20 Most Recent DeLonghi PAC A120E 12000 BTU Portable Air Conditioner Questions & Answers

Don't know if this is the type issue you are having. I had my unit leak all over the place last year and found there was ice buildup on the inside of the unit. You would have to remove the cover completely in order to check this out. Also make sure the drain is clear.

The DeLonghi PACA120E Portable Air Conditioner quickly cools rooms up to 400 square feet and comes equipped with several functions that make operation easy and low maintenance. Its 3 operating modes are supplemented with no-drip technology, an adjustable thermostat, 24-hour timer, and much more. This unit truly takes the work out of cooling medium- to large-sized spaces. Multiple Modes and Functions The DeLonghi A120E-also known as the Delonghi Pinguino PAC A120E-offers 3 operating modes and 3 additional operating functions that make this model versatile and energy efficient. Cool Mode: 12,000 BTUs of cooling power help cool large rooms, offices, or basements. Dry Mode: Reduce room humidity by removing excess moisture from the air. Fan Mode: Circulate air to keep your room comfortable without using a lot of energy. Low, medium, high, and an auto-speed are all included (auto speed selects a fan speed for you). Smart Function: Your AC uses Cool and Fan mode based on ambient room temperature. This function will also select your fan speed and keeps your room comfortable without wasting energy. Sleep Function: Using a low fan speed, the AC gradually reduces operation so your room remains comfortable but the AC runs more quietly and efficiently while you sleep. Boost Function: This function is ideal for the summer months and uses the maximum fan speed to rapidly reduce your room temperature. Useful Features Using DeLonghi's patented no-drip technology, this unit is "dripless" under normal conditions, meaning the AC will discharge all of the moisture collected from the air-so you typically won't have to worry about draining the water. When dehumidifying a lot of moisture in Dry mode, excess water may collect in the internal collection tank. Once the tank is full, the air conditioner will automatically turn off to avoid overflow damage. You can also use the included continuous drain hose as a no-fuss way to eliminate excess water as needed. An adjustable thermostat provides additional convenience by allowing you to set your room temperature. The DeLonghi portable AC will cycle on and off to eliminate over-cooling and maintain the set temperature. Additional Features Washable Air Filter: A washable air filter helps remove allergens and other particles from incoming air and saves you money on replacement filters. Quiet Operation: High efficiency compressor and components result in quiet performance. Electronic Controls: The LCD screen displays the timer and temperature settings, while intuitive indicator lights accompany each operating mode. 24-Hour Timer: This feature lets you program your AC to turn on or off up to 24 hours in advance, so it only runs when needed. Window Bracket: Double window bracket is included with purchase for flexible installation. Self-Diagnosis System: The unit includes a self-diagnostic maintenance system that identifies malfunctions should they occur. Remote Control: Use the full-featured remote control to change modes, set the timer, and select a fan speed up to 23 feet away from the receiver (on the front of the unit). Portability: Easy-roll casters and dual carrying handles make it simple to move this model from space to space.

Question edited for clarity. It probably needs a top up of refrigerant gas. Take it into a local refrigeration company.

That means that the switch is broken and is passing power when supposedly off. Claim on warranty, it is dangerous. If they say no, ask if there are any Class Action Lawsuits on it yet? https://www.delonghi.com/en-us/customer-service/warranty ..

:To open the case of a DeLonghi model PACAN125HPEC, locate the screws on the back of the unit and remove them.

So, it sounds like your Delonghi hifi heater is giving you some trouble, man. The constant beeping and the green light on the control board, it's like it's trying to tell you something. My guess is that there's something funky going on with the thermostat. The beeping is probably the heater's way of saying it can't maintain the desired temperature because the thermostat isn't working properly. And the green light, it's like the heater is still getting power and trying to do its thing, but the thermostat is holding it back. One thing you could try is checking the thermostat settings and making sure they're all good to go. If the settings are chill, but the problem persists, it might be time for a new thermostat. You could also try unplugging the heater for a bit and then plugging it back in, see if that helps reset the system. If all else fails, it's best to reach out to Delonghi's customer service or maybe even a professional technician to take a look and give it a tune-up. It's not always easy to fix these things ourselves, so don't be afraid to ask for help.
