be a tricky endeavor.

If your desired temperature is higher than the ambient temperature in your space, then you air conditioner may not be cooling because its thermometers are telling it that the room is cold enough already.

However, if the ambient temperature of your space has increased considerably because of an open window or door letting in warm air or even an appliance causing high temperatures – then your air conditioner may just not be able to cool down the air in the space fast enough for you to feel it working.

The ambient temperature of your space can be accurately measured with an indoor thermometer like the ThermoPro TP49.

Possible issue with the exhaust hose on your Black and Decker air conditioner

The exhaust hose can seem like an unnecessary add-on when you are first setting up your portable air conditioner, but this component is actually an extremely crucial part of the system.

If this exhaust hose is blocked or it is not connected to your Black and Decker air conditioner, then your air conditioner will not be able to expel excess warm air and it will not be able to function properly.

This is why it is so important to check that the exhaust hose is securely connected to the backside of your unit and that there are no blockages within the hose which could prevent proper airflow. 90 degree bends in the hose can also sometimes block airflow or even cause holes and tears within the hose.

If you notice that your hose is damaged, you need to consider purchasing a replacement hose to avoid the leaking of hot air back into your space.
