Common Problems with the Delonghi Portable Air Conditioner
#1 Air Conditioner Keeps Shutting Off
Despite being a durable and long-lasting brand, one of the common problems of Delonghi portable air conditioners is short cycling. This is when the air conditioner keeps shutting off and restarting intermittently, often a few minutes at a time.
Short cycling is common in air conditioning units that are rarely cleaned, but can also present in an air conditioning unit with a faulty compressor or malfunctioning parts. Run the self-diagnosis system of your portable air conditioner to troubleshoot the problem, or have one of our HVAC technicians inspect your unit for an accurate diagnostic test.
#2 Air Conditioner Smells Bad
Different smells coming from your Delonghi portable air conditioner indicates different underlying problems with your unit. A musty odor indicates mold, which may have built up in the condensate drain hose, or air exhaust hose. In this case, cleaning the drain lines and air exhaust hose will immediately fix the issue.
Other smells, like the smell of sulfur or a burning, smoky smell, is not from your air exhaust hose, but may come from external sources such as a decaying critter, or car exhaust from the street. However, they may also indicate a refrigerant leak or burning parts, so it is best to shut off your Delonghi air conditioner, and call one of our technicians to fix the issue.
#3 Air Conditioner has a 3-minute Delay After Restarting
The Delonghi air conditioner series, which includes the Delonghi portable air conditioner, features a safety gadget in its compressor that prevents the air conditioner from restarting immediately after shutting down. This delay of three minutes is normal in most Delonghi air conditioner models, and is meant to prevent damages to your portable air conditioner.
#4 Air Conditioner is Not Blowing Cold Air
If your Delonghi air conditioner is blowing warm or hot air instead of cool air, and is not cooling the room sufficiently, then there are a couple of possible reasons. First, a dirty portable air conditioner will not blow cold air as the filthy dust filter restricts air movement around the AC unit. Clean your AC filters, coils, and exhaust hose to fix the issue.
Another reason could be a refrigerant leak, where coolant escapes out of your Delonghi portable air conditioner, causing your AC to create warm air instead of cool air. One of our licensed technicians at Luce Aircon will be able to fix this issue.
How to Reset Your Delonghi Air Conditioning Unit
Reset Point: Power Cord
Resetting your Delonghi air conditioner may help fix any AC issues and error codes, however, it may not fix hardware issues such as a dirty filter or condenser coils. To reset your AC unit, simply shut down your unit, and unplug the power cord. Wait for 5 minutes before plugging your AC unit back in, and power it on to check if restarting your unit solved the issue.
