Delonghi Portable Air Conditioner Troubleshooting
Whether your AC doesn’t come on or the device isn’t cooling the room sufficiently, the solution may be easier than you think. Contact the company for help, and if that doesn’t work, read the instruction manual!
If your Delonghi portable air conditioner isn’t cooling efficiently, or at all, try these simple fixes before you call a technician — many simple tech issues can be solved with a bit of research and elbow grease.
The easiest way to fix your portable air conditioner is by consulting the troubleshooting section of your user manual. It’s usually near the front of the book and has a list of common problems and their solutions.
Delonghi Portable Air Conditioner Works Only For A Few Minutes
If the portable air conditioner does not work, check these connections:
If there is any kink in the air exhaust hose or if it is tightly coiled, remove the kink or coil this area of the hose. Check that there are no objects blocking the unit from discharging air.
f the unit is turned on but no air comes out of the hose, check to see if the hose is properly connected to the back of the portable AC unit. If it seems loose, attach it firmly using the included fasteners. If you are using it inside your home, make sure that any objects obstructing the hose’s path have been removed.
Delonghi Portable Air Conditioner Won’t Turn On
A portable air conditioner won’t turn on when there is no current. Check that your portable air conditioner is plugged into a wall outlet, and not just a power strip or extension cord.
A tripped internal safety device can also cause this problem. If you’re using a plug-in extension cord, try instead using a heavy-duty outdoor fashion extension cord to see if it works.
Check the fuse box or circuit breaker. If you find that the circuit breaker is tripped, reset it using a circuit tester.
Delonghi Portable Air Conditioner Not Blowing Cold Air (Not Cooling Room)
In most cases, the problem is the filter needs washing and is clogged. If you have time, you can try to take it out and clean. If not, then you should seek professional help to clean it.
If you want to do it yourself, then open the side air exhaust hose port and remove the filter cage (see image). You will see a circular foam filter with a diameter of about 2.5 inches.
If your portable air conditioner isn’t cooling the room, you may need to take a few troubleshooting steps. First, check that the doors, windows, and curtains are shut. This can be an easy step to overlook! If these are all closed, there is still a chance that heat sources like an oven or hairdryer are present in the room.
If the door is open or a window is open, the portable AC unit cannot perform optimally. The air flow will be interrupted, preventing the cold air from being distributed throughout the room. Open windows in conjunction with portable ACs can cause a negative pressure in the room, which leads to hot air flowing back into the room.
Please ensure your room does not exceed this size. If the room is larger, you will need to purchase a larger air conditioner or two units. Also, check that the exhaust hose is properly connected and that the dust filters are clean.
Delonghi Portable Air Conditioner Will Not Run For 3 Minutes After It Has Been Restarted
When you restart your portable air conditioner, it takes a few minutes for the compressor to start up again. This is normal and shouldn’t be a cause for concern. You can use your air conditioner while it’s warming up and it will then kick back on.
Your Delonghi portable air conditioner needs to rest. When you turn it off, you’re causing the unit’s internal compressor to stop working temporarily. Delonghi’s portable air conditioners need three minutes to restart their auto-defrosting function. This auto-defrost function is essential for cooling your room to the right temperature.
Delonghi Portable Air Conditioner Smell Bad
A portable air conditioner is the perfect solution for cooling off small spaces. While these machines are small, they still need regular maintenance to work efficiently. One of the most common problems that plagues portable air conditioners is a clogged filter.
Dust accumulates quickly inside air conditioning units, especially if filters aren’t cleaned often. A clogged filter can reduce airflow and cause the machine to overheat, which will reduce its performance.
For the best results, keep your portable air conditioner clean by regularly cleaning the dust filter and (where applicable) electrostatic filter. This will prevent the unit from emitting an unpleasant odor.
The first step in maintaining the cleanliness of your portable air conditioner is to remove the filters, taking care not to damage them. Then, soak the filters for several minutes in warm water with a small amount of detergent or vinegar, then rinse and let dry.
Delonghi Portable Air Conditioner Keeps Turning Off
No one wants to get caught in a hot room without an air conditioner. If your unit keeps shutting off, you could have a problem. Thankfully, it’s not hard to troubleshoot — check the cause for this issue and find quick fixes to get your portable AC running properly again.
The following are some of the issues that you can try to resolve. The exhaust hose must be connected properly and there should be no kinks or bends in it. The filter needs to be cleaned. Its temperature setting may not be correct for the room, set it lower to cool faster.
Ensure the unit is set to a temperature that makes sense for your location. Low temperatures might be ideal for cooling off a room while higher temperatures can help maintain comfort in the summer heat.
Work around obstructions with the exhaust hose. If it has kinks, remove them or try turning it sideways. The hose should not be placed in direct sunlight, as this can cause damage to the material and reduce its lifespan.
If you’re using a clogged filter, replace it as soon as possible.
Delonghi Portable Air Conditioner Error Codes

Delonghi Pinguino Not Cooling
There are several reasons why a DeLonghi Pinguino might not be cooling. The air conditioner may not be properly sized for the room, the unit may need to be cleaned, or the filters may need to be replaced.
Additionally, the air conditioner may not be properly vented, or the temperature may be set too high.
The air conditioner filters are dirty. Clean or replace the filters according to the manufacturer’s instructions. The air conditioner thermostat is not set low enough. Set the thermostat to the lowest temperature setting.
